Dear ERC/Kernel Metadata Working Group,

You've all waited patiently for this group to begin its work, and I hope
you'll find your patience rewarded.  Some time ago I asked you all for
prioritized issues lists.  I merged those lists, acted on some items,
and now return with a proposed work plan and call for volunteers.
(To unsubscribe, visit http://www.jiscmail.ac.uk/lists/dc-kernel.html .)

** Draft Work Plan **

   1.  To do:  formally document kernel metadata, including the
       who | what | when | where elements, qualifiers, different values
       of "missing", and clarification of value syntax rules.

       * So far:  draft is now available at [1] for expansion and review.
       This is a key piece.  Please let me know if you're interested in
       joining a small subgroup to help with editorial responsibility.
       ( I've also attached this draft in case there's a procedural
       holdup in getting them onto the DCMI web site. )

   2.  To do:  define and implement a process for anyone to publish new
       vocabulary terms.  New terms will be marked as 'draft'.

       * So far:  initial process is to create an email message following
       the format described in [2] and submit via email; policy is that any
       conforming submission that passes the laugh test will be published.

   3.  To do:  define and maintain an ERC-equivalent external format
       based on XML and perhaps HTML/XHTML for the purpose of easy
       record exchange with other systems.

       * So far:  not started -- volunteers welcome.

   4.  To do:  add a "how" element, equivalent to DC Description.

       * So far:  done -- see [1].

   5.  To do:  create open-source software for manipulating kernel metadata.

       * So far:  sample Perl module at [3] available, but just the display
       and formatting stuff for now with some date normalization thrown in.
       As with any format, it's easier to dish it out than to interpret,
       so interpretation code is pending.  On the plus side, you can see
       this module in a production system by visiting any of the URLs:

           http://ark.cdlib.org/ark:/13030/tf0v19n804?
           http://ark.cdlib.org/ark:/13030/tf0n39n82v?
           http://ark.cdlib.org/ark:/13030/kt3489n8m4?

       Prototype ERC mappings are also viewable for biomedical literature
       using PubMed identifiers (use "pm" plus id) as follows:

           http://ark.nlm.nih.gov/ark:/12025/pm10611131?
           http://ark.nlm.nih.gov/ark:/12025/pm15066887?

       Remove the question mark to access a described object, and double
       it to see a larger record.  Any such identifiers should return
       eye- and machine-readable ERC/Kernel metadata.

       * Wanted:  disciplined hackers to create growing test suites.

   6.  To do:  create best-practices for applying who | what | when | where
       to different object types, e.g.,

           erc/book:  author | title | pub. year | ISBN or URL
           erc/photo:  photographer | caption | date taken | URL
           erc/map:  cartographer | region | mod. date | URL
           erc/article:  author | title | pub. date | article URL
                ( + in: journal name | volume / issue | journal URL )
           erc/painting:  artist | identifier | date created | URL
           erc/artifact:  discoverer | identifier | date found | URL
           erc/specimen:  discoverer | identifier | date found | URL
           erc/code:  programmer | title | mod. date | URL

       * Wanted:  subject and application area specialists to think through
         and debug foundation mappings of kernel elements in their areas.

I invite responses, additions, and changes to the proposed action plan.
The original ERC/Kernel paper is still found at [4].
