RDFLib is a pure Python package work working with `RDF `_. RDFLib contains most things you need to work with RDF, including:
* parsers and serializers for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, RDFa and Microdata.
* a Graph interface which can be backed by any one of a number of Store implementations.
* store implementations for in memory storage and persistent storage on top of the Berkeley DB.
* a SPARQL 1.1 implementation - supporting SPARQL 1.1 Queries and Update statements.

functional properties
A functional property is a property that can
have only one (unique) value y for each instance x, i.e. there
cannot be two distinct values y1 and y2 such that the pairs
(x,y1) and (x,y2) are both instances of this
property. -- http://www.w3.org/TR/owl-ref/#FunctionalProperty-def
graph
An RDF graph is a set of RDF triples. The set of nodes of an RDF graph
is the set of subjects and objects of triples in the graph.
named graph
Named Graphs is the idea that having multiple RDF graphs in a single
document/repository and naming them with URIs provides useful
additional functionality. -- http://www.w3.org/2004/03/trix/
transitivity
A property is transitive:
if whenever an element ``a`` is related to an element
``b``, and ``b`` is in turn related to an element ``c``,
then ``a`` is also related to ``c``. --
http://en.wikipedia.org/wiki/Transitive_relation
Standard examples include ``rdfs:subClassOf`` or greater-than
