EIRA & eGovERA Specification

Welcome to the comprehensive documentation for the European Interoperability Reference Architecture (EIRA) and the eGovernment European Reference Architecture (eGovERA). This documentation provides detailed guidance on designing and implementing interoperable digital public services across the European public sector.
