7.5. WOFF 1.0

Macintosh Universal Type Identifier code: "org.w3c.woff"

Is this part of a media type registration? (If so, is it required for
all "font" subtypes?)
Chris Lilley: 

I opened an issue on Macintosh type codes:
https://github.com/svgeesus/ietf-justfont/issues/26

There are two Apple-specific systems: the old four-character Macintosh Type Codes mentioned in the Media Types registration template, which were in use up to Mac OS 9 but are no longer used, and the newer Universal Type Identifiers used in OS X.

I raised the issue of which to use (on media-types@ietf.org)

and got a swift response from Ned Freed suggesting that the legacy Macintosh Type Codes were of little value, and that adding the current Macintosh  UTI was probably beneficial.

In response, I checked all the  Macintosh Type Codes in the current document; they all say "(no code specified)" which seems optimal.

I also looked at the Apple documentation for UTIs. There are two forms, the 'public' ones defined by Apple and the extensible, java-style reverse DNS ones for other organisations.
https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/understanding_utis/understand_utis_conc/understand_utis_conc.html#//apple_ref/doc/uid/TP40001319-CH202-CHDHIJDE

There is a registry of the public ones, including font-related UTIs like public.truetype-font and so on
https://developer.apple.com/library/content/documentation/Miscellaneous/Reference/UTIRef/Articles/System-DeclaredUniformTypeIdentifiers.html#//apple_ref/doc/uid/TP40009259-SW1

I added these to the current document, so all font subtypes now have this information.

I have thus closed this issue.
