No subject

"Subject terms used in the interface are a subset of the Art and

I don't know the Getty AAT's relation to LC subject headings, but in most
image collections it's used exclusively.

Don't even try to build in time for that level of work. Buy or borrow
someone else's thesarus. It probably took about a zillion jillion
person-hours to develop the Getty.  Lucky others can use it!  We'd be
waiting a long, looong time for Flamenco if they'd have had to reinvent tha=
