rdflib

• Nice tutorial on XML.com. The rdflib documentation is, unfortunately, a bit spare.
• rdflib is a collection of Python modules that provide parsing, serializing, graph construction, storing, and some minimal query functionality
• It has little or no implementation of RDF's logical semantics, i.e., no consistency checking or entailment derivation
• It is extremely customizable: very easy to add new parsers, backends, etc., or to layer new functionality on top
• We will be using the 1.3.2 release. (Unless we pester the author to fix a bug or add a feature.)
• Feel free to pester the author to fix a bug or add a feature. His email address is eikeon@eikeon.com
