This eLearning course aims to present how EIRA© and eGovERA© support Public Administrations in the analysis of a digital public service (DPS). EIRA© and eGovERA© are two solutions developed by the European Commission based on the European Interoperability Framework (EIF) that provide public policy support to European Public Administrations. One of the main use cases of EIRA© and eGovERA© is the analysis of the requirements of a DPS through the comprehensive views (legal, organizational, semantic, and technical), ensuring interoperability challenges are addressed.
