OpenAIRE Nexus - D3.1 Roadmap to semantic and technical interoperabilityv1.0

The aim of this deliverable is to draw the lines of action that will, in the first 13 months of the project, enhance the OpenAIRE-Nexus services to adhere to the EOSC Interoperability Framework (IF) recommendations, i.e. protocols, APIs, data model, exchange formats. At the time of writing the EOSC is still “in the making” and such recommendations are only partly established and in most cases under discussion by the community. Recommendations have been provided by several EOSC working groups, operating independently or jointly supported by the eInfraCentral, EOSC-Secretariat, EOSC-Hub, EOSC-Enhance, and OpenAIRE-Advance H2020 projects. The technical roadmap in OpenAIRE-Nexus will focus on the EOSC Core Interoperability Framework, making a distinction betweensemantic integration, i.e. adapting services and back-ends to recommended data models, concepts, vocabularies, and technical integration, i.e. adapting services to recommended APIs and data exchange formats
