All No, this is not just DDC. The Universal Decimal Classification is considering releasing its top-level classes as linked data in the near future. I think (but don't quote me on it) that Library of Congress Classification will be available real soon now. You will be able to see a snapshot of available library-related linked data sets in the final report of the W3C Library Linked Data Incubator Group which is due in the next few weeks (the wiki is available athttp://www.w3.org/2005/Incubator/lld/wiki/Main_Page). Then there is the (in)famous Linking Open Data cloud which is expanding like a supernova ... (I notice it's just been updated again), available athttp://richard.cyganiak.de/2007/10/lod/Each blob in the LOD is an entire data set; the library ones are concentrated in the upper righthand corner. (Click on the diagram to zoom in, then click on a blob to go to the data set itself.) As others are implying, all this depends on using the classification and subject headings without local modification ... ... but it should be real easy, in the future, to add local schemes and modifications to the SW via open services like the Open Metadata Registry (http://metadataregistry.org/) - but then you have to link them to the standard schemes ...
