John is right to be sceptical-

This is not what upward posting is supposed to be used for; in fact upward
posting is itself considered to be extremely poor form in Knowledge
Organization Systems. Even the SKOS primer notes this.

The Alternative Labels for a SKOS Concept fulfill the role of USE/USE FOR
relationships in traditional knowledge organization systems like thesauri.
 They are used to indicate different natural language strings that refer to
the same set of ``documents''.

This approach was used in the past if a document collection only had a few
books on rocks, and using the most specific headings would send the patron
scuttling between too many different file drawers.   I do not believe that
this is a good match for the desired use case.
