Google Base does have RSS 1.0 input, which is an RDF vocabulary (their
format is broken right now but they've suggested they're going to try
and fix it). Their input allows user-defined properties, which takes
this beyond RSS and closer to RDF proper. It's a little unconventional
in that the new terms appear in a Google namespace, and the input
syntax is constrained, but in essence it means they will be using RDF
pretty much as designed.

Yes, some machine-friendly route to the data would make a world of difference.

Implementation-wise, it seems like they've got something fairly RDF
triplestore-like behind the scenes, although apparently lacking things
like type inheritance etc that comes in RDFS. A month or two ago a
presentation appeared on the Web from one of the Google people (can't
find link, sorry) which described a database setup that was fairly
loosely-structured - I seem to remember every item had a datestamp.
Maybe that's what they're using. .

Ok, so their system isn't altogether Semantic Web-friendly, in that it
doen't (yet?) provide data out, but they've got it right as far as
using Semantic Web technologies to add value to an existing system.
