Until the Usage Board meeting in Bath in March 2004,
the issue "registration of encoding schemes" referred
to a process and tools for expediting the creation of
DCMI-maintained encoding schemes identified with URIs to be
maintained in accordance with the DCMI Namespace Policy.
An analysis of steps which would need to be undertaken
in order to put such a registry in place can be found at

In Bath, the Usage Board decided to consider an alternative
model: that of a very lightweight informational "registry"
of existing encoding schemes (i.e., of URIs usable as DCMI
Encoding Schemes). Tom was tasked with presenting this idea
to the Directorate for discussion.

As this registry would not involve the creation of new terms,
it would not be operated by the Usage Board, but by DCMI as
a whole.  

Putting into place even a lightweight registry, however, is
not a trivial undertaking. At a minimum, it would involve
the following tasks and commitments:

   1. Work with Harry to improve the interface and
       functionality of the Web-based
       registration tool [WEB-TOOL], see

   2. Update "Guidelines for registration of Vocabulary
       Encoding Schemes", see
       This document would need to explain what is means to
       have an existing URI, and what it means for that URI to
       be usable as a DCMI Encoding Scheme. This would need
       to be written up in simple, readable documentation.
       This explanatory text could be folded into the start
       page for the Web tool [WEB-TOOL], which currently
       provides user guidance on using the tool, which would
       require coordination with Harry on editing a single
       Web page. Or the information could be split out into
       a separate document -- whatever seems friendliest
       for users. Either way, we should ensure that all
       Web pages of relevance to the project of registering
       encoding schemes be fully cross-referenced with all
       of the other relevant Web pages.

   3. Clarify the process of vetting proposals:
       exactly who needs to do what to verify and evaluate
       a submission, what follow-up actions they need to
       take, what needs to be documented and where. Then,
       to document that process appropriately (see 3.1).

   4. Set up a JISCMAIL list to use as an
       archive of tasks undertaken for 2.2.

   5. Manage the project:

       -- coordinate and motivate the people who will
          check, evaluate, and approve submissions to the 
       -- make announcements to DC-GENERAL.

   6. Formulate a sustainable persistence policy for the 
       registry service.
