Vocabulary for the IVOA Unified Content Descriptors (Version 20081104, 2008-11-04)
type: ConceptScheme
created: 2008-11-04
creator: The IVOA Semantics Working Group
description: The UCD standard is an officially sanctioned and managed vocabulary of the IVOA. The normative document is a simple text file containing entries consisting of tokens (for example em.IR), a short description, and usage information (syntax codes which permit UCD tokens to be concatenated). The form of the tokens implies a natural hierarchy: 'em.IR.8-15um' is obviously a narrower term than 'em.IR', which in turn is narrower than 'em'. Given the structure of the UCD1+ vocabulary, the natural translation to SKOS consists of preferred labels equal to the original tokens (the UCD1 words include dashes and periods), vocabulary tokens based on them (for example, "emIR815Um" for 'em.IR.8-15um'), direct use of the definitions, and the syntax codes placed in usage documentation.
