rdflib 7.1.4 — rdflib 7.1.4 documentation (original) (raw)

RDFLib is a pure Python package for working with RDF. It contains:

• Parsers & Serializers
  • for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, JSON-LD, HexTuples, RDFa and Microdata
• Store implementations
  • memory stores
  • persistent, on-disk stores, using databases such as BerkeleyDB
  • remote SPARQL endpoints
• Graph interface
  • to a single graph
  • or to multiple Named Graphs within a dataset
• SPARQL 1.1 implementation
  • both Queries and Updates are supported

Caution

RDFLib is designed to access arbitrary network and file resources, in some cases these are directly requested resources, in other cases they are indirectly referenced resources.

If you are using RDFLib to process untrusted documents or queries you should take measures to restrict file and network access.

For information on available security measures, see the RDFLibSecurity Considerationsdocumentation.
