Controlled vocabularies define the values that can be used for a given class or attribute (selected from a list of values in the input form when creating a record).
CCMM works with several such vocabularies.
Some vocabularies have been taken over, maintained, and updated by NTK. Wherever possible, these vocabularies were also adopted from other authorities, but certain modifications had to be made (in particular, assigning IRIs to individual items in the vocabulary, as required by the CCMM model). Some vocabularies are adopted from other authorities (COAR, IANA, and others) and cannot be modified (it is only possible to contact the respective authority to propose a change or a new value).

Controlled vocabularies managed by the NTK are displayed at vocabs.ccmm.cz. The SKOSMOS tool for vocabularies managing and presenting is implemented here, this tool enables user-friendly display of dictionaries and their export in RDF/XML or Turtle format.
These vocabularies are also available on GitHub in CSV format for download.
