What Is IMS Vocabulary Definition Exchange For?
VDEX was designed to supplement other IMS specifications and the IEEE LOM standard by giving additional semantic control to tool developers. IMS VDEX could be used for the following purposes. It is used in practice for other purposes as well.
- Interfaces providing pre-defined choices – providing radio buttons and drop-down menus for interfaces such as metadata editors or a repository browse tool, based on the vocabulary allowed in the metadata profile used
- Distributing vocabularies among many users – achieved by simple XML file sharing, or possibly a searchable repository or registry of vocabularies
- XML stylesheets used to select and generate different views – selecting an overview of an entire vocabulary as an HTML or PDF file, for example; providing scope notes for catalogues; or storing a glossary of terms which are called upon by hyperlinks within a document
- Validation of metadata instances – validated against an application profile, by comparison of the vocabulary terms used in certain metadata elements with those of the machine readable version of the vocabularies specified by the application profile.
- Controlled terms for other IMS specifications and IEEE LOM – both may contain elements where controlled terms should be used. These elements are often specified as being of a vocabulary data type, and a definition of the permitted terms and their usage may be expressed using VDEX.

Famous quotes containing the words vocabulary and/or definition:
“[T]here is no breaking out of the intentional vocabulary by explaining its members in other terms.”
—Willard Van Orman Quine (b. 1908)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
