Definitions, viewpoints and use cases

Purpose of this page

Every registry development is situated in a unique set of circumstances and thinking. This page is to be used to collect a few perspectives. These might include anything from statement of fact or position to formal use cases (see the Use Cases section on this page).


Anything from attributed quotes to structured description is fine on this page.

Definitions and viewpoints

"Vocabularies are sets of terms used to tag documents. Their use increases both precision and recall of searching. At the simplest level, all Flickr terms form a vocabulary. Richer vocabularies have semantics and structure. Thesauri, taxonomies, ontologies, authority lists and control lists are all more or less the same thing as vocabularies (purists will hate me for saying that). -- Mike Taylor on the Becta VMS

Use cases

"Two main ways to use a vocabulary: 1) Visible to the user. Can be browsed to find suitable search terms. 2) Behind the scenes: non-preferred terms mapped to preferred terms or synonyms expanded ... can include expansion to broader and narrower terms, or translated terms." -- Mike Taylor on the Becta VMS
