All the data is in RDF and it's stored in a triple store (we use Sesame, 
Warning: LGPL) and presented with Velocity templates and full text 
search powered by Lucene. The code is available at


and it's BSD-licensed.

I find it the most powerful to use a special view with faceted browsing 
functionality, for example


the application is fully RESTful, no cookie or session is used (which is 
why the URLs are so big) but makes it very handy for bookmarking or for 
exporting. For example, the (undocumented) way to get the data out is to 
change the command=browse into command=export as in


which will give you the RDF formatted as RDF/XML.

If you want to know more, I'll be very happy to follow up privately or 
you are welcome to subscribe to the general@simile.mit.edu mailing list 
and ask your questions there.
