Virtuoso 5.0.7 Release, Now With Jena and Sesame APIs

Improvements

  • Full operation with Jena and Sesame RDF Frameworks. This fully replaces any previous attempts at interop, and introduces samples and test suites.
  • Better support for alternate RDF indexing schemes
  • Parallel operation of the RDF Sponger, importing multiple sources concurrently.
  • New data formats supported for on-demand RDF-ization in the Sponger
  • More efficient support for inference of subclass and sub-property; now capable of efficiently handling taxonomies of tens of thousands of classes
  • OWL equivalentClass and equivalentProperty support.
  • Dynamic IRI host part support for mapped data and for metadata of local resources. Renaming the host or using multiple virtual hosts will accept URIs with the right host part and refer to the same thing, no duplicate storage required.
  • SPARQL optimizations for LIMIT and OFFSET
