[EU07] eDelivery

e-Delivery denotes the process to take (store) and hand over (route and forward) business data and evidence asynchronously, securely and reliably:

 interconnected by applying the four-corner model network arrangement

 to form a Pan European Registered e-Delivery ICT Transport Infrastructure

 to and from existing national and/or private ICT Transport Infrastructures to form a bridged Pan European Registered e-Delivery ICT Transport Infrastructure.

The main objective of the e-SENS e-Delivery infrastructure is the interoperable, secure and reliable exchange of structured, non-structured and/or binary data within (at least) asynchronous communication scenarios.

[ISO01] ISO/IEC 19757-3:2006 - Information technology -- Document Schema Definition Languages
(DSDL) -- Part 3: Rule-based validation – Schematron

ISO/IEC 19757 defines a set of Document Schema Definition Languages (DSDL) that can be used to specify one or more validation processes performed against Extensible Markup Language (XML) or Standard Generalized Markup Language

(SGML) documents. (XML is an application profile SGML, ISO 8879:1986.)

ISO/IEC 19757-3:2006 specifies Schematron, a rules-based schema language for XML. It establishes requirements for Schematron schemas and specifies when an XML document matches the patterns specified by a Schematron schema.

[ISO03] ISO NP 15000-5 standard - Electronic Business Extensible Markup Language (ebXML) – Part 5: ebXML Core Components Technical Specification, Version 2.01 (ebCCTS)
This part of ISO 15000 describes and specifies a new approach to the well-understood problem of the lack of information interoperability between applications in the e-business arena. Traditionally, standards for the exchange of business data have been focused on static message definitions that have not enabled a sufficient degree of interoperability or flexibility. A more flexible and interoperable way of standardizing Business Semantics is required. The ‘Core Component’ solution described in this specification presents a methodology for developing a common set of semantic building blocks that represent the general types of business data in use today and provides for the creation of new business vocabularies and restructuring of existing business vocabularies. download
[NL03] QiY

The open Qiy Standard is the protocol describing the exchange of data under control of the individual.

Scheme and open standard define a Trust Framework for individual users, companies and governmental organizations.

Individuals are enabled to obtain full, secure and private control of their personal data and the possibility to share their data of choice with people, companies and governments they are dealing with.

This better user experience means benefits for all parties involved. Ease of use, high quality data, faster processes and lower costs bring innovative business models and revenue streams.

[OA02] OASIS (e.g. UBL) and UNECE (e.g. UN/CEFACT)

OASIS Universal Business Language (UBL) TC defines a common XML library of business documents (purchase orders, invoices, etc.).

Organisations like OASIS (e.g. UBL) and UNECE (e.g.

UN/CEFACT) define business languages and information component libraries that can be reused for the definition of electronic structured documents in Base Registries and crosssector ecosystems.

[OS04] ebXML - ebCCTS - IdentifierType CCTS

[BE02] Criteria from data sources to Base Registries

Reliable recognition of base registries, so that their authentic data can be used to support ‘once only’ data usage. In order to verify whether a data source fulfils all the legal requirements to be officially recognized as a base registry, a compliance verification procedure has been defined that uses a set of criteria to determine the quality, usefulness, governance, security and financing of the data in this data source.

[ES08] Spanish Personal Data Protection law: articles 4LOPD and 8RLOPD

The national law related to the Personal Data Protection is called “Ley Orgánica 15/1999, de 13 de diciembre, de Protección de Datos de Carácter Personal”. It contains several articles related to key topic related to the Data Protection (art. 4 about Data Quality, art. 6 about the citizen consent, art. 7 about special data under protection, art. 9 about the data security, art. 10 about the privacy).

[EU20] Directive 2009/101/EC

The EU Directive 2009/101/EC is related to the protection of the interests of members and third parties, which are required by Member States of companies within the meaning of the second paragraph of Article 48 of the Treaty of the European Union. The current directive takes into consideration the legal background of the First Council Directive on coordination of safeguards (68/151/EEC) which was based on the second paragraph of Article 58 of the Treaty. This directive has adopted five different chapters tackling each one of them key specific issues on safeguards (chapter 1 about scope, chapter 2 about disclosure, chapter 3 about validity of obligations entered into by the company, chapter 4 about nullity of the company and chapter 5 about general provisions).

[EU41] Directive 200398EC

The Directive 2003/98/EC of 17 November 2003 emphasizes on the re-use of public sector information. It provides for the establishment of an internal market and of a system ensuring that competition in the internal market is nor distorted. Harmonisation of the rules and practices in the Member States relating to the exploitation of public sector information contributes to the achievement of these objectives. This directive has adopted different chapters (chapter 1 on general provisions, chapter 2 on requests for re-use, chapter 3 on conditions for re-use, chapter 4 on non-discrimination and fair trading and chapter 5 on final provisions).

[EU42] Regulation 9102014 (eIDAS Regulation)

The Regulation 910/2014 of 23 July 2014 highlights the electronic identification and trust services for electronic transactions in the internal market. It has adopted different chapters divided into sections which remarks the importance of building trust in the online environment which is key to economic and social development (chapter 1 on general provisions, chapter 2 on internal market principle, chapter 3 on trust services, chapter 4 on electronic documents, chapter 5 on delegations of power and implementing provisions and chapter 6 on final provisions)

[NL04] Criteria for selecting data sources as a base registry

The basic records relate to the actions of the government main subjects, objects and the relationships between them. Together they form the scheme of base registries, consisting of authentic information about people, companies, addresses, places and their location (land and topography), vehicles, wages, employment and benefits ratios, earnings, surface, and the value of real estate.

The Netherlands currently has 12 base registers that are part of the “Stelsel van Basisregistraties”, a scheme of base registers.

The scheme of base registers is "the set of agreements and provisions aimed at effective and efficient management of limited data that are necessary for the implementation of the tasks of the government, enshrined in data sets with a legal basis (basic registration) including their interdependence and common facilities required for collection, dissemination and use."

The scheme of base registers can be expanded with registers that meet “12 criteria/principles", and if the added value is considered for the administrations. The added value of the scheme lies not only in the data sets (basic records) itself, but also in their interrelationships, relationships, couplings and arrangements at the level of the scheme as a whole.

[OS07] Guidelines to Open the Government Data

Different recommendations about how to open the Government Data are provided by several organisations. The most important ones are the following:

1. The Open Data Handbook is a guide that discusses the legal, social and technical aspects of open data. It can be used by anyone but is especially designed for those seeking to open up data. It discusses why to go open, what open is, and the how to ‘open’ data. It also presents value stories and a library of resources.

2. The Division for Public Administration and Development Management (DPADM) created some guidelines on Open Government Data for Citizen Engagement. This guide is a practical and easy-to-understand guideline for policy makers and technologists. It can be used to understand, design, implement and sustain open government data initiatives. The document is tailored to the needs and constraints of developing countries, but it can be used by anyone interested in opening up data. It contains the core principles of openness, best practices and case studies, checklists, step-by-step guidelines and practical policy recommendations.

3. And one good example is the story of the Indian government to open Government Data. Policy, Implementation strategy, digital platform, dataset sample and business strategies are presented.


Organisational solutions


The MAGDA (Maximum Data Sharing between Administrations and Agencies) platform provides a service-oriented data exchange infrastructure for accessing base registries of citizen and enterprise data, both at the regional and the local level, and increasingly at the federal level. The platform takes care of authentication & authorization of data users and filtering & logging of data access, in order to comply with privacy protection regulations w.r.t. personally identifiable information.

A service-oriented infrastructure is the only feasible technical means to interconnect disparate base registries and to allow for the exchange of authentic data between these base registries and the applications that want to use that data.

[EE01] X-Road (the EE Interoperability Framework)

The Estonian Interoperability Framework (Interoperability Framework of the State Information System) provides the most relevant decisions concerning open standards. Public sector agrees, at the guidance of the open standards working group and in cooperation with other concerned parties, on the minimum set of public sector open standards, compliance with which is compulsory for the public sector. The choice and assessment of standards is public and balanced.

It lists of the most relevant open standards, which institutions should use when communicating with one another or the public, on web sites and in public registers. With regard to in-house communication, institutions are allowed, although it is not recommended, to use other formats.

[EE02] Agreements between Finland and Estonia about eGovernment initiatives (X-Road)

Estonia and Finland cooperate in developing e-governance and e-information exchange. On December 10, 2013 the prime ministers of the two countries Andrus Ansip and Jyrki Katainen gave their digital signatures to the memorandum of understanding on e-data exchange and X-Road cooperation. With the signing of the memorandum, Estonia and Finland agreed to cooperatively develop the national data exchange layer, also known as the X-Road solution. The basis for this is Estonia’s X-Road source code. In the future it will be possible to offer cross-border e-services.

The following initiatives have been made regarding the two countries' common public e-services, and data exchange: the tax agencies of the two countries have tested the flow of data between the institutions, with co-operative jobs have being studied by social security agencies in Finland and Estonia. The Minister of Education of the two countries are also determined to co-operate in the development of e-learning. The Ministers of Education have agreed on a so-called education cloud, or jointly useable e-learning resources and the creation of a repository of educational applications.

In early February of 2015, an Estonian-Finnish joint analysis of governance in OECD countries was completed, which reviewed the potential of joint cross-border e-services and infrastructure development. The OECD's recommendation is to develop and agree on a more precise road map for the development of cross-border data exchange and services.

Currently, negotiations are being held to develop the launch of such a roadmap.

[EU10] European Union Location Framework (EULF)

European Union Location Framework (EULF) is the ISA action 2.13 of the ISA Programme. The objective of this action is to test the concept of a European Union Location Framework (EULF), an EU-wide, cross-sector interoperability framework for the exchange and sharing of location data and services.

The EULF concept “solution” is intended to offer a package of case studies, specifications, guidelines, training materials, recommendations and actions required by public administrations and stakeholder communities to"facilitate the implementation, use and expansion" of INSPIRE in an e-government context. The EULF will set up an open and interoperable framework that public authorities should use for their procurement. It will complement existing INSPIRE Technical Guidance documents to facilitate the introduction and use of the infrastructure in new thematic sectors.
[EU12] PM2- Governance

Governance is the act of governing and is therefore concerned with how decisions will be made. In the Commission, governance is a process to develop a more strategic approach to projects/programmes, in order to achieve an efficient use of the Commission's resources and investments and to ensure that business needs are supported by efficient tools. This process is performed by the Governance Bodies.

The PM² methodology recognizes the complex and uncertain nature of many types of projects and the positive contribution of the agile way of thinking to their effective management. Moreover, it helps project teams take decisions on trade-offs between the project dimensions of time, cost, scope and quality. PM² describes the governance at project level, which supports project governance model, project lifecycle and a set of processes and related artefacts.


RUP@EC is the software development methodology used in the European Commission. RUP@EC is a tailored version of the "out of the box" version of RUP. It describes the engineering and processes in terms of disciplines, workflows, roles, activities, artefacts, templates, tool mentors and reports.

We have two variations of the RUP frameworks: RUP@EC and Agile.


Agile RUP@EC is based on the IBM Rational Disciplined Agile Delivery ® (DAD). It provides a lighter approach by incorporating agile practices which are less descriptive and recommended for smaller projects of lower risk. It uses the scrum development lifecycle while maintaining a common basis with RUP@EC.


European Federated Interoperability Repository (EFIR) is the ISA action 4.2.4 of the ISA Programme. There is no European access point which provides detailed, up to date information, on all types of interoperability assets of the Member States. Although some of the interoperability assets are already listed in EU portals, these portals concentrate either on a specific European Interoperability Framework layer (e.g. the semantic layer for SEMIC.eu) or provide high-level information, which is of limited use when implementing an interoperability architecture in the Member States (e.g. The National Interoperability Framework Observatory).

This Action should coordinate and support relevant work in action 1.1: Promoting semantic interoperability amongst the EU Member States in order to provide a European Federated Interoperability Repository (EFIR) located on the Joinup platform, which contains important interoperability assets of the Member States:

- Repository: the Action shall provide a reusable tool (software system), which allows the Member States to manage their interoperability assets on a national/regional level and to share these assets with the European Union and with each other.

- Interoperability assets of the Member States: the repository should come with an initial set of interoperability assets coupled with the identification of challenges, conflict areas and opportunities for alignment amongst interoperability assets across Europe.

The EFIR concentrates on content (interoperability assets) rather than on collaboration. It es implemented as an extension to the existing Joinup repository which currently covers the documentation of semantic and open-source software interoperability (IOP) assets.

The EIFR is on one side a common (central) service run by the European Commission and on the other side a re-usable generic tool, downloadable and usable by national public administrations as part of the Joinup platform.

[EU24] EIF

The European Interoperability Framework (EIF) is a set of recommendations which specify how Administrations, Businesses and Citizens communicate with each other within the EU and across Member States borders. The EIF 1.0 was issued under the Interoperable Delivery of European eGovernment Services to public Administrations, Businesses and Citizens programme (IDABC). The EIF continues under the new ISA programme, which replaced the IDABC programme on 31 December 2009. EIF in effect is an Enterprise architecture framework targeted at the largest possible scale, designed to promote integration spanning multiple sovereign Nation States, specifically EU Member States.

A good place to see how all the MS develop their own Interoperability Framework is the “National Interoperability Framework Observatory (NIFO) Factsheets”. The NIFO helps countries to align their interoperability frameworks with the one that they agreed on with the European Commission, the European Interoperability Framework (EIF). This is done using a model made to analyse, compare and show the gaps between the different aspects of the national frameworks and the EIF.

[EU28] Federated Authorisation - ISA Action 1.18

Federated Authorisation is the ISA action 1.18 of the ISA Programme.

ISA Action 1.18 aims at demonstrating that authorisation information attached to an identity assertion can be used to grant access to European Commission systems.

[EU35] TES (Trans-European Systems) Study and the ISA’s Action 2.14

Trans-European Systems (TES) is the ISA action 2.14 of the ISA Programme.

The European Commission is currently implementing an overall strategy to rationalize and streamline the IT systems it develops, maintains and operates. A similar process is also on-going in Member States at their national or even regional levels.

The aim of this rationalization is to avoid duplication and promote common, reusable and flexible solutions. Rationalizing the number of information systems supporting EU policies will result in a reduction of costs in terms of development, maintenance, implementation, operation and training at the EU and national level. At the same time the use of a reduced set of solutions, methods, processes and tools will simplify cooperation between EU wide administrations.

This action targets systems that support EU policies and exchanges between European Public Administrations at European and national level. It also covers those systems managed by the European Commission allowing for exchanges between Member States.

A study will define assessment criteria for the rationalization, describe the building blocks, deliver an analysis based on these criteria and propose a list of rationalization opportunities.

It will also provide a map which will be the basis for a strategic plan to boost the reuse and sharing maturity of the EU systems. At the same time it will provide input to the EU cartography to be built in the context of the “European Interoperability architecture” (EIA) Action.

[FI01] MyData
This white paper presents a framework, principles, and a model for a human-centric approach to the managing and processing of personal information. The approach – defined as MyData – is based on the right of individuals to access the data collected about them. The core idea is that individuals should be in control of their own data. The MyData approach aims at strengthening digital human rights while opening new opportunities for businesses to develop innovative personal data based services built on mutual trust. download

This Code of Conduct (CoC) is supplementary to the EULIS EEIG Agreement (Agreement), the EULIS EEIG Association Contracts (Contract) and the EULIS EEIG Level-2 and Level-3 Contracts (Level-2 and Level-3 Contract), and should be read in  conjunction with these primary documents. The CoC establishes the framework required to facilitate the success of EULIS, including the involvement of EULIS as a partner in projects at a European level (e.g. e-Justice).


The CoC provides the procedures for the management and operation of EULIS.

[LR01] Cross Border Electronic Conveyancing (CROBECO)
Process for foreign electronic purchases of real estate in countries where registration of foreign deeds is permitted. The project is named CROBECO. It aims to set out a European framework of rules and principles for a process that, for contractual and non-contractual obligations, is based on the law choice of the two parties and the use of digital means. The framework is referred to as the “Cross border Conveyancing Reference Framework” (CCRF). The CCRF focuses on bilateral agreements, with respect for existing legislation. This means that, although the existence of different systems will lead to different demands, the CCRF should be applicable in Member States (MSs) with different legal systems. download
[NL01] Stelselcatalogus

It also describes the working progress between team level development and business strategy. It provides PSI and Release Planning, and it is constantly evolving (free IP framework).
[OS05] Data Quality Assurance Tools

The Data Quality Assurance Tools is a set of methods for assessing M&E plans and systems that collect and report data for program management and reporting. It is composed of two

important parts:


1. DQA & RDQA Toolkit: the MEASURE Evaluation data quality assurance suite of tools and methods include both data quality auditing (DQA) tools designed for use by external audit teams and routine data quality assessment (RDQA) tools designed for capacity building and selfassessment.


2. M&E Systems Strengthening Tool: this tool includes three checklists that program managers can use to assess M&E plans, take stock of the capabilities of management units to manage data, and assess data-collection and reporting systems.

[OS14] Australian Digital Continuity Plan

Digital continuity is an approach to keeping and managing digital information to ensure that it can be used in the way that is required for as long as required, and no longer.
Digital continuity ensures information is complete, available and usable by those with a need for it. It also ensures the informationis not kept for longer than needed. Information is useable when you can:
- find it when you need it
- open it when you need it
- work with it in the way you need to
- understand what it is and what it is about, and
- trust that it is what it says it is.
Information is a key component of normal business activity, yet information today is more vulnerable than it ever has been.
Agencies cannot afford to ignore information management, because lost, unreliable or poorly controlled information can have a significant impact on the quality and effectiveness of decision-making and other aspects of business. Increasingly, information in digital formats comprises a major component of business. As a consequence, digital information management needs to be considered as an integral component of business governance.
Decisions that impact digital continuity should be based on an understanding of risks and the costs and the value of the information. Responsibility for digital continuity rests with individual agencies.

Your agency can use this document and other more detailed advice to formulate and implement a plan to address digital continuity. Your plan should include a staged or incremental approach to digital continuity, addressing areas oh highest business priority and business risk first.

[BGR01] RegiX (Registry information exchange system)

RegiX is a software infrustructure that enables theautomated interconnections between multiple Bulgarian registries (currently 62), as well as infromation systems, in form of machine-to-machine servicies.

RegiX has been developed as part of the central e-government system. The environment for automated interconnections between registries is defined as a way of facilitating interaction between administrations, whith the goal of providing intergrated administrative servicies. This would lead to administrative authorities that provide public servicies, not to require citizens or organisations to provide more than once the data tah tthe administration already has. Instaed, they must collect it officially from the primary administrator or the data. Via RegiX, notification and request for data is done electronically and automatically as a n internal electronic service. 

[OS10] WORM Solutions

Write once read many (WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device.

On ordinary (non-WORM) data storage devices, the number of times data can be modified is limited only by the lifespan of the device, as modification involves physical changes that may cause

wear to the device. The "read many" aspect is unremarkable, as modern storage devices permit unlimited reading of data once written.

At operational level, NORA also handles other issues that are organised by themes such as use cases, digital preservation, semantic assets, etc.) download
[PT01] Public Administration interoperability platform

The Portuguese public administration interoperability platform (iAP) is a cenral, service-oriented platform that serves all the public administration levels. The iAP was created to deliver the public authorities with shared tools for sharing messages, interconnecting systems, providing federated identity mechanisms, secure authentication or payments. These tools are available via four independent macro-services: the integration platform, the authentication provider, the public administrations' payments platform and the SMS gateway for public administration.

By implemennting one single platform at central level , the iAP ensures taht the public administration, via one connection, are linked among each other in a secure manner through one private network. 

The iAP also allows the availability of multichanne elecctronic services adapted to citizens and businesses' needs.

The iAP project tackles all levels of interoperability: the legal, organisational, semantic and technical one.

Specification which defines a common data model for describing business events and public services under the scope of the Services Directive, with a particular focus on the electronic Points of Single Contact. download
[EU14] BRITE REID identifier

The aim of the REID (Registered Entity IDentifier) initiative is to establish a way in which entities in business registers can be identified by a number that is unique at the world level.

This issue is quite general but has been progressed as a core requirement in the BRITE project. BRITE is the acronym for “Business Register Interoperability Throughout Europe”. It is an EU Commission funded research project on the establishment of links between Business Registers. BRITE will focus on the

practical communication links that will assist in the management of the registries in the face of increasing cross border trade in a

multi-language environment.

[EU15] Common Procurement Vocabulary

The Common Procurement Vocabulary (CPV) is a standard taxonomy with coded concepts that is used in Public Procurement to identify the object of a contract (promoted by the European Commission). It establishes a single classification

system for public procurement aimed at standardising the references used by contracting authorities and entities to describe the subject of procurement contracts. CPV has to be used for public procurement covered by Community directives, and then be used and understood by

possible respondents.

[EU16] ESCO taxonomy

ESCO is the multilingual classification of European Skills, Competences, Qualifications and Occupations. It identifies and categorises skills/competences, qualifications and occupations

relevant for the EU labour market and education and training, in 25 European languages. The system provides occupational profiles showing the relationships between occupations, skills/competences and qualifications.

ESCO is the only European standard terminology linking skills and competences and qualifications to occupations and will be available free of charge to all labour market, education institutions and other stakeholders.

[EU17] Eurostat NACE codes

The Statistical classification of economic activities in the European Community, abbreviated as NACE, is the nomenclature of economic activities in the European Union (EU); the term NACE is derived from the French Nomenclature statistique des activités économiques dans la Communauté européenne. Various NACE versions have been developed since 1970.

NACE is a four-digit classification providing the framework for collecting and presenting a large range of statistical data according to economic activity in the fields of economic statistics (e.g. production, employment and national accounts) and in other statistical domains developed within the European statistical system (ESS).

[EU18] DCAT Application Profile

The DCAT Application profile for data portals in Europe (DCAT-AP) is a specification based on the Data Catalogue vocabulary (DCAT) for describing public sector datasets in Europe. Its basic use case is to enable cross-data portal search for data sets and make public sector data better searchable across borders and sectors. This can be achieved by the exchange of descriptions of datasets among data portals.


In February 2015, the ISA Programme of the European Commission has started an activity to revise the DCAT -AP, based on experience gained since its development in 2013.

[EU31] European CEN/BII Workshop-II deliverables “Guideline on Code List Management”

This CWA is a deliverable of the second CEN Workshop on Business Interoperability Interfaces for public procurement in Europe (WS/BII2). The objective of the BII initiative is to provide a framework for interoperability in pan - European electronic procurement transactions, expressed as a set of requirements and technical specifications. The requirements are input into UN/CEFACT in order to ensure global interoperability. The interoperability interfaces are seen on multiple levels. On the business level, it includes agreement of business processes and semantic document models. On the syntax level it includes usages of XML documents compliant with schemas from eBusiness standards like UN/CEFACT XML and OASIS Universal Business Language. On the Technical level, it implies common requirements for document conformance, usage of digital signatures and a document transport infrastructure. The set of CWA’s addresses the next step of standardization for the data exchange within an infrastructure shared by business partners. The focus is the semantics of the procurement business processes supported by XML based vocabularies specified by UBL and UN/CEFACT. This is expressed in the CWA profile descriptions. A profile description is a technical specification describing:

- The choreography of the business processes.

- The business rules governing the execution of these business processes.

- The information content of the electronic business transactions exchanged by pointing to a given information requirement model for each of the business transaction.

The information requirement models in this CWA are syntax neutral, implying that they could be bound against any existing syntax solution. WS/BII2 is providing the relevant syntax mappings to UN/CEFACT XML and UBL. On the other hand WS/BII2 does not provide any XML schemas, but relies on the XML Schemas published by UN/CEFACT and UBL. The target audience for the BII specifications is owners of public processes, operators and providers of public procurement systems, including public procurement agencies. Operators and providers of B2B procurement systems can take advantage of the specification as well. Some specifications require technical

knowledge within the XML and network technology as well as business experience within procurement.

[EU36] SEMIC - “10 Rules for Persistent URIs”

This document explores best practices on the publication of Uniform Resource Identifiers (URI) sets, both in terms of format and of their design rules and management.

The recent development of open data and the desire to increase its interoperability have led to an increased reliance on URIs as identifiers for a wide variety of concepts; everything from languages to buildings, government departments to currencies.

So, as a conclusion of this study, ten rules were proposed to enforce the correct implementation of the Persistent URIs

[EU37] SEMIC - the “Handbook for using the Core Vocabularies”

The handbook for using the e-Government Core Vocabularies provides a generic approach for reusing the Core Vocabularies in order to design new data models and align with existing ones. The approach is syntax-neutral, i.e. independent of any technical representation, and can be used together with other methodologies for creating information system data models, information exchange data models or linked data models. The handbook illustrates two use cases of the Core Vocabularies: 1. to design new data models based on the Core Vocabularies, and

2. to create mappings between existing data models and the Core Vocabularies. Different types of data models can benefit from the existence of the Core Vocabularies and the provided mappings to standard syntaxes:

1. Design of a new domain data model. In this case, the Core Vocabularies can be used as the context-neutral starting point. Such new domain models, based on the Core Vocabularies, can also be used when designing a complete information system data model. This will ease the interoperability, smoothing the eventual integration with external collaborative business processes (interoperability-by-design).

2. Design of an information exchange data model. The Core Vocabularies and the mappings to standard syntaxes can be used to create technical guidelines for information exchange specifications. Data models that map to or extend the Core Vocabularies guarantee a minimum level of cross-sector and/or cross-border interoperability that can be attained by public administrations.

[EU38] the EPSI Platform
The ePSIplatform is a European Commission (DG CONNECT) initiative with the objective of promoting a dynamic Public Sector Information (PSI) and Open Data re-use market across the European Union.

This portal highlights:

- news on European PSI and Open Data developments;

- legal cases surrounding the re-use of PSI;

- good practices and examples of new products and services created through Open Data re-use.

- events, workshops and webinars around Europe. The ePSIplatform now covers many different themes, including Science and Technology, Health, Transport and Environment, amongst others. This makes it easier and faster for users to explore and discover content.

[EU39] The European Open Data Portal
The EU Open Data Portal is the single point of access to a wide range of data held by EU institutions, agencies and other bodies. The portal is a key element of EU open data strategy. The portal allows anyone to easily search, explore, link, download and reuse the data for commercial or non-commercial purposes, through a catalogue of common metadata. Through this catalogue, users access data stored on the websites of the EU institutions, agencies and other bodies. Semantic technologies offer new functionalities. The metadata catalogue can be searched via an interactive search engine (Data tab) and through SPARQL queries (Linked data tab). There is also a showcase of visualisation applications from various EU institutions, agencies and other bodies. Users can suggest data they would like the portal to be linked to, give feedback on the quality of data obtainable and share information with other users about how they have used it. The interface is in 23 EU official languages, while most metadata are currently available in a limited number of languages (English, French and German). Some of the metadata (e.g. names of the data providers, geographical coverage) are in 23 languages following the translation of controlled vocabulary lists that are used by the portal. download
[EU40] The National Open Data Portals
The European Commission activity in this area includes:

- Developing an open data portal site for any type of information held by the Commission and other EU institutions and bodies. The EU Open Data Portal went live in December 2012. The portal is entirely built using open source solutions: the LAMP software bundle, the Drupal content management system and CKAN, the data catalogue software developed by the Open Knowledge Foundation. Its metadata catalogue is built on the basis of the Dublin Core, the data catalogue vocabulary DCAT and the asset description metadata schema ADMS.

- Developing a pan-European digital service infrastructure for open data with a view of providing multi-lingual access to data published by public administrations at all levels of government in Europe (EU countries, countries of the European Economic Area and certain other European countries). The core feature will be a metadata repository harvesting metadata references to data published by public administrations in those countries and present those metadata references in a common format (DCAT application profile for data portals in Europe). A web portal and an application programming interface (API) will make it searchable. This infrastructure is currently being developed. It is funded by the Connecting Europe Facility programme.

- Working with EU Member States on data formats and interoperability between existing open data portal sites at State, regional or local level. The Commission wants to increase public access to high-value, machine-readable data sets generated by European, national & regional governments and public administrations. However, such data sets are found in several, diverse locations, which makes it difficult for people to find them. The Commission funds the "LOD2 - Creating Knowledge out of Interlinked Data" project, which developed a prototype pan-European search portal, publicdata.eu. This harvests metadata information from existing open data portal sites in Europe and makes them searchable through a multi-lingual user interface.

- Contracting services to support data holding entities wishing to publish data on an open data portal, providing technical assistance on data preparation, transformation and publication and related training and IT advisory services. Online training material can be found here.

And two other initiatives are helpful to identify and reuse public information:

- DataPortals.org is the most comprehensive list of open data portals in the world. It is curated by a group of leading open data experts from around the world - including representatives from local, regional and national governments, international organisations such as the World Bank, and numerous NGOs.

- PublicData.eu is a Pan European data portal, providing access to open, freely reusable datasets from local, regional and national public bodies across Europe.

[OS02] MDM Solutions
Master Data Management (MDM) comprises the processes, governance, policies, standards and tools that consistently define and manage the critical data of an organization to provide a single point of reference.

In computing, a Master Data Management tool can be used to support master data management by removing duplicates, standardizing data (mass maintaining), and incorporating rules to eliminate incorrect data from entering the system in order to create an authoritative source of master data. Master data are the products, accounts and parties for which the business transactions are completed.

Master Data Management has the objective of providing processes for collecting, aggregating, matching, consolidating, quality-assuring, persisting and distributing such data throughout an organization to ensure consistency and control in the ongoing maintenance and application use of this information.

Processes commonly seen in Master Data Management include source identification, data collection, data transformation, normalization, rule administration, error detection and correction, data consolidation, data storage, data distribution, data classification, taxonomy services, item master creation, schema mapping, product codification, data enrichment and data governance.

The tools include data networks, file systems, a data warehouse, data marts, an operational data store, data mining, data analysis, data visualization, data federation and data virtualization. One of the newest tools, virtual master data management utilizes data virtualization and a persistent metadata server to implement a multi-level automated master data management hierarchy.
[OS06] Open Data Licensing (pack)
In most jurisdictions there are intellectual property rights in data that prevent third-parties from using, reusing and redistributing data without explicit permission. Even in places where the existence of rights is uncertain, it is important to apply a license simply for the sake of clarity. Thus, if you are planning to make your data available you should put a license on it – and if you want your data to be open this is even more important.

The Open Definition propose a guide to define which licenses can be used. Also, other specific legal frameworks are available:

1. Public Domain Dedication and License (PDDL): This is a simple license to define under which conditions people or organisations are able to share, create and adapt the database.

2. Attribution License (ODC-By): The Open Data Commons Attribution License is a license agreement intended to allow users to freely share, modify, and use this Database subject only to the attribution requirements already defined.

Open Database License (ODC-ODbL): As PDDL, this is a simple license that enable you to define under which conditions people or organisations are able to share, create and adapt the database. This license only applies for Data and Databases, and it is more restrictive than PDDL.
OS08] PURLz (Persistent URLs)
PURLs are Web addresses or Uniform Resource Locators (URLs) that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. Instead of resolving directly to Web resources (documents, data, services, people, etc.) PURLs provide a level of indirection that allows the underlying Web addresses of resources to change over time without negatively affecting systems that depend on them. This capability provides continuity of references to network resources that may migrate from machine to machine for business, social or technical reasons. download
[OS09] Preservation Standards PREMIS & PRONOM (pack)
The PREMIS Data Dictionary for Preservation Metadata is the international standard for metadata to support the preservation of digital objects and ensure their long-term usability. Developed by an international team of experts, PREMIS is implemented in digital preservation projects around the world, and support for PREMIS is incorporated into a number of commercial and open-source digital preservation tools and systems. The PREMIS Editorial Committee coordinates revisions and implementation of the standard, which consists of the Data Dictionary, an XML schema, and supporting documentation.

PRONOM is a web-based technical registry to support digital preservation services, developed by The National Archives of the United Kingdom. PRONOM was the first and remains, to date, the only operational public file format registry in the world, although the "Magic File" repository of the File Command has served this role in a less formal capacity for two decades. Other projects to develop technical registries, including the UK Digital Curation Centre's Representation Information Registry, and the Global Digital Format Registry project at Harvard University, are now in progress

[OS13] Catalogue of Code Lists (MDR – MetaData Registry)
The Metadata Registry registers and maintains definition data (metadata elements, named authority lists, schemas, etc.) used by the different European Institutions involved in the legal decision making process gathered in the Inter-institutional

Metadata Maintenance Committee (IMMC) and by the Publications Office of the EU in its production and dissemination process.

The following definition data are maintained in the Metadata Registry:

- Named Authority Lists (Common Authority Tables/Value lists)

- IMMC Core metadata exchange protocol

- European Legislation Identifier (ELI)

- OP Core metadata element set

- EuroVoc thesaurus and alignments (SKOS/XML distributions)

- Common Data Model (CDM) - Ontology of content and metadata repository CELLAR

[SK02] Central meta information system of public administration (MetalS) 

The central meta Information System of public administration (MetaIS) is aimed at monitoring e-services across all levels of government. While its pilot-test was initiated in 2011, MetaIS became operational later in 2016. MetaIS is currently beign implemented and gathers infromation abbout national e-government services, municipal services, public information systems and code lists. This information is presented in a user-friendly way so that both civil servants and citizens can easily access it. As such, MetaIS fosters, on the one hand, the use of national digital public services and, on the other hand, transparency towards public administration e-government data and services.

MetaIS is structured into the following sections:

-Monitoring project and services metrics;

-Life situations: view of citizen on business processses;

-URI: list of reference identifires;

-Projects: including feasibility studies and development concepts;

-Enterprise architecture: architectures of public administration;

-Data elements catalogue;

-State software licenses Oracle and Microsoft;

-Standartisation socuments: standards for information system of public administration;

-List of reference registries.

In the other side, the Central Meta Information System of Public Administration srves as a catalogue of nationale base registries. It provides information regarding the inclusion of new registries into the catalogue, how to modify the information of the registry and information on the reference data administration.

The system offers, among others, a substantial amount of up-to-date information and recources related to semantic interoperability. Some examples are: code list, reference identifiers and definition of base registries and their data (through the cata logue of registries). Each entry encludes basic information on the base registry such as the registry name, registry code, date of inclusion into the catalogue , registry recponcible/administration and contact information, etc. Additionally, each entry keeps the identification of reference data held by the registry, including ontologies in OWL format.

[W3C01] DCAT Specification
DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use.

By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.

[W3C02] Semantic Web standards
The Semantic Web is an extension of the Web through standards by the World Wide Web Consortium (W3C). The standards promote common data formats and exchange protocols on the Web, most fundamentally the Resource Description Framework (RDF).

According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries". The term was coined by Tim Berners-Lee for a web of data that can be processed by machines. While its critics have questioned its feasibility, proponents argue that applications in industry, biology and human sciences research have already proven the validity of the original concept.

The Semantic Web provides many data model specifications (RDF, RDFS, OWL, SKOS), some rules specifications (SWRL, IF), and one famous search language specification (SPARQL). Data formalised with the Semantic Web specifications (also called Linked Data) can be stored in Triple stores such as Virtuoso, Owlim, etc. Finally, Linked Data applications can be built with the programming frameworks (Jena or Sesame).
[W3C03] SKOS ontology for the definition and expression of taxonomies, lists, etc.
Simple Knowledge Organization System (SKOS) is a W3C recommendation designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary. SKOS is part of the Semantic Web family of standards built upon RDF and RDFS, and its main objective is to enable easy publication and use of such vocabularies as linked data. download
[W3C04] 5 Stars principles of Linked Open Data
In computing, linked data (often capitalized as Linked Data) describes a method of publishing structured data so that it can be interlinked and become more useful through semantic queries. It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried.

Tim Berners-Lee, the inventor of the Web and Linked Data initiator, suggested a 5 star deployment scheme for Open Data:

1. make your stuff available on the Web (whatever format) under an open license

2. make it available as structured data (e.g., Excel instead of image scan of a table)

3. use non-proprietary formats (e.g., CSV instead of Excel)

4. use URIs to denote things, so that people can point at your stuff

5. link your data to other data to provide context.

Technical solutions

[AT 01] EDIAKT II EDiAKT II is a standart for electronic file xchange which was released in 2005. It describes the format for communication between two 'users' by electronic files, business cases and processes (including documents). While its predecessor EDIAKT was a standart for the exchange of electronic files among Austrian authorities at the federal level and business for servicies, EDIAKT II can be used at all governmental levels (local, regional and national). Additionally, EDIAKT II considers the customer perspective on the exchange of electronic files, inclusing businesses and citizens. EDIAKT II is also a standard for long-term archiving of electronic files. Whereas EDIAKT require a specific hardware and software infrustructure to create and exchange files, EDIAKT II follows an open source approach. download
[BR01] Search engine on the e-Justice Portal
Facility to search and retrieve data, documents and particulars on Limited Liability Companies (and its branches) registered in any of the countries of the European Union. This solution illustrates how to solve the need for searching data and documents through a half-centralised half-decentralised cross-border and multilingual/multi-alphabet system.

This need is frequently found in different Member States where search in the systems of different levels of administrations, within one large Administration or at the pan-European level has to be solved.

[BR02] Architecture approach - Hybrid
Centralised system with hybrid access to the common set of free data download
[BR07] Payment 
Electronic on-line system, available from the e-Justice Portal that is part of the BRIS Platform. Currently under analysis for its organisational and technical development.

It will allow the cross-border payment to Business Registries of the particulars and documents on companies and branches that the user searches and retrieves across Europe and that may be served by several Base Registries located in different Member States.

It envisions a highly friendly interface that will allow for paying only once, and in one single currency, to all the Base Registries where the user gets data from.

The systems will be composed of different parts: one of them is the e-Justice Portal from where the user launches his/her search and checks out the documents and particulars of his/her

interests (basket); The rest of the transaction will be subcontracted by the European Commission to a Payment Service Provider whose mission is (i) to collect the money paid by the user; (ii) to signal to the BRIS Central Platform (ECP) that the Business Registries can start delivering the data; (iii) to reimburse each Business Registry with the corresponding part of the money paid by the user.

The data for which the user has paid is delivered by the Business Registries to the ECP. The user will receive an e-mail with the links to the data (i.e. documents). The ECP will store this data for a short period of time (initially 5 days). After that period the user will not be able to retrieve it again as the data will be eliminated from the ECP.

[BR24] Subscription List
Subsystem within the BRIS ECP (European Central Platform) that allows the notification of company dissolutions only to those Business Registries that have branches of the dissolving company registered.

The solution solves a complex legal and organisational situation in which the Business Registries that register companies do not know which branches the company has in other MS neither which Business Registers hold data on the company and branches in those EU countries.

The Business Registries that register data on parent companies do not hold data on its branches. However, when registering data on a branch the Registers always capture data on the parent company of the branch.

The Registries that keep data on the branches notify the BRIS ECP that they are interested in the parent company of that branch.

The ECP registers in a central database the Registration

Number of the branch (together with the identifier of the Business Registry and the Country Code) and links it to the Registration Number of the company.

When an event related to the dissolution of the parent company arrives to the ECP (e.g. the striking-off, an insolvency or winding-up proceeding initiation or termination), the ECP sends a notification on that event only to those Business Registries that showed interest in that company.

The system’s web interface replaces the traditional exchange of printed documents, such as submitting tax returns, and allows for immediate access from any Internet-connected computer. Technical specifications of the system are publicly available, and applications for mobile devices are offered by third parties. The use of the system is mandatory for the state administration and legal entities, and citizens may choose to set up a data box of their own if they so choose. In that case, the state administration is obliged to use the data box for communicating with them. download
[CZE03] Government Service Bus (eGSB) The eGSB provides the infrastructurefor teh exchange of data between basic base registries and other authoritative government data sources. The eGSB is also the centarl point that allows for the acess to the Information System of Base Registries (ISZR)  servicies and the exchange of data between base registries and the genda information systems (AIS). The ISZR is the information system of the base registries, and it describes the links between base registries and the AIS. The AIS is the basic and te most important access point to the reference data in base registries. The eGSB is also used for handling inquiries from data providers. It enforces defined schemas and develops and maintains an audit trail of all transfer and exchange of data.   download
[CZE04] Public Administration Communication Infrastructure (KIVS)

The Public Administration Communications Infrastructure (hereafter referred to as KIVS) integrates several data networks form different public authorities into one data network. Therefore, it interconnects public administration bodies, such as ministries, central administrations, regional authorities, municipal officies. KIVS provides access to cenral information and ensures seure data and voice communications. KIVS is designed as a cenralised communications infrastructure with a central service point (CNS- Centralho mista sluzeb in Czech).

The Public Admnistration Communications Infrastructure was created in 2001. By 2007 all the state administrations had obliged to join KIVS. The retionale behind the KIVS' concept was, to set up one secure, inerconnected and efficient network, and to end the monopoly of data providers' by introducing more suppliers.

The Administration System for the State Information System (Riigi Infosusteemi Halduse Infosusteem, RIHA) can be understood as a catalogue for the Estonian information system inclusing, among others, information on databases and information systems, types of existing data and services, or the reusable components that ensure interoperability. RIHA is also a procedural and administrative environment that ensures an appropriate and comrehensive development and management of the information systems and databases, the registration of serices, the connection with X-Road, and the administration of reusable components. In addition, RIHA serves asa tool for developers, admnistrators and users of the Estonian infromation system. The objective of RiHA is to support interoperability of public sector infromation, the life-sucle management of information systems, and the reuse of data. It serves as the national registry of systems, somponents, services, data modelsand semantic assets.

The use of RIHA is mandatory for all state agencies. 

[EE05] Data Embassy

In 2013, The Estonian government started the Data Embassy initiative. The goals behind the initiative were to implement an additional security measure in the e-government system, improve and increase their digital continuity, and avoid national stoppages of services (e.g. due to cyber-attacks as those in 2007).

Data Embassy is defined as a ''physical or virtual data center an an allied foreign country that stores data critical government information systems and mirrors of critical service applications.''

The initiative comprises the following security measures: digital and data continuity (backup), data integrity (non-repudiation) and core government services an the event of a physical or cyber emergency. Three complementary parts accompanied this initiative:

- the Government Operated Cloud Solution, consisting of the maintenance of data backups and e-government services within Estonia's physical borders;

- the Physical Data Embassy Solution, which are backups located at physical Estonian embassies or allocated data centres created in allied countries that were chosen by the government. Therefore, the server resources are under the Estonian government's management and control, but situated outside the country's physical borders;

-the Virtual Data Embassy Solution, where backups of non-sensitive data are preserved in private companies' public cloud.

[ES10] Data Boxes MetaPosta website

Under the names “Electronic Post Box”, “Safe electronic box” and “Certified e-mail”, a large number of digital services, designed to take on the same role in the electronic world as the traditional mailbox, are currently in operation throughout the world. In addition to receiving documents, electronic strongbox systems offer members of the public and businesses safe, permanent storage services for valuable documents that they wish to store in their own personal space.

Over recent years, virtually every country in Europe has begun to operate public, private or mixed strongbox systems. The importance of these systems as High Impact Services, as the driving force behind the Information Society and eGovernment or as supports for sector applications, is on the increase and as key enablers of technological resources such as digital identity, electronic signature services and inter-operability between applications. As promoter of the METAPOSTA system, the Department for Economic Development and Competitiveness of the Basque Government is interested in examining the international development of Internet Safe Boxes and Strongboxes and as a result intends to organise an International Conference with the aim of reviewing a selection of European systems, study.

[EU25] MT@EC Machine Translation Service

Machine Translation Service is the action 2.8 of the ISA Programme.


Documents used by the European Commission, other European Institutions and public administrations in the multilingual environment of the European Union need to be available in different national languages. The sheer volume of content makes this an impossible task to achieve using human translators alone.


The European Commission provided a machine translation service for a number of years, based on "rule-based" Machine Translation technology. The service delivered a certain level of automated "raw machine translation" quality for a small number

of language pairs.

[EU26] European Commission Authentication Service (ECAS)

The European Commission Authentication Service (ECAS) is the European Commission's user authentication service. It allows authorised users to access a wide range of Commission information systems, using a single username and password.

The personalised access is based on an account for each user (physical person). Therefore in order to access the different services mentioned above, users have to login first via their ECAS accounts.


Creation of the ECAS account is possible from the Participant Portal. The unique identifier for a physical person in ECAS is his/her e-mail address. Some of the services are accessible without ECAS registration: FP7 calls, FP7 documents, organisation search and information on the use of the Portal.

[EU29] GENIS ISA Action 1.11

GENIS designs, develops and implements services that will manage and support the exchange of information between Member States and the Commission within the State Aid Notification Process.

It is set up by reusing existing components, building blocks and services modules, in particular those developed by the actions "e-PRIOR – eProcurement platform" and "e-TrustEx – Trusted Exchange Platform".

The action will permit Member States to transmit data directly from their back-office systems to the EU Commission, thereby avoiding the manual encoding of data. GENIS covers the exchange of structured and unstructured data, notably:

- pre-notification and notification of State Aid measures by the Member States to the Commission;

- yearly revision of State Aid notifications (real expenditures) by the Member States;

- management of communication and workflows (documents, messages, mails) between the Commission and the Member States during the State Aid Notification Process.

Moreover, it will provide a service to adapt the IT systems dealing with Staid Aid notifications in case of changes in State Aid legislation.

To support interoperability, the GENIS action will implement open interfaces (e.g. web-services) for Member States to connect their back-offices with existing Commission systems. Owner ISA Action 1.11

[EU30] IMI

The Internal Market Information System (IMI) permits to be aware which rights people and businesses have to move around the European Economic Area for work, study, trade, etc.

[OS15] MoReq2010, Modular Requirements for Records Systems
The MoReq2 specification is intended for users and suppliers of electronic records management systems and services, and educators. Its main intended usages are to serve as a basis for invitations to tender (also known as requests for proposal) and as a framework to guide development of new electronic records management systems. It can also be used to provide a basis for auditing existing electronic records management systems or services, and as a resource for academic or commercial trainers. MoReq2 is designed specifically to be an evolutionary upgrade of MoReq1. In addition to specifying functional requirements for a good, generic, electronic records management system it includes:

- Non-functional requirements.

- 13 “optional modules”, each of which defines requirements for a set of features that are often required in tight integration to electronic records management, such as document management (thus providing the basis of a specification for an Electronic Document and Records Management System), fax, collaborative working environment, and content management.

- A metadata model that defines 345 metadata elements needed to support the functionality defined in the functional requirements.

- Testing documentation (test data, test conditions, expected results, instructions) to allow compliance testing.

- An xml schema consistent with the metadata model.

- Explanatory text, appendices and references.

In addition the MoReq2 structure allows for countries to develop country-specific, language-specific, or region-specific “Chapters Zero” that take account of linguistic differences, national and regional legislation, national standards etc.

[RN12] Digital Certificates (X.509 standard)
Each user of ECRN Service owns two digital certificates of different typologies:

- The “authentication certificate” is used for recognizing the suer when accesses the web application. This identification allows checking the user’s right to use the application and to retrieve the connected role to control which specific functions  he/she can use and which data he/she can look at.

- The “signature certificate” is used by the user to digitally sign the documents he/she manages. Thanks to this signature, the ECRN platform guarantees the security of the documents (protection and integrity) and the security of their origin, in terms of who has signed and sent the document (non-repudiability).

Both the typology of a digital certificates are allocated on the same physical support that can be a smartcard or a USB token. The first one requires a smartcard reader connected to a PC USB port and the second one can be directly inserted in a PC USB port.
