  • Triple Storage: storage abstraction layer to access third party RDF stores as well as its own Zend DB based RDF store
  • Storage Abstraction: two different interfaces for the storage abstraction: Zend DB and Virtuoso
  • Erfurt RDF Store: SPARQL to SQL rewriter and a corrsponding relational table layout
  • Caching: based on analysing the graph patterns of cached SPARQL queries in order to obtain information which updates will change the query result
  • More: Access Control, Versioning, SPARQL Query & Update, Plugins & Trigger, Datagathering & Data Wrapper
