I am grateful for the very useful information I got from
this group on the question of 'wrapping' digital objects.
The recent exchange on metadata extensions is a convenient
pretext to ask for advice once again.
At our institution, we are trying to address preservation of
and permanent access to 'born-digital' government information,
especially those produced by our provincial government.
This is a matter of some urgency, as we will have an election
in 6 to 12 months, and if there is a change of government,
large amounts of web-based information will disappear forever.
A particular problem we face is serials. Clearly, METS can
accomodate everything we need, however METS is not a viable
choice for now, due to the absence of tools. So, we are looking
to accomplish what we need with Dublin Core. What is needed
is something equivalent to MARC 856 -- issue/no. information and
a link to the file comprising that particular issue. Unfortunately
for our purposes, these are two different kinds of information, and
DC requires that they go into different tags (identifier and
I see two solutions: we could create an XML namespace to
accomodate our needs, but only at the price of interoperability.
Alternatively, we might well settle for a klunky, interim solution: an HTML
for each serial, with a link from the DC record, knowing we will
have to re-do all of it when a more satisfactory solution is available.
I find it surprising that this question has not come up in the DC
community -- but then work on DC originates in two sources, those looking to
access to web-based documents (esp. HTML) and the OAI-MHP
people. The latter are concerned with _article_ level metadata,
not aggregations like serials.
I broached this question on a couple of Dublin Core lists, without getting
So...my question is whether anyone knows of work on metadata
extensions that would accomodate these issues without going the
whole METS route.
