carrier vocabularies?

Anyone know of any good existing controlled vocabulary for ‘format’ or ‘carrier’ for multimedia materials?  I’m thinking of things like “CD”, “DVD”, “digital”, etc.

The closest I can get is from RDA at http://metadataregistry.org/concept/list/vocabulary_id/46.html (thanks Karen and Diane), but it seems _really_ insufficient. As far as I can tell “audio disc” is used for both a CD and a vinyl disc, and there’s nothing available there for “DVD” at all.   Or for “digital”. Although I’m not sure what I mean by “digital”, I guess CD and DVD are both digital, but I was thinking of something to identify a digital file on a computer network free of particular carrier. I guess that wouldn’t be in a carrier vocabulary at all, after all, that would be sort of a null carrier. Phew, this stuff does get complicated quick. Which I guess is why nobody’s worked out a good one yet.

Too bad RDA’s is so _far_ from good though. Any others anyone knows about?

( These days I’m pretty depressed about RDA).

    I’d be interested in your (depressing) thoughts about RDA : could you elaborate on this?

    Hi Jonathan,

    How about MIME types or Internet media types? Just a thought.

    Probably more than you’re looking for but I suggest you have a look at this: Green, Rebecca, and Nancy Fallgren. 2007. Anticipating new media: A faceted classification of material types. Conference Paper. June. http://dlist.sir.arizona.edu/1911/.

    Points out that content and carrier cannot often be explicitly separated as we have tended to act for quite a while now and seem to want to carry forward. Presents a faceted scheme to elucidate these ideas, which as you say, “get complicated quick[ly].” One big reason why is because we are attempting to delineate across unnatural, and sometimes non-existent, lines.
