                    The 'profile' Link Relation Type
                      draft-wilde-profile-link-03

Abstract

   This specification defines the 'profile' link relation type that
   allows resource representations to indicate that they are following
   one or more profiles.  A profile is defined to not alter the
   semantics of the resource representation itself, but to allow clients
   to learn about additional semantics (constraints, conventions,
   extensions) that are associated with the resource representation, in
   addition to those defined by the media type and possibly other
   mechanisms.

1.  Introduction

   One of the foundations of the Internet and Web Architecture is the
   fact that resource representations communicated through protocols
   such as SMTP or HTTP are labeled with a 'media type', which allows a
   client to understand at run time what 'type' of resource
   representation it is handling.  Sometimes, it would be useful for
   servers and clients to include additional information about the
   nature of the resource, so that a client understanding this
   additional information could react in a way specific to that
   specialization of the resource, where the specialization can be about
   constraints, conventions, extensions, or any other aspects that do
   not alter the basic media type semantics.  HTML 4 [HTML401] has such
   a mechanism built into the language, which is the 'profile' attribute
