Bonjour,
Sudoc [1], the French academic union catalogue maintained by ABES [2], has
just been released as linked open data.
10 million bibliographic records are now available as RDF/XML.
Examples for the Sudoc record whose internal id is 132133520 :
. Resource URI : http://www.sudoc.fr/132133520/id
. Generic document : http://www.sudoc.fr/132133520 (content negotiation is
supported)
. RDF/XML page : http://www.sudoc.fr/132133520.rdf
. HTML pages with schema.org microdata [3] for search engines :
http://www.sudoc.fr/132133520.html . The users are not supposed to visit
these microdata pages : they are redirected to the standard UI :
http://www.sudoc.abes.fr/xslt/DB=2.1/SRCH?IKT=12&TRM=132133520
Sudoc RDF data are linked to http://lexvo.org and http://dewey.info/ .
They are also linked to IdRef [4], ie the Sudoc authority file that ABES
considers as a separate and open application.
2 million IdRef records are also available as RDF data (since October 2010).
The links between Sudoc and IdRef are bidirectional.
For example, http://www.sudoc.fr/110404416/id ( Rethinking symbolism by Dan
Sperber ) links to D. Sperber's IdRef URI: http://www.idref.fr/027146030/id
.
But, in the other direction, http://www.idref.fr/027146030/id links to *all*
the Sudoc documents that are linked to this authority.
In next months, we hope to add more links to our data, to OCLC and BnF
resources among others.
More info (in French) here : http://punktokomo.abes.fr/
Congratulations, this is fantastic nes.
Hi Dan,
Thanks !
And I think also a very timely
test-case for how community-maintained and consortium-based standards
(schema.org) can be deployed alongside each other.
As this thread shows, this bi-face publishing of data is (legitimately)
controversial.
Someone has to experiment...
We'll see how it goes...
Could you say a little more about the subject classification aspects
of this data? I don't know a lot about French cataloguing. In the
sample URIs you give above, I find only Rameau. You mention also
Dewey.info, so I guess there's Dewey in there.
Here is an example with Dewey.info :
http://www.sudoc.fr/004471245.rdf
Some more in Sindice (http://dewey.info/class/330/):
http://sindice.com/search?q=http%3A%2F%2Fdewey.info%2Fclass%2F330%2F
And Rameau also has
some mappings to LCSH.
Rameau is maintained by BnF. [1]
Sudoc loads and uses a copy of Rameau.
IdRef [2], our application dedicated to authority data, publishes HTML
and RDF pages for Rameau :
Generic document : http://www.idref.fr/035798734
RDF document : http://www.idref.fr/035798734.rdf
<http://www.idref.fr/035798734>
We are eager to add owl:sameAs links to an official and up-to-date
Rameau-in-SKOS dataset. By now, such an official dataset does not exist,
despite Antoine Isaac's bright experimental work [3]. I hope it will. I
am sure it will (just my feeling) but i don't know when :)

[2] http://www.idref.fr

Are there other schemes?
I should have mentioned that we link to FMeSH as well. [4]
FMeSH is the French translation of MeSH.
Example Example Example :
http://www.idref.fr/040697916.rdf
This record links to http://purl.org/commons/record/mesh/D004454
But these MeSH PURLS seem to be experimental.
Are there official MeSH URIs maintained bu NLM (US National Library of
medecine) ?

e.g. I'm interested in
particular to find instance data for UDC and for Library of Congress
Classification (LCC), but also anything else that has a SKOS
Even if Rameau is preferred in our Sudoc context, we have many MARC
records containing UDC codes or LCC terms.
We should add this information in our RDF bibliographic data.
I hope it helps

expression.
Thanks for any more info,
cheers,

ps. some Gremlin examples follow (see
http://danbri.org/words/2011/05/10/675 ) ... it uses the Linked Data
Sail to pull in pages on demand from the Web, as you explore into the
graph.
g = new LinkedDataSailGraph(new MemoryStoreSailGraph())
i1 = g.v('http://www.sudoc.fr/132133520/id')
