Second ENDORSE 2021 follow-up event:

Linked Data Platforms in and across EU Member States

30 September, 14.00-17.00

Join via Webex:  

The next follow-up event of ENDORSE will take place on 30 September (14.00-17.00) as an online webinar of 3 presentations on Linked Data platforms in and across EU Member States.

The speakers will be:

Pieter van Everdingen: Platform Linked Data Netherlands, Innovation via meaningful connections

Platform Linked Data Netherlands (PLDN) is an open network community of linked data experts in the Netherlands, who would like to share their knowledge and experiences from the linked data projects they are involved in with everyone who has an interest in linked data and those that would like to get started with their own linked data activities. It has developed into a vibrant community with several hundred active members and a few thousand interested parties.

PLDN activities concentrate around organising networking events, facilitating activities for working groups and releasing publications on linked data topics, like the Gems of Linked Data Applications book (available in Dutch), which contains successful examples of linked data initiatives from our PLDN network that we would like to share with a larger audience. We are also very proud of a very different deliverable that we have created: Play-LOD, which is a card board game that can be used to explain the basic concepts of linked data in an easy to understand and playful way. And to make community members more hands-on with linked data, we stimulate them to experiment with linked data via our free to use PLDN lab environment for which we also organised a number of introduction courses. And we work with organisations in our network to start up new activities and new promising linked data initiatives that can possibly be financed or co-financed from innovation budgets and grants within the EU and the Netherlands. PLDN is completely open for any work co-operation that would lead to further adoption of linked data and more best practices.

Raf Buyle and Veronique Volders: Semantics at your fingertips - How Belgian municipalities create Linked Open data without additional effort

Jakub Klímek: Guaranteed and semantically interoperable public government data published and shared as Linked Open Data

In 2021, legislation was adopted in Czechia, introducing the obligation of public administration institutions to provide their public data as open data and, more importantly, to consume the open data whenever it is necessary to access the public data of another institution. Consequently, the Ministry of the Interior of the Czech Republic (MOI-CZ) introduced the so-called Public Data Space (PDS) and is currently working on the necessary infrastructure. It will consist of public data published as open data with additional guarantees ensuring the FAIR principles. The data in PDS will be cataloged in the National Open Data Catalog, along with all the other open data. In addition, the data providers will guarantee the formal correctness and availability of the data to the other institutions. To ensure the interoperability of the shared data, formal open standards (FOSes), as defined in EU DIRECTIVE 2019/1024, will be issued by MOI-CZ for the relevant data domains. A FOS prescribes the allowed data formats and data structures. At its core, it prescribes an RDF representation adhering to the principles of Linked Open Data. Other formats, such as JSON or CSV, can also be introduced if necessary, maintaining transformability to RDF through JSON-LD and CSV on the Web. The semantic interoperability in PDS will be achieved by mapping the data structures defined in FOSes to the public administration ontology, which we call the semantic government vocabulary (SGoV). SGoV defines important domain concepts, relationships between them, semantic mappings among concepts from different domains, and also the ISA Core Vocabularies. The FOSes themselves, including data structure definitions, their expression in different data formats, transformations between the formats, mapping to SGoV, and also documentation, will be generated from SGoV semi-automatically. A set of tools for the management of SGoV will be demonstrated in the talk. We will conclude with the possibility of extending our approach to the whole EU.


First ENDORSE 2021 follow-up event:

Personal Knowledge Graphs: why, what, and where to?

By Ivo Velitchkov, on 2 July (10.00 – 11.30, CET)

The market for Personal Knowledge Management (PKM) software boomed in the last 18 months. As in many other digital areas of accelerated growth, the pandemic served as a catalyst, but the trend was evident before that. And unlike the previous generation of PKM tools, the most successful ones in this wave manage the data as knowledge graphs. Personal Knowledge Graphs (PKG) fundamentally change the way we manage our information, currently trapped in emails, documents, presentations, notebooks and social networks. Many PKG users report huge boost in both productivity and creativity.

This webinar will explore various PKG use cases from intelligent note-taking and project management to learning and research, what kind of capabilities that serve these use cases stabilize in this ecosystem and what could be the impact of PKG on collaborative knowledge management and the adoption of enterprise knowledge graphs.

It seems the role of Personal Knowledge Graphs will only grow in the coming years but the way graphs and applications interact is going to change, transforming the whole ecosystem.



The Publications Office of the European Union and the ISA² programme of the European Commission work together to create an opportunity to link expertise to tackle current and future issues in the fields of interoperability and knowledge management.

Both benefit from their central positions. As a provider and reference organisation for semantic assets, experience, knowledge and technology sharing (standardisation, reference data, semantic assets and technologies, consultancy, guidance and support) for EU and national public services, the Publications Office offers open access for all to a specialised website, EU Vocabularies, and builds on knowledge-sharing platforms such as GitHub and Joinup to promote toolchain building blocks. The ISA² Programme from its side supports the development of digital solutions that enable public administrations, businesses and citizens in Europe to benefit from interoperable cross-border and cross-sector public services.

The EuropeaN Data conference On Reference data and SEmantics


creates an opportunity to link expertise to tackle current and future issues in the fields of interoperability and knowledge management. It brings together a large audience made up of simple users, practitioners, experts, researchers and solution seekers and providers in EU institutions and agencies as well as in national public services and universities.

The very first ENDORSE edition took place from 16 to 19 March 2021. You can view the conference proceedings on the conference website or download a free copy here.

The Publications Office of the European Union and the Interoperability unit of the DIGIT (European Commission) called for the creation of the ENDORSE exchange platform during the closing session of the ENDORSE 2021 event on 19 March 2021.

Our aim is to intensify the exchange of information between simple users, practitioners, experts, researchers and solution seekers and providers in EU institutions and agencies as well as in national public services and universities.
