Vocabulary Management Ambition: to collate, store and reference all major vocabularies and taxonomies Tools –Vocabulary Studio - editor –Vocabulary Bank - repository
Key Requirements To identify concepts and related terms To map between terms in different vocabularies via a spine Tag once, classify many times To support portals and tagging tools To support multiple curricula structures
A spine of concepts The basic items identified in the spine are concepts. They can represent ideas, things, learning objectives - or anything at all.
Some basics Each concept has a name, an identifier and some administrative information. It should also have a definition.
Terms Terms are words or phrases associated with a concept. There may be one or many.
Metadata With each term will be some information. Such as who submitted it, when, a local identifier, links to deprecated terms.
A bit of the spine Each part of the spine of concepts can be associated with a lot of information. There are expected to be at least 30,000 parts.
Views Most people will only see a vocabulary published in a Bank. This may have a structure, like a thesaurus. Nodes or facets are used just to make the structure.
A Framework There may be additional information associated with a structure, such as help text or associated curriculum outcomes.
A Topic Map The structure may have several kinds of relationships (associations) between parts.
Curriculum Map The additional information in a curriculum map could support navigation in tools or portals.
