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 termsTo map between terms in different vocabularies via a spineTag once, classify many timesTo support portals and tagging toolsTo 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.
