All the people are still there, and generally still in Bristol, if not
at ILRT (try buying beer in the Highbury Vaults!)

It did, but like most SemWeb stuff it's hidden "under the hood".

FOAF is RDF, so frees itself from XML concepts like "file". It's a
small problem to manipulate multiple entities in one document and a big
problem to manage one entity described across many documents. RDF tools
solve nearly all of this for you, and transparently. This is why it's
important to use something like Jena rather than document-based XML
tools.

The rest is just an exercise in web searching. Try identifying the
obvious author names, then tracking down their current projects.
