Centres of the type B, C and E:
- B is probably what most CLARIN centres will try to become. It is integrated into the infrastructure with all necessary building blocks: a stable repository with metadata, PIDs, -access for protected resources, a classification of its licenses based on the PUB/ACA/RES system, / descriptions for web services (next to the web service core model CMDI files).
- An E centre offers a service to other CLARIN centres but is not a part of the national CLARIN consortium.
The C centre is the bare minimum: a centre that has web-accessible resources that provides or CMDI metadata about these over .
