What's New

Version 6.4:

Core Database Engine:

  • Additional support for SPARQL 1.1 Functions, Update, WITH, USING, NAMED and Macro Library syntax.
  • Support for SELECT scalar_expression subqueries without FROM clause to avoid extra lock on fake subqueries.
Virtual Database:
  • Support for R2RML for generating Linked Data Views over ODBC- or ODBC-Bridge-accessible data sources and/or native Virtuoso RDBMS data.
  • Linked Data Views wizard includes option for importing and exporting R2RML scripts
  • Tighter integration of SQL and Linked Data such that any Web resource (be it LOD cloud or beyond) is now a bona fide ODBC, JDBC, ADO.NET, OLE-DB, or XMLA accessible data source accessible to any compliant application across Windows, Mac OS X, Linux, FreeBSD, Solaris, and many other Unix variants.
  • ODBC, JDBC, ADO.NET, OLE-DB, and XMLA access to SPARQL SELECT, DESCRIBE, and CONSTRUCT queries
  • ODBC, JDBC, ADO.NET, OLE-DB, and XMLA access to SPARQL SELECT, DESCRIBE, and CONSTRUCT queries
  • SPARQL virtualization via SPARQL-FED that deductively understands non Virtuoso SPARQL endpoints
  • SPARQL endpoint description graph for all Virtuoso SPARQL endpoints
  • SPARQL Graph Update protocol which provides another RESTful interface to Virtuoso's quad store.
Linked Data Middleware ("Sponger"):
  • New extractor cartridges (linked data drivers) for LinkedInGoogle+, StackOverflow, Disqus, Wolfram Alpha, Yahoo! Weather, and many others.
  • New NLP oriented meta-cartridges for DBpedia Spotlight, Yahoo! Content Analysis, Alchemy API, Pingar, and many others
  • Post-processing script for generating owl:sameAs links for co-reference resolution.
Security & Access Control:
  • WebID authentication and verification protocol integration into SQL DBMS realm such that SQL user accounts can now be associated with WebIDs. Net effect, Virtuoso's lower level SQL access for row level and label security now leverage basic or advanced ACLs via SPARQL.
New Client & Server Protocols:
  • CalDAV support enabling a Virtuoso instance act as a server to CalDAV clients (e.g., iPad, iPhone, and other devices) with regards to calendar data access and management.
  • CardDAV support enabling a Virtuoso instance act as a server to CardDAV clients (e.g., iPad, iPhone, Android, and other devices) with regards to AddressBook data access and management.
  • SyncML protocol update enabling a Virtuoso instance act as a server to SyncML clients (e.g., iPad, iPhone, Android, and other devices).
