            Profile Support for the Atom Syndication Format
                      draft-wilde-atom-profile-02

Abstract

   The Atom syndication format is a generic XML format for representing
   collections.  Profiles are one way how Atom feeds can indicate that
   they support specific extensions.  To make this support visible on
   the media type level, this specification adds an optional "profile"
   media type parameter to the Atom media type.  This allows profiles to
   become visible at the media type level, so that servers as well as
   clients can indicate support for specific Atom profiles in
   conversations, for example when communicating via HTTP.  This
   specification updates RFC 4287 by adding the "profile" media type
   parameter to the application/atom+xml media type registration.

1.  Introduction

   The Atom Syndication Format "is an XML-based document format that
   describes lists of related information known as 'feeds'.  Feeds are
   composed of a number of items, known as 'entries', each with an
   extensible set of attached metadata.  For example, each entry has a
   title."  [1]

   Profiles "can be described as additional semantics that can be used
   to process a resource representation, such as constraints,
   conventions, extensions, or any other aspects that do not alter the
   basic media type semantics.  A profile MUST NOT change the semantics
   of the resource representation when processed without profile
