Re: Next Gen Catalog and FRBR

Thanks, Ross, for the clarification on the use of URI (possibly in place
of authority file, though I have a reservation about the longevity of
URIs --not all will be persistent URIs and people do move around and who
will keep the info up to date, etc.).

I also forgot to point out that in the Ariadne article I sent out
earlier, although it's old, it has a good introduction to the concept I
used for teaching library school students, a valuable resource as
seminal as Tim Berners-Lee's article on semantic web.

At the end of the Ariadne article, there are a few references.
The link to Andy Powell's site has a good set of examples of RDF in xml:
http://www.ukoln.ac.uk/metadata/resources/rdf/examples/

OCLC Connexion Browser can also display records in the RDF model,
although it's a very crude slap of RDF on the whole description, so it
does not do any good in that sense.

So far the MIT lab seems to have a lot of interesting work with RDF
applications in the SIMILE Project mentioned to this list earlier.
And thanks for the info. on TALIS too.

Pandora.com- the music site may use this structure too, but I don't know
for sure.

I also know that Arizona State University is working on Fedora which has
the RDF architecture.
Here is the info. on Fedora and its use of RDF model with an example of
RDF in XML:

xt.html

Maybe someone at ASU can answer some questions you may have re: RDF and
library applications, Bernhard, or other readers of this list too.

Normally, I just lurk on this list, but I have some information I
thought to be useful to share. Its usefulness is in the eyes of the
readers.

Cheers,

Joy--

Bernhard,

Well, Richard's examples show the underlying RDF, but, at the end of
the day, it's still MARC in the background (or DC or whatever the
institution supplied).

The point, though, is the /potential/ of RDF, not the existing
practice in libraries.

See:
http://research.talis.com/2005/rdf-intro/

for how RDF works and how it could work for library data.

RDF allows us to use URIs to point to other data.  So, rather than
shoehorning everything we might need into one record (regardless of
whether or not it's the most appropriate format for that data), we can
disseminate the data over various records (say, authority, or holdings
or whatever new data or local data we want to include) without having
to shove it into the bibliographic record itself.  The use of URIs
give us absolute identifiers, so we're not matching on user entered
strings.

-Ross.
