ISA² - Interoperability solutions for public administrations, businesses and citizens



Semantic technologies boost the value of data by making it computer-friendly. They allow data to be accessed, linked, and automatically analysed by IT systems, thereby paving way for smart IT applications and artificial intelligence. The EU institutions, agencies and bodies are invited to reuse


Interview with Cristina Marco, Rafael Santisteban Responsible and Manuel Mata from Ciutat de les Arts i les Ciències (CACSA) - Generalitat Valenciana, Spain. 

Ciudad de las Artes y de las Ciencias (CACSA) has used our IMAPS solution to evaluate existing digital public services and the design of the “Sede Electrónica de CACSA”, an authentication portal and a catalogue of digital public services of CACSA. 


The Legal Interoperability team of the European Commission is on the mission to raise awareness, promote and share knowledge on digital-ready policies and the support of new technologies in policy activities and build the Better Regulation for Smoother Implementation (BLSI) community around those topics.

Interview with Cristina Cosma, Isa von Kalben and Ruben Narzul, programme managers of the Interoperability Unit of DG DIGIT.

The European Commission is currently evaluating the ISA² programme and the European Interoperability Framework to present a reinforced public sector interoperability policy. We have talked to three programme managers of the Interoperability Unit to learn more about shaping the new policy in a multidisciplinary team.

2020, what a year! Everyone in the Interoperability unit went through many challenges, both on professional and personal


Interview with Milagros Calvo Vergez (DG TAXUD) and Veerle Cumps (Secretariat-General) by Commission en direct (CEND), the Commission’s internal online magazine

EdiT, the European Commission instance of LEOS that will replace LegisWrite, was recently tested in Directorate-General for Taxation and Custom Union (DG TAXUD). CEND and LEOS team spoke to one its first users, policy officer Milagros Calvo Vergez (DG TAXUD), and to Veerle Cumps (Secretariat-General), who supported and guided all the Directorate-Generals (DGs) involved in this test phase.


Dr. Fotis Fitsilis, Head of the Department for Scientific Documentation and Supervision, Scientific Service of the Hellenic Parliament

LEOS is a free software tool that facilitates the editing/reviewing of legislative texts and generates legislation produced in an interoperable format. Dr. Fotis Fitsilis, member of the Scientific Service in the Hellenic Parliament, used LEOS to educate the future generations of public officials. 


Interview with Dr. Karmen Kern Pipan, Head of Data Management Department, and Tadej Gabrijel, Head of Electronic Services Development Department of Ministry of Public Administration, Republic of Slovenia

Karmen Kern Pipan and Tadej Gabrijel have used IMAPS for assessing one digital public service provided by the Slovenian Ministry of Public Administration. 


Interview with Pieter van Everdingen, Community Manager at Platform Linked Data Netherlands (PLDN)

Semantic interoperability is strongly connected to the concept of linked data, being one of its core components and allowing heterogenous data sources to connect via the Internet. In this interview, we discussed with Pieter van Everdingen, the Community Manager from Platform Linked Data Netherlands, which is an open network community of experts aiming to stimulate further adoption of linked data.



Interview with Peter Axelsson, BIM Strategist at the Swedish Transport Administration

Semantic interoperability is an area explored for a number of years. For the last decade, SEMIC plays a significant role by offering technical solutions widely adopted by a number of stakeholders. So far, all approaches were focused on how to implement semantic interoperability in public administrations, i.e., concentrating on providing government-to-government solutions, with less focus on the needs originated from the private sector.


Interview with Sebastiaan Taes, The Federal Service BUS at BOSA

The Federal Service Bus (FSB) of the Belgian Federal Public Service Policy and Support Directorate General Digital Transformation (FPS BOSA DT), wants to be the gateway to the most important (authentic) data sources of the Belgian federal government.


Alice Vasilescu, Community Manager for LEOS, external consultant European Commission, on behalf of the LEOS Team

A new version of LEOS, the open source software for legislation drafting, is available on Joinup. This third major release brings new features and improvements concerning version management, comparison view, structured annexes, templates configuration improvements and many more.

Tomas Sedivec

Interview with Tomáš Šedivec, Department of the Chief eGovernment Architect, Ministry of the Interior of the Czech Republic

Tomáš Šedivec has used IMAPS for assessing a number of digital public services provided by public administrations in the Czech Republic, such as the Czech Ministry of Health. He shared with us his IMAPS user experience and explained the benefits of IMAPS for his organisation.

Carlos Fernandez

Interview with Carlos Fernandez, Project Manager at Ministry of the Presidency, Relations with the Parliament and Democratic Memory, Spain

LEOS is a software tool helping those involved in drafting legislation, which is usually a complex process requiring efficient online collaboration. Comments, suggestions, version control, co-edition, everything is possible with LEOS. The software was released as open source and has developed a growing community around. One of the active community members and a user of LEOS is Carlos Fernandez from the Spanish Ministry of the Presidency, Relations with the Parliament and Democratic Memory.


Dr. Raul Abril, IMAPS Project Officer, Interoperability Unit, Directorate General for Informatics, European Commission

Today, the interoperability maturity of digital public services provided by EU public administrations scores on average at “essential” level. This means that the services implement the key interoperability aspects in a basic way: they use one digital channel, partial pre-filling or make a service catalogue publicly available. 

Benoît Origas

Benoît ORIGAS, Project / Programme / Service Manager, Team Leader, Data services Unit – Collaboration sector, Directorate General for Informatics, European Commission

EUSurvey is a secured platform for designing and conducting small to large online surveys. The service is multilingual, flexible and widely accessible for consulting stakeholders on a specific issue, conducting satisfaction surveys or collecting event registrations. EUSurvey is also the platform used for public consultations organised by the European Commission (see Have your say) allowing Europeans to have their voice in Commission initiatives.

Miguel Alvarez Rodriguez, Programme Manager, Interoperability Unit, DG Informatics, European Commission

Public service provision is at the centre of digital government. Citizens and businesses need to interact with public administrations in various personal or business situations from a birth certificate to pension benefits. To enable these interactions online, public authorities often develop portals or digital government information systems. In context of international collaboration and exchange of information, such models create interoperability issues with various consequences. To solve these issues, we defined a common metadata model Core Public Service Vocabulary Application Profile.

Open government data are a valuable source of information that is publicly available to anyone for analysis and reuse. However, even though governmental data are open, they are often represented and published in an unstructured way without following any specific guidelines. The ISA² Programme has developed a solution, e-Government Core Vocabularies, to help public administrations bring structure in their data. One of them is the Core Public Event Vocabulary (CPEV) that is a common data model for describing public events.
