With the growing amount of information exchanges between public services (across borders and sectors), the need for interoperability in Europe is higher than ever. The ISA² Action 2.1 (EIA) introduced the European Interoperability Reference Architecture (EIRA) to guide public administrations in their work to provide interoperable European public services to businesses and citizens.
This document provides definitions of interoperability, explains its challenges in the context of European eGovernment and how the EIRA supports interoperability in the very specific context of providing European public services.
The content of this document relates mainly to enterprise architecture, having a background knowledge of matter is recommended in order to correctly understand it.
