Unified Astronomy Thesaurus v.2.0.0 Release Notes

Version 2.0.0 of the Unified Astronomy Thesaurus consists of a polyhierarchy with 1843 concepts, 11 top concepts, a depth of 10 levels, with 320 related concept links.

Release Date: 1/31/2017

Overview of Changes

  • The UAT was switched from descriptive, human readable concept identifiers to numeric identifiers. This is a rather significant change, and included in the source code download for this version is a mapping from previous identifiers to new identifiers.
  • The preferred label of 79 concepts were updated to add context, clarity, and consistency.
  • 16 new concepts were added to the UAT.
  • 3 concepts were moved from one parent concept to another.
  • 9 concepts were merged into similar concepts to remove duplicates from the UAT.
  • Resolves Issues in Milestone Arinelle.
