CLARIN's distributed network is made out of centres. There are several types of centres. The backbone of CLARIN is provided by technical centres, in particular Service Providing Centres or CLARIN B-Centres, for short. These units, often a university or an academic institute, offer the scientific community access to resources, services and knowledge on a sustainable basis. Therefore, there are strict criteria to become a CLARIN B-Centre: it should be based on a stable technical and institutional foundation. The Assessment Committee checks these requirements during an assessment procedure, while the technical coordination among the centres takes place in the Centre Committee.
Currently there are around 20 certified B-centres and several more centre candidates. This list is constantly growing, as new members are joining CLARIN ERIC. Information on all centres and their services can be found in the Centre Registry.
Other centre types are:
- C-Centres (Metadata Providing Centres, their metadata are integrated with CLARIN but they need not to offer any further services)
- K-Centres (Knowledge Centres, part of the CLARIN Knowledge Sharing Infrastructure)
- T-Centres (Trust Centres, providing access to protected resources via the Service Provider Federation)
- E-Centres (External Centres offering central services without being part of any national consortium)
Institutions in countries which are not part of CLARIN ERIC can become a CLARIN Centre of type C and K .
