At this stage, the draft has what I think is a fairly complete
section describing the historical context and rationale
for DCAM. It also provides a high-level overview of the
syntactic constructs specified in DCAM and explains how the
Description Set Profile language builds on the DCAM foundation.
The draft then focuses on three areas for which the relation
from DCAM to RDF constructs is unclear:
-- Description and Description Set, and their relationship to
emerging notions of Named Graphs.
-- The use of rdf:value for character-string "representations"
of a resource. Alternatives put forward include rdfs:label,
skos:prefLabel, skos:notation, foaf:name, and dcterms:title.
Is the DC-RDF default rdf:value too simplistic, even wrong?
Do we need a richer understanding of which predicate is
appropriate for which contexts?
-- The use of Vocabulary Encoding Schemes as opposed to SKOS
Concept Schemes (and the predicate dcam:memberOf as opposed
to skos:inScheme). Are the constructs equivalent? Should
DCMI de-emphasize the DCAM terms in favor of SKOS?
These sections will need to be fleshed out over the coming weeks.
The draft also has a placeholder section for more detailed
consideration of future scenarios for developing DCAM.
Should DCAM be abandoned (in favor of what)? Or should its
development be put on hold (de facto continuing the current
situation)? Or should work on DCAM be revived, whether under
the name "DCAM" or under a different name?
What would the impact of these courses of actions be on guidelines,
specifications, and messages that are based on DCAM?
