Hi Giovanni!

Well, the problem is that we don't have an RDF dump, and it is quite
costly to generate one, due to the architecture driving the site
(classic MVC-style, driven by a SQL database). Basically, the simplest
way to do so would be to crawl the entire site, which brings us back
to my previous question (how to keep in sync the results of these
crawls) :-)

Same thing as for the RDF dump.

Although if we had an RDF dump, that would probably be a good way to
go. It may be a bit inefficient though, as it wouldn't take into
account the data that doesn't change?
