Product number: 6 Product name: Vocabulary Services Product description Vocabulary services to support NDG metadata schema and portals.

Product purpose To provide dictionary services to support both metadata creators and portals. In the former case, to help choose appropriate terms, in the latter, to ensure that user queries are matched not only exactly but also to possible terms that are narrower than the user query. Product Components

  1. Vocabulary Server: provides definitions in xml given a parameter query.
  2. Term Server: provides ontological matches given a parameter query and a scope (e.g. narrower, broader).
