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 Chair, CONNEG > > Not that I'm aware of. > > I wish URIs had been used to identify user agents, but that's > water under the bridge, and a lot of it, by now. > > Oh!
