      Parameter purpose:

RFC 2425      MIME Content-Type for Directory Information September 1998


      Parameter values:

      Parameter special notes (optional):

      Intended usage: (one of COMMON, LIMITED USE or OBSOLETE)

   The explanation of what goes in each field in the template follows.

   Parameter name: The name of the parameter as it will appear in the
   text/directory MIME Content-Type.

   Parameter purpose: The purpose of the parameter (e.g., to represent
   the format of an image, type of a phone number, etc.). Give a short
   but clear description. If defining a general paramemter like "format"
   or "type" keep in mind that other applications might wish to extend
   its use.

   Parameter values: The list or description of values associated with
   the parameter.

   Parameter special notes: Any special notes about the parameter, how
   it is to be used, etc.

13.2.  Post the parameter definition

   The parameter description must be posted to the new parameter
   discussion list, [e-mail]

13.3.  Allow a comment period

   Discussion on the new parameter must be allowed to take place on the
   list for a minimum of two weeks. Consensus must be reached on the
   parameter before proceeding to step 4.

13.4.  Submit the parameter for approval

   Once the two-week comment period has elapsed, and the proposer is
   convinced consensus has been reached on the parameter, the
   registration application should be submitted to the Profile Reviewer
   for approval.  The Profile Reviewer is appointed by the Application
   Area Directors and can either accept or reject the parameter
   registration.  An accepted registration is passed on by the Profile
   Reviewer to the IANA for inclusion in the official IANA parameter
   registry. The registration can be rejected for any of the following
   reasons. 1) Insufficient comment period; 2) Consensus not reached; 3)
   Technical deficiencies raised on the list or elsewhere have not been
   addressed. The Profile Reviewer's decision to reject a profile can be
   appealed by the proposer to the IESG, or the objections raised can be

   addressed by the proposer and the parameter registration resubmitted.

14.  Parameter Change Control

   Existing parameters can be changed using the same process by which
   they were registered.

         Define the change

         Post the change

         Allow a comment period

         Submit the parameter for approval

   Note that the original author or any other interested party can
   propose a change to an existing parameter, but that such changes
   should only be proposed when there are serious omissions or errors in
   the published specification.  The Profile Reviewer can object to a
   change if it is not backwards compatible, but is not required to do
   so.

   Parameter definitions can never be deleted from the IANA registry,
   but parameters which are nolonger believed to be useful can be
   declared OBSOLETE by a change to their "intended use" field.

15.  Registration of new value types

   This section defines procedures by which new value types are
   registered with the IANA and made available to the Internet
   community. Note that non-IANA value types can be used by bilateral
   agreement, provided the associated value types names follow the "X-"
   convention defined above.

   The procedures defined here are designed to allow public comment and
   review of new value types, while posing only a small impediment to
   the definition of new value types.

   Registration of a new value types is accomplished by the following
   steps.

15.1.  Define the value type

   A value type is defined by completing the following template.

      To: [e-mail]
      Subject: Registration of text/directory MIME value type XXX

RFC 2425      MIME Content-Type for Directory Information September 1998


      value type name:

      value type purpose:

      value type format:

      value type special notes (optional):

      Intended usage: (one of COMMON, LIMITED USE or OBSOLETE)

   The explanation of what goes in each field in the template follows.

   value type name: The name of the value type as it will appear in the
   text/directory MIME Content-Type.

   value type purpose: The purpose of the value type.  Give a short but
   clear description.

   value type format: The definition of the format for the value,
   usually using ABNF grammar.

   value type special notes: Any special notes about the value type, how
   it is to be used, etc.

15.2.  Post the value type definition

   The value type description must be posted to the new value type
   discussion list, [e-mail]

15.3.  Allow a comment period

   Discussion on the new value type must be allowed to take place on the
   list for a minimum of two weeks.  Consensus must be reached before
   proceeding to step 4.

15.4.  Submit the value type for approval

   Once the two-week comment period has elapsed, and the proposer is
   convinced consensus has been reached on the value type, the
   registration application should be submitted to the Profile Reviewer
   for approval.  The Profile Reviewer is appointed by the Application
   Area Directors and can either accept or reject the value type
   registration.  An accepted registration should be passed on by the
   Profile Reviewer to the IANA for inclusion in the official IANA value
   type registry.  The registration can be rejected for any of the
   following reasons. 1) Insufficient comment period; 2) Consensus not
   reached; 3) Technical deficiencies raised on the list or elsewhere
   have not been addressed. The Profile Reviewer's decision to reject a

   profile can be appealed by the proposer to the IESG, or the
   objections raised can be addressed by the proposer and the value type
   registration resubmitted.

16.  Security Considerations

   Internet mail is subject to many well known security attacks,
   including monitoring, replay, and forgery. Care should be taken by
   any directory service in allowing information to leave the scope of
   the service itself, where any access controls can no longer be
   guaranteed.  Applications should also take care to display directory
   data in a "safe" environment (e.g., PostScript-valued types).

17.  Acknowledgements

   The registration procedures defined here were shamelessly lifted from
   the MIME registration RFC.

   The many valuable comments contributed by members of the IETF ASID
   working group are gratefully acknowledged, as are the contributions
   of the Versit Consortium. Chris Newman was especially helpful in
   navigating the intricacies of ABNF lore.
