A potentially very large source of lots of Linked Data in lightweight RDF(S) comes from various social networking sites who are increasingly making their data available in these formats (see Blog post from 18 Jan). The SIOC vocabulary is aiming to be for community sites (weblogs, message boards, wikis, etc.) what FOAF is for individuals: a lighweight vocabulary to enable linking and reasoning.

Folk with lots of SIOC data might be potential early adopters of LarKC-like technologies.  Note also that SIOC is one of the recommended vocabularies by Yahoo!’s SearchMonkey.

Incidentally, SIOC can also be seen as a response to Naso’s comment on the 18 Jan Post). He said that most semantics on social networks would “only” be in the form of learning techniques on top of a graph with little/no semantics. The SIOC approach is an attempt to encode real explicit symbolic semantics in this domain.

There is also a very neat 3D SIOC visualiation, at http://sioc.me/ (although I’m not alltogether sure how well this visualiation would serve me, it certainly looks cool). I wonder how well this can be adopted to other RDF graphs, and how much reasoning is going on while generating the visualisation? Any LarKC challenges there?
