Method Details

len(self)
(Length operator)

Number of triples in the entire conjunctive graph

Overrides:: rdflib.Graph.Graph.__len__

add(self, (s, p, o))

Add the triple to the default context

Overrides:: rdflib.Graph.Graph.add

addN(self, quads)

Add a sequence of triple with context

Overrides:: rdflib.Graph.Graph.addN

context_id(self, uri, context_id=None)

URI#context

contexts(self, triple=None)

Iterate over all contexts in the graph

If triple is specified, iterate over all contexts the triple is in.

parse(self, source, publicID=None, format='xml', **args)

Parse source into Graph into it's own context (sub graph)

Format defaults to xml (AKA rdf/xml). The publicID argument is for specifying the logical URI for the case that it's different from the physical source URI. Returns the context into which the source was parsed. In the case of n3 it returns the root context.
