RDF modules

  • querying, inserting, updating, and deleting RDF data.
  • defining namespaces for serialization purposes.
• Provides management interfaces for:
  • repository management, listing the available repositories provided by add-on modules hooking into the RDF API.
  • data management, allowing the conjunctive graph of the available RDF repositories to be queried using subject, predicate, and object.
  • namespace management, listing all URI abbreviations used for CURIEs.
• Provides theming functionality for:
  • property name-value tables from RDF data.
  • triple tables consisting of subject, predicate, object.
  • rendering URIs/literals in human-readable form (e.g. as CURIEs).
• Provides serialization/unserialization for the RDF/PHP and RDF/JSON formats.
