Typefaces
During the early development of the TGDT, the establishment of a classificational
scheme for typefaces was considered but rejected; nonetheless, existing terms for classes of
typefaces have significant literary warrant and are included in the TGDT.
Typeface names are drawn from a variety of sources; only those typefaces that are
consistently named and that are believed to have the greatest significance have been
listed.
No particular convention of classification extensions for typeface identifiers is recom-
mended; users are urged to use the classification notation for
C.44.74.90 – followed by a plus sign (‘+’) and the name of the typeface in question.
Characters
The TGDT includes a number of characters in the Latin alphabet as topical terms. Other
characters that are not listed in the thesaurus may be assigned an identifier by appending
the qualifier ‘character’to the Unicode 4.1 character name. If the last word of the Unicode
name is ‘character’, no qualifier is added.
Only the first word of the character name, and any proper nouns that would normally
be capitalized in English usage, should be capitalized.
Classification notation extensions should take the form of the four- or five-digit
hexadecimal Unicode character code; the notation C.44.13.90 should be used as the base.
Examples
[Greek letter sampi (character) ] C.44.13.90+03E0
[Erase to the left (character) ] C.44.13.90+232B
[Linear B syllable B060 ra (character) ] C.44.13.90+10028Languages
Language identifiers may be constructed by taking the language’s primary name as given
in the SIL International Ethnologue,^1 with the qualifier ‘language’ added. If the word
‘language’ is already present in the language name, the qualifier is not added.
Identifiers for language families may be constructed using the language family name
as given in the Ethnologue plus the word ‘languages’, except that if the word ‘language’
already appears in the name of the language family, it is replaced by the word ‘languages’.
The pseudo-family ‘unclassified language(s)’ should not be used.
