The blueprint reference architecture has been developed as part of the European Higher education Interoperability Framework within the European Digital Education Hub. It describes the technical aspects of the reference architecture as built in the open architecture modelling language ArchiMate. The architecture presents three complementary views for each of the eight priority use cases identified: organisational, semantic, and technical. Each view serves as a structured guide, enabling institutions to identify and evaluate their current set-up, thereby gaining insight into how their components in place interact with the recommended architectural blocks. This approach provides a tangible pathway for institutions to achieve an advanced level of interoperability.
