Charter for 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.
