Currently there are several ways to explore the UAT online; a hierarchical browse, an alphabetical browse, a sorting tool, and the API.
Browse Alphabetically: Scroll through an alphabetical list of terms in the UAT. Clicking on a specific term will bring up information, such as its broader, narrower, and related terms.
Browse the Hierarchy: This shows the thesaurus terms in context, and also lets you click in to see details on each term, such as scope notes and synonyms.
Download from GitHub: Download the source files for the UAT from GitHub. Each previous release has also been archived on GitHub, along with change notes.
UAT API: Provided by ANDS, this interface is optimized for extracting information about the UAT by scripts and programs.
