AuthorityFile

An AuthorityFile is a listing of synonymous terms that singles out one of the synonyms as a canonical or preferred term.

For example, if you want to tell your software "when someone searches for 'Elizabeth Fortensky', instead do a search for Elizabeth Taylor", then you are essentially saying two things:

  1. 'Elizabeth Fortensky' is synonymous with 'Elizabeth Taylor'
  2. Out of these two choices, we're standardizing on "Elizabeth Taylor"

A data structure that says this sort of thing is called an AuthorityFile. If you only said #1, without specifying which synonym is canonical, then it would be a SynonymRing.

If you have a set of synonyms and one synonym has been singled out as the "preferred term", then the other synonyms are called variant terms.
