Getty (couple of other details)

I also forgot a couple of other things:
The Getty vocabularies were created so that art historians could make
assertions about artifacts, using a standard ontology. TGN works in
a similar way to wordnet, having synsets (e.g. the concept of a
place, called different things at different points in time, and
having different spellings in different languages, although
annoyingly the spellings are not tied to a language code).
This from the Getty site:
1. Vocabularies can be used as "assistants" in database search
engines, creating a semantic network (or roadmap) that shows links
and paths between concepts. When querying a database, users can
follow these paths composed of synonyms, broader/narrower terms, and
related concepts to refine, expand, and enhance their searches and
achieve more meaningful results. When used as a search assistant, a
vocabulary is a powerful knowledge base -- linking searchers to
information from both structured and unstructured databases.
2. Vocabularies are sources of "standard terminology" for use in the
description, cataloging, or documentation of cultural heritage
collections. Vocabularies often reflect consensus of opinion within a
community, that is, by answering the question - "How do we talk (or
write) about this particular subject area?" In doing so, vocabularies
become valuable tools for professional catalogers and documentation
staff who need to establish consistent access points.
Also, there is a TGN key for each place, corresponding to Wordnet
SynsetIDs. For example, Leeds is 7019038. "The logical focus of TGN
is a place, information about which forms an intellectual record.
This intellectual record comprises all information tied to the place
through a unique numeric key (geog_key). Names, notes, coordinates,
dates, and place types for a place are linked by the geog_key."
Even if the data itself can't be licensed, could the TGN be used in
e.g. FOAF as a controlled vocabulary of places by referring to the
geog_key in RDF statements?
