What is LOGD

Linked Data enables the provision of “data as a service” and conceives the Web as an open ecosystem where data owners, data publishers, and data consumers can interconnect and integrate disparate datasets. SEMIC explores the potential of Linked Open Government Data (LOGD), from a business and a technical point of view, as an enabler to the flexible integration of data coming from different e-Government systems.

The Study on Business Models for Linked Open Government Data - BM4LOGD identifies the number of enablers to the provision and reuse LOGD for public administrations:

  • The main driver for the use of LOGD is that it allows for flexible data integration; this helps to increase data quality by allowing cross-references to authoritative data to be included and may drive future development of new services.
  • The use of LOGD increases the efficiency of the internal operation of the data provider and allows them to fulfil their public task more effectively and efficiently.
  • LOGD is applied most successfully in reference data, such as in the case of the Named Authority Lists of the Publications Office, Eurovoc thesaurus and ESCO.
  • LOGD makes future upgrades of data models much easier, for example to include new data or connect data from different sources together.
  • URIs allow a ‘follow-your-nose’ navigation structure that provides better navigation through complex data.
  • LOGD is mostly provided free of charge and under open licences which enables further use and reuse of data.
  • Availability of guidelines and dissemination of best practices create common approaches and reduce risk in implementation by enabling organisations to learn from each other.

The ISA² programme has commissioned a number of studies as part of its Action 2.1 on semantic interoperability to provide further insight into issues relevant to semantic interoperability.

A state aid vocabulary for DG Competition to publish transparency information as open, machine-readable data

(December 2015)

This report provides an overview of an RDF dissemination vocabulary for State Aid Transparency data.



Towards a common policy for the management of persistent HTTP URIs by EU Institutions

(November 2014)

This report presents the ongoing work of an informal, inter-institutional Task Force on a common approach for the management of persistent, HTTP-based, Uniform Resource Identifiers (HTTP URIs) by EU institutions.

Report on high-value datasets from EU Institutions

(May 2014)

This report elaborates on a working definition of what "high-value dataset means". This can be used as a guideline for prioritising the publication of government datasets. The definition approaches the value of datasets both from the publisher's point of view, and the reuser's point of view.

Study on Business Models for Linked Open Government Data - BM4LOGD

(October 2013)

This report presents the outcome of a study on Linked Open Government Data (LOGD), a set of principles for publishing, linking and accessing open government data as a service on the Web.

Cookbook for translating Data Models to RDF Schema

(March 2013)

This cookbook provides guidance for the person who has the task of translating the Domain Model into an RDF schema.

How Linked Data is transforming e-Government

(March 2013)

This case study draws the link between Linked Data and eGovernment. It introduces Linked Data as an enabler of eGovernment transformation and summarises the initiatives of the ISA programme of the European Commission towards this direction.

10 Rules for persistent URIs

(March 2013)

This report documents a survey performed by ISA Action 1.1 on Semantic Interoperability in order to explore good practices on the publication of Uniform Resource Identifiers (URI), both in terms of format and of their design rules and management.


1. Linking public sector's organisational data

This pilot demonstrated the use of the Organization Ontology and the Core Location Vocabulary to describe the organigram of the Greek Ministry of Administrative Reform and eGovernance.

2. Qualification pilot Phase 2

This pilot demonstrates the application of the qualification process focusing on:

  • Distributed publishing of qualifications
    • Qualification publishing is a distributed process, involving several different stakeholders
  • Display annotated content
    • Allow full interoperability between the 3 pillars of ESCO
    • Annotate the qualifications with ESCO skills/competences
  • Demo: qpilot.semic.eu

3. Qualification pilot Phase 1

This pilot demonstrates the application of the qualification process focusing on:

  • Show the added value of the qualification metadata schema
    • Understanding the schema
    • Visualisation of the data
  • Enabling search on qualifications based on:
    • EQF
    • Subject area (ISCED-F 2013)
    • Country
    • Title
  • Demoqualifications.semic.eu


4. LOGD Pilot on visualising changes to legislation using ELI

In our legislation pilot, we demonstrated the possibility to transform legislative information into machine-readable data and ways to visualise legislation’s evolution over time.
