Material for discussion
DCMI does not approve vocabulary and encoding schemes, but acknowledges formally maintained schemes as suitable for use with DC metadata.
A registry of vocabulary and encoding schemes might be established and maintained by others (metadata registries; cf. the NKOS effort at http://nkos.slis.kent.edu/. The information DCMI needs fits in the proposed NKOS scheme.)
DCMI should try to agree with future maintainers of a vocabulary registry on data elements and definitions which guarantee that DCMI and metadata design needs are fulfilled. Vocabularies and encoding schemes registred there (if necessary with a specific indicator) would be "automatically" acknowledged for use in DC metadata.
In the meantime DCMI needs to establish a public list of acknowledged schemes. It might be appropriate to maintain separate lists for vocabulary qualifiers to the Subject element and for encoding schemes for use in the other elements. The Usage board creates the list proactively and adds to it on request. Relevant parts of the MARC code lists and schemes used in known metadata implementations are used to build an initial version. The public list page features a submission form where everyone can ask for acknowledgment of a scheme.
For each scheme the list should provide the following information:
Ex.: Getty Thesaurus of Geographic Names | TGN | http://www.getty.edu/research/tools/vocabulary/tgn/index.html | - |
Rules about what kind of schemes will be acknowledged
Rules about the naming of the schemes
Rules about the acronyms used as DCMI qualifier labels (?)
Rules about the specification of scheme versions
The Usage board acknowledges schemes after applying above rules by including them into the public list. That is the confirmation that they are appropriate for use in DC metadata.
