Stuff about Rich Boakes can be found at [1]

In 2002 Rich was working on the problem of combining information from incompatible resources when he wrote, then re-wrote, a library that turned into a graph manager. He didn't set out to do this, but the prototype and discovery process is an odd thing sometimes. Not wanting to have to maintain such a beast he looked around for prior art and was more than a little pleased to discover RDF.

Shortly afterwards Rich discovered that no matter who he was talking to, it was always easiest to describe the issues in terms of human analogy - consequently he talks a lot about FOAF.
