CLARIN's distributed network is made up of centres. There are several types of centres: B-centres, C-centres and K-centres, each offering different kinds of expertise and services.
B-Centres: Technical Centres
The backbone of CLARIN is provided by technical centres, known as 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.
Currently there are more than 20 certified B-centres and several more centre candidates. This list is constantly growing, as new members join CLARIN . Information on all B-centres and their services can be found in the Centre Registry.
C-Centres: Metadata Providing Centres
Their metadata are integrated with CLARIN, but they need not offer any further services.
K-Centres: Knowledge Centres
K-Centres share their knowledge and expertise on one or more aspects of the domain covered by the CLARIN infrastructure.
The focus of CLARIN is on language resources (in all modalities, from all regions and with any topical orientation) and K-centres serve researchers and educators from any discipline where language plays one of its many roles, ranging from object of study, a means of communication or expression, a means to store and extract information, object of learning or teaching activities, to training source for data-driven analytics, and many others. K-centres can be mostly found in CLARIN countries, but also exist elsewhere, and they all have a virtual presence.
