Together with the EIRA©, the eGovERA© is a key element within the Interoperability Architecture portfolio to support the interoperability of Digital Public Services across the European Union.

eGovERA© stands for eGovernment European Reference Architecture. It is a set of specifications (i.e., eGovERA© Foundation) and tools (e.g., eGovERA© Upscale) directly based on the EIRA©, which aim to help Public Administrations across Europe with additional and more granular reference architectures and tools to analyse and design Digital Public Services. With eGovERA©, Public Administrations have the guidance they need to create seamless, integrated services in line with EU-wide interoperability standards.

The main purpose of the eGovERA© is to provide a structured approach that helps European Public Administrations ensure that their Digital Services are interoperable, meaning they can easily exchange data across borders and sectors. To this end, eGovERA© Foundation provides additional granularity to EIRA© defining the most salient Architectural Building Blocks (ABBs) needed to build European interoperable solutions supporting public services in business agnostic and specific (i.e., Health, Customs, Taxes) domains.
