Simple Inference Service

I've uploaded the docs for the Simple Inference Service, so now you can play with Jena rules from the comfort of your browser window.

By way of an example here are some rules that infer some FOAF metadata, specifically that I know a bunch of people, using some basic data extracted from del.icio.us. Here are the results.

You can read the background to that experiment which was motivated in part by some thoughts I had on moving from lists to social content engines. In short, by adopting some standard tagging conventions in del.icio.us we can use its simple interface as a means to create rich metadata.

There's a lot of potential here, especially when you realise that you can tie together the results of the inference with the SPARQL query service to further manipulate that data.
