Dear all,
I'm forwarding this message in case any of you haven't seen the LC
NetDev and MARC Standards Office response to MARBI Discussion Paper 04.
While I can see a variety of reasons why this work may not meet the
needs of this Task Group, I do still think it best if we all stay
abreast of relevant efforts happening throughout the community.
The thread on the MARC listserv sited by Clay also includes replies from
Diane Hillmann and Karen Coyle.
Best,
-Corey

Hi list,
I'm forwarding the LC NetDev and MARC Standards Office's response to
DP04 pertaining to RDA. This has gone to the MARC listserv [1], but I
thought it might fit in well here too since this list is a bit more
centered toward digital library development and non-MARC metadata
efforts. It appears quite a bit of interesting discussion is beginning
to occur based on the responses that have gone public.

MARBI Discussion Paper 2008-DP04 concerning RDA notes that LCs Network
Development Office is working on the "3.1 RDA Media type, Carrier type,
Content type" issue. We are also looking into the other MARC
vocabularies as we have been developing a registry system that would
make our more complex vocabularies (e.g., languages, relators,
countries, GACs) and our simpler enumerated lists such as those found in
008 and 007 available in a structured form for reuse using semantic web
technologies. The registry entries would be URI identified and
retrievable via http. The information returned in response to a query
would be in a choice of syntaxes, including SKOS (the RDF label
vocabulary developed in the W3C for vocabulary-type lists), RDF/OWL, and
XML. The codes and terms would all be URI accessible and machine
actionable. We will be using the "info" namespace to identify the
entities in the registry. The complex vocabularies should be available
at least in SKOS by April or May for comment as the files are already in
XML.
One of the steps for the 007 and 008 value lists is to complete the
valuable work begun in Appendix 2 and align the MARC values with the RDA
values, which we are working on now. We will add the RDA/ONIX codes for
vocabulary items into the registry, where they apply, and other related
vocabulary terms where needed. Included in this effort will be many of
the controlled vocabularies used in MODS. We are targeting having these
ready before the June MARBI meetings as the mappings will be important
for the RDA proposals.
Related to this work are RDF/OWL representations and models for MODS and
MARC, which we are also developing. Several representations of MODS in
RDF/OWL, such as the one from the SIMILE project, have been made
available as part of various projects and we have found they useful for
our analysis and to inform our design process. We want to bring them
together into one easily downloaded and maintained RDF/OWL file for use
in community experimentation with RDF applications. Our time line is to
have the MODS RDF ready for community comment by June.
We think that the registry will be an asset in the evolution of MARC
into future configurations that have a greater separation of MARC syntax
from MARC data element set and look forward to working with the
community on these developments.
