Maewyn,
Can you say a bit more about how I would _use_ PRONOM as an encoding
scheme in DC metadata please?
From the PRONOM Web site I can get information about products, and the
names/titles of formats, but if I want to say unambiguously that my
document has a format with the name/title "Microsoft Word 3.0 for MS-DOS
document", what value do I supply for the dc:format element? That string
as a literal value? Or some other token? Will PRONOM assign persistent
URIs for each format?
Thanks
Pete

Another alternative to MIME types in the National Archives PRONOM list,
which is available at http://www.records.pro.gov.uk/PRONOM/default.htm.
It is "a resource for anyone requiring impartial and definitive
technical information about the file formats used to store electronic
records, and the software products that are required to create, render,
or migrate these formats".

Greg,
I suspect that the reason you have not received feedback is that the
DCMI
activity is much more about the data elements and related schemas and
profiles than about encoding schemes and controlled vocabularies that
might be used to populate the elements as values.
As Misha has pointed out, there is a process for registering MIME
types.,
(now more properly called Internet Media Types) through IANA. However,
many file formats are not intended for transmission over the web or as
e-mail attachments and may not be in scope. There are other efforts
afoot
to identify and characterize formats at a much finer level of
granularity
(and register associated documentation for the purpose of "preserving"
them). The one I am familiar with is the proposed Global Digital Format
Registry. See http://hul.harvard.edu/gdfr/. However, this is still a
proposal, with some sponsorship for planning from the Digital Library
Federation and interest from many archival institutions, including LC.
DC is primarily for discovery, and it's not obvious to me that a lot of
people will be searching for stereolithography files. Is it essential
for
you to include a value for Format in your records? I am conscious of
lots
of DC records in various contexts that have no value for Format. If
there
are local reasons for including a value, perhaps a locally coined term
would be adequate.

PS I have another reason for responding. I am actually working on the
challenge of compiling information about digital formats so that
archival
insitutions can fulfill their mission to keep content usable despite
technologucal changes. Are the stereolithography files you are dealing
with in a format that is used for exchange in a particular community?
If
so, perhaps you could send me pointers off this list -- to [log in to unmask]
