Hi, OpenLink Software is pleased to announce a new release of Virtuoso, Open-Source Edition, version 5.0.8. This version focuses on performance optimizations and speed enhancements: + SQL compiler is now re-entrant + Self-Join optimizations exposed at JDBC Driver level (as was already the case with ODBC) + SPARQL engine and SPARQL-BI extension optimizations have been merged + TriG serialization format for RDF is now supported alongside RDFa, N3, Turtle, and RDF/XML + Additional Sponger Cartridges for Digg, FriendFeed, and CrunchBase + Improved graph quality and fidelity from existing Cartridges (especially Freebase, eBay, Amazon, Google, Yahoo, and many others) + Improved handling of and bug fixes relating to the `OPTIONAL' SPARQL keyword + Self-Dereferencing fixes (e.g., Sponger was not properly de-referencing its own Proxy URIs) On the ODS front, the following have been addressed: + More flexible Mapping service model based on new OAT-based Mapping Control (which also includes a "province" locator) + Improved SyncML integration with Briefcase folders + Gem URL fixes for Atom, RSS, and RDF feeds For more details, see the release notes: <http://sourceforge.net/project/shownotes.php?group_id=161622&release_id=614029> Other links: Virtuoso Open Source Edition: + Home Page: <http://virtuoso.openlinksw.com/wiki/main/> + Download Page: <http://virtuoso.openlinksw.com/wiki/main/Main/VOSDownload> OpenLink Data Spaces: + Home Page: <http://virtuoso.openlinksw.com/wiki/main/Main/OdsIndex> + SPARQL Usage Examples (re.
