Terminology Services

This project provides Web-based services for controlled vocabularies.

Overview

Controlled vocabularies, such as thesauri and subject heading systems, provide representations of people, places, events, and concepts. Any subject of speech, writing, or visual depiction, may be represented in a controlled vocabulary and used to describe and access resources such as books, photographs, and web sites.

You are encouraged to experiment with the vocabularies and services provided by this project. The services may be used in a variety of ways. Some examples are:

  • as a source of terms for social tagging
  • for query refinement in search applications
  • to provide context for a search term
  • to validate names and subjects in metadata

Get Started

Visit the prototype to start building your own applications using Terminology Services. You can use the services to:

  • Search descriptions of controlled vocabularies
  • Search for terms/headings in a controlled vocabulary
  • Retrieve a single term/heading by its identifier
  • View relationships for a term/heading including equivalence, hierarchical, and associative
  • Retrieve terms/headings in multiple representations, such as HTML, MADS, MARC XML, SKOS, and Zthes.
