The CONNEG working group within the IETF has standardized a method for
registering media features. Broadly speaking, this is a way of
relating features like screen size, color depth, etc. to either user
agent capabilities or features of specific MIME objects. Please see
RFCs 2506, 2533, 2534, and draft-ietf-conneg-* for some of the current
work. This feature syntax is also being extensively used by the
Internet fax community; their work is documented in part by RFC 2530
and draft-ietf-fax-feature-T30-mapping-01.txt. All of this work has
also been submitted to ITU study group 8. James Rafferty, chair of
the FAX working group, and Dave Crocker would be able to provide
more information on that collaboration.
Within the W3C, the CC/PP group is working in this area; Johan Hjelm
has asked Graham Klyne and I to coordinate our work within the IETF
with their work. The first face to face meeting of that group is
September 23 & 24th; contact Johan for more information.
best regards,
Ted Hardie
