Tematres partial expansion of Thesaurus of Graphic Materials (Activities)
The image to the right is a screenshot of a partially expanded, but truncated (“A” to “D”), hierarchy of the first (of 26) main subdivisions of the Thesaurus of Graphic Materials (TGM), a controlled vocabulary for “indexing visual materials by subject and by genre/format.”‘ The subdivision is entitled ” Subject Terms Activities”. The image shows only the portion between A to the very beginning of D. This screenshot is not from official site of The Thesaurus for Graphic Materials (TGM), which is maintained under the aegis of the Library of Congress, as one might expect, because that version is user unfriendly in the extreme. Rather it is from a free vocabulary site, TemaTres Vocabulary Server which is much easier to navigate. That’s why it’s here, to give a meaningful sense of the TGM’s scope and contents.
As described on the official site:
“The Thesaurus for Graphic Materials is a tool for indexing visual materials by subject and by genre/format. The thesaurus includes more than 7,000 subject terms and 650 genre/format terms to index types of photographs, prints, design drawings, ephemera, and other pictures. In 2007, the subject and genre/format vocabularies, previously maintained separately, were merged into a single list and migrated to new software, MultiTes. Other minor changes are clarified in the links below. For questions about the thesaurus, contact TGM editors at: tgmed@loc.gov.”
In the overview of the TGM in the Tematres site the TGM is said to contain 11,893 terms, 13,262 relations between terms, and 5,230 non-preferred terms.
The merger of the subject and genre/format terms in a single thesaurus simplifies things in some respects but [click to continue…]
