About the European Interoperability Reference Architecture

The European Interoperability Reference Architecture (EIRA©) is an architecture content metamodel defining the most salient architectural building blocks (ABBs) needed to build interoperable e-Government systems. The EIRA© provides a common terminology that can be used by people working for public administrations in various architecture and system development tasks. The EIRA© was created and is being maintained in the context of Action 2016.32 of the ISA² Programme. The EIRA uses (and extends) the ArchiMate language as a modelling notation and uses service orientation as an architectural style. 

EIRA v3.1.0

EIRA v3.0.0 was released on the 23rd of March 2019 after which the EIRA has been tested by writing Solution Architecture Templates and by modelling solutions at Member States. About one year later, version 3.1.0 of the EIRA has been released, containing significant upgrades related to the definition of its interoperability viewpoints, ABBs and related examples. The content of the release has been developed through an agile project management approach. Tickets from European Commission internal and external stakeholders have been analysed in order to address their feedback and requirements.

The new release includes now significant upgrades and can be considered the state-of-the-art in the interoperability domain.

In a nutshell: the major improvements of the new EIRA release

The new EIRA release contains many improvements compared to the previous 3.0.0 version such as:

• Revision of the architecture building blocks (ABBs) taking into account their relevance for EU integrated public services;
• Update of the Key Interoperability Enablers viewpoint to reflect the multidimensional nature of interoperability;
• Revision of the EIRA views and viewpoints;
• Migration of the EIRA Overview document to a Joinup page;
• Upgrade to ArchiMate® 3.1.0.
