To help you look at the rdf store, copy and paste this query into the
spaql box:
(although I suppose this will get horribly word wrapped)
CONSTRUCT {
<http://talisbase.talis.com/freecat/manifestation/df93ff84c5e8966dfc4da1
d31a706856#self> ?p ?o .
?o ?p2 ?o2 .
?o2 <http://talisbase.talis.com/bibrdf#displayAs> ?o3 .
?o2 <http://talisbase.talis.com/bibrdf#seenAs> ?o3 .
}
WHERE
{
<http://talisbase.talis.com/freecat/manifestation/df93ff84c5e8966dfc4da1
d31a706856#self> ?p ?o .
OPTIONAL
{
?o ?p2 ?o2 .
OPTIONAL
{
?o2 <http://talisbase.talis.com/bibrdf#displayAs> ?o3 .
}
OPTIONAL
{
?o2 <http://talisbase.talis.com/bibrdf#seenAs> ?o3 .
}
}
}
Then you can see how we have structured some of the the RDF.

Subject: Re: [NGC4LIB] Trouble with FRBR/RDA
OK, I've been lurking for too long - somebody used the 'semantic'
word and I can't hold my tongue any longer!
As a company with 40 years heritage in this stuff and several years
building semantic web software we've been doing some of this already.
One of the projects I've been working on is about representing
bibliographic data in RDF and we've had some great success, both with
playing with the data and with the things it makes possible. We still
have a huge amount of work to do with this stuff and the links that
follow are very early prototypes, on which we welcome any feedback.
Firstly, we took some marc data (in this case some very dirty marc data
with lots and lots of duplicates and typos and stuff) and converted it
into RDF. Ideally we would use a public ontology for the RDF - and we're
looking to RDA for that, but for expediency in the prototype we've made
up our own. Second, we built a little tool to let you wander around the
data.
Here's that tool: http://tinyurl.com/23xh7o (this is prototype code, it
gets slower the longer it's been used, so be sure to shutdown your
browser every now and again). If you have a play with that you can see
that the data still has a lot of duplication in it. if you want to look
at the raw data, you can using a semantic web query language called
sparql at this url http://api.talis.com/stores/freecat-dev1/
services/sparql
We're very interested in feedback from all of you, but we're also well
aware that what we've done is far from ready. Feel free to discuss this
here, or email me off-list or whatever. Above all, tell us what you
think is wrong with the _idea_ that this work shows.
