Interoperability Architecture Solutions: Building bridges for digital
public services
Interoperability is the backbone of Europe’s digital transformation.
It enables public administrations, businesses, and citizens to
interact seamlessly across borders and sectors. At the heart of this
effort lies the European Interoperability Reference Architecture
[https://interoperable-europe.ec.europa.eu/collection/european-interoperability-reference-architecture-eira]
(EIRA), a blueprint which is designed to guide the creation of
interoperable digital public services.

The EIRA is a reference architecture developed under the ISA programme
and is now maintained by the Digital Europe Programme
[https://commission.europa.eu/funding-tenders/find-funding/eu-funding-programmes/digital-europe-programme_en].
This provides a common terminology for architects and developers to
use, as well as a set of Architecture Building Blocks (ABB) which
align with the European Interoperability Framework
[https://ec.europa.eu/isa2/eif_en/] (EIF). The EIRA was created to
help guide public administrations in producing interoperable European
Digital Public Services for businesses and citizens across Europe. The
newest release, known as EIRA v6.1.0, introduces improved views,
updated ABB documentation, and enhanced alignment with the latest EIF.

Interoperability architecture solutions like EIRA go beyond technical
alignment, also enabling open data ecosystems. By providing
standardised building blocks and semantic models, EIRA ensures that
data published by public administrations is discoverable, reusable,
and interoperable across borders. This synergy helps support the
European Data Portal to help fuel innovation and transparency using
open data.
