LIBRIS, the Swedish Union Catalogue, has for some time now been available as Linked Data. Examples, of which some may hurt your eye if looked at in a HTML-browser; never fear, in time they will become beautiful, and might even include a squiggly animation.

In a terminal window you can use curl to see the content negotioation in action:
curl --include --location --header accept:text/rdf+n3 http://libris.kb.se/resource/bib/5060570
We have used a mix of ontologies (FOAF, SKOS, Bibliontology, …), focusing on availability first rather than perfect representation of the underlying MARC-record. That comes later. The RDF also exposes some parts of our FRBR-algorithm, showing links between records believed to belong to the same work.
What we are working on right now is creating links to external datasets such as DBPedia/Wikipedia and between our own subject headings and to LCSH. This is pretty easily done once you have the data in RDF by the way.
As this is a work in (hopefully constant) progress, any input is appreciated. I will try to go into more detail later, until then I leave you with this picture.
Dear Martin & colleagues,
This is brilliant work. I cannot make any forecast as to when kb.dk will follow suit, in particular not when it comes to our OPAC which I’ve connections with. I’m thinking of how to deploy something similar when it comes to our digitization programs, cultural heritage heritage services, and e-science projects all of which I’m heavily involved in.
Yours
Sigge
