Content Negotiation (conneg) ---------------------------- Charter Last Modified: 2000-10-05 Current Status: Concluded Working Group Chair(s): E. Hardie Applications Area Director(s): Ned Freed Patrik Faltstrom Applications Area Advisor: Patrik Faltstrom Editor(s): A. Mutz G. Klyne Mailing Lists: General Discussion:ietf-medfree@imc.org To Subscribe: ietf-medfree-request@imc.org In Body: subscribe Archive: http://www.imc.org/ietf-medfree/ Description of Working Group: A number of Internet application protocols need to indicate recipient capabilities, characteristics, and preferences when the resources they handle can vary in form. This working group will finalize registration procedures for distinguishing attributes which cause the media delivered to vary in form. The registration of these "media features" will provide a supplement to the MIME registration of media types and enable the development of a cross-protocol vocabulary for exchanging information on recipient capabilities, characteristics, and preferences. Since these distinguishing attributes commonly occur in related sets, this working group will also describe at least one method for referring to composite media feature sets. Experimental methods for using these features and feature sets within specific protocol contexts may be developed within this group or within the groups standardizing the relevant protocols. The working group is aware of applications which desire to negotiate what content is delivered as well as the form in which it is delivered. As much as possible, the group will endeavor to create a framework for exchange sturdy enough to handle the later addition of this type of negotiation. It will not, however, address this need directly nor will it limit its design choices based on the possible later addition of this negotiation. Goals and Milestones: Done Submission of W3C CCPP crosswalk to IESG for consideration as Informational Done Submit Revised version of Content-Features draft Done Submit Revised version of Composite Media Features Done Submission of Type feature registration to IESG for consideration as a Proposed Standard. Done Submission of Content-Features to IESG for consideration as a Proposed Standard. Done Submission of Composite Media to IESG for consideration as a Proposed Standard. Done Group enters FIN_WAIT Internet-Drafts: No Current Internet-Drafts.
