InformationStore

RDFLib's InformationStore is a relational data store, or in other words, an RDF database. In particular, an InformationStore is a TripleStore with support for contexts.

InformationStore Interface

The InformationStore Interface extends the TripleStore interface. See the TripleStore documentation for a description of the TripleStore interface.

InformationStore overrides the following three methods from TripleStore to allow an optional context argument:

add(triple, context)

Adds triple, a tuple of the form (subject, predicate, object), to the InformationStore.

remove(triple, context)

Removes triple, a tuple of the form (subject, predicate, object), to the InformationStore.

triples(pattern, context)

A generator over all the triples in the InformationStore matching pattern. Pattern is a tuple of the form (subject, predicate, object) where each of subject, predicate and object are either specified or None to indicate any value will match.
