In this case study CLARIN will integrate its DOG, the CLARIN Virtual Collection Registry and the Language Resource Switchboard with the EOSC MSCR, the EOSC DTR and the EOSC PIDMR in order to (i) make their functions and content available beyond the SSH Cluster borders to all EOSC users, (ii) benefit from the services and content (e.g. data types, crosswalks) available from other communities and infrastructures via the EOSC MSCR and DTR. Moreover, the integration with EOSC registries will make CLARIN domain language data resources available via the EOSC PIDGraph and the EOSC RDGraph. The CLARIN Virtual Collection Registry will indirectly benefit from this integration, relying on common PID frameworks, sharing of crosswalks and schemas.
