From a discussion on adding support for following redirections in the robot
we started talking about how to express the robot constraints as RDF.

What I would really like to do for the robot is to have the constraints
expressed as a blob of RDF where you can express more rich constraints
including under what circumstances to follow redirections, etc. etc.

As RDF uses XML, this ties into the integration of expat that I think Bob
Racko is working on - the rough initial version of this integration which I
provided still needs some work:


Has anyone written an RDF parser based on expat? Would anybody like to help
doing this?
