One month ago I posted some questions to this list. But have received
(virtually) no reply. I am not sure why.
Perhaps I breached some unknown rule of etiquette. Perhaps these
questions have already well established answers. I suspect that
because I posted them with an "I am just a novice" preamble they were
not taken seriously.
I now repose them as "challenges" - all are intended seriously and
are based on the reports and working documents available on the web
site. Some may be due to my misunderstanding (1). Some arise from
what look like straight out errors in DC documents (4). Some have to
do with things that are missing from the DC picture (6). Some are
musings (7).
Responses keenly awaited.
1. why is the link to the information resource outside the metadata set?
2. if all elements in the metadata set are optional then is an empty
metadata set valid?
3. if format is defined by MIME Media Types then why do the list of
DC Resource Types substantially overlap with it?
4. how does the format relation type (isFormatOf and HasFormat)
relate to the DC element source (the definitions appear identical)?
5. if elements can occur any number of times why do none of the
examples in the Guidance on Expressing DC in RDF show this happening?
6. the OMG have developed the UML (& XMI) which supports the
definition of relationships between objects, how do DC relations fit
into that picture?
7. if I make a resource available am I the publisher? Thus if I place
a resource on the UCL web site it gains its authority from the fact
that it is located at that domain and hence UCL is the publisher
lending its imprimatur to my work, even though I made it available,
or have I misunderstood?
