OpenLink unleashes latest edition of Virtuoso

A Semantic Web Technology-based solution for Enterprise Information & Data Integration

Burlington, MA. June 22, 2008 - OpenLink Software, Inc., announces the immediate availability of the latest edition of OpenLink Virtuoso, its industry-acclaimed hybrid data-server and integration platform for SQL, XML, RDF, and Web Services. This release introduces a new approach to enterprise information and data-integration, leveraging recent advances in Semantic Web technology and the best practices of HTTP-based Linked Data across heterogeneous data sources. The new release provides a platform for declaratively developing and deploying conceptual views of disparate enterprise data sources such as SQL databases, XML and RDF data sources, and SOA-based Web services.

Virtuoso enables end users, systems architects, systems integrators, and developers to interact with data at the conceptual as opposed to the traditional logical level. Data about customers, suppliers, invoices, orders, etc., stored in existing ODBC- or JDBC-accessible database systems such as Oracle, Informix, Ingres, SQL Server, Sybase, Progress, PostgreSQL, or MySQL, can easily be presented in RDF form for use in Semantic Web applications.

New Features

  • Meta Schema language for exposing SQL, XML, and Web Service data as RDF Linked Data
  • On-the-fly transformation of Web Services into RDF Linked Data
  • SPARQL Query Language support, facilitating powerful holistic views and traversal of enterprise data relationships
  • Transparent integration of SPARQL and SQL, such that SPARQL is executable from SQL via ODBC, JDBC, OLE-DB, or ADO.NET
  • Support for the SPARQL/Update (SPARUL) extension of SPARQL
  • Data-referencing across database instance, machine, and network boundaries
  • Use of HTTP/1.1 transparent content-negotiation for unobtrusive injection of RDF-based Linked Data, projecting existing infrastructure into the broader Semantic Web without disrupting ongoing activities.
  • Storage Providers for Jena, Sesame, Redland
  • Business Intelligence Extensions for SPARQL -- expressions in results, aggregates, grouping, and derived tables.
  • Significant enhancements to the inference support, enabling web-scale RDF support

Amazon EC2 instance now also available

Newly available is an OpenLink Data Spaces AMI (Amazon Machine Image), bundling the Virtuoso Universal Server, OpenLink Data Spaces (ODS), OpenLink Ajax Toolkit (OAT), and a collection of 3rd party applications (Wordpress, MediaWiki, phpBB3, and others). In moments, the ODS AMI delivers --

  • Point of presence on the Linked Data Web that meshes your Identity and your Data via URIs
  • SPARQL endpoint for SPARQL Protocol based access to your Data
  • (X)HTML based Interactive SPARQL Query Builder for SPARQL Query By Example
  • (X)HTML based Linked Data Browser/Viewer
  • System generated Social Network Profile & Contact Data via FOAF
  • System generated global Data Space overview via SIOC
  • System generated OpenID and automatic integration with FOAF
  • Transparent Integration with Facebook
  • Transparent integration with Amazon S3 for data backup and restore
  • Built-in support for SyncML, enabling data synchronization with Mobile Phones

Leadership via Innovative and Pragmatic use of Semantic Web Technology

"Effective combination of domain expertise with enterprise data-access and information-integration has been a challenging pursuit for organizations worldwide since the advent of the modern IT era," said Kingsley Idehen, Founder and CEO of OpenLink Software. "This release of Virtuoso introduces a new generation of Semantic Web technology innovation, leadership and pragmatism. Virtuoso delivers a technological solution that solves real business problems today - such as integrating data that is associated with a variety of disparate schemas, served by databases from a variety of vendors," he added.

Soeren Auer, of the DBpedia project, commented, "DBpedia provides a substrate for exposing knowledge buried in Wikipedia. Virtuoso enables us to serve the vast amount of DBpedia knowledge via Linked Data and SPARQL endpoints combining both performance and resilience."

Broad Operating System Support

The new release is available in 32- and 64-bit forms, for Windows, Linux, Mac OS X, FreeBSD, Solaris, IBM AIX, HP-UX, and other UNIX platforms.

Extensive Industry-Standard Support

Industry standards supported by Virtuoso include SQL, ODBC, JDBC, ADO.NET, OLE-DB, RDF, SPARQL, GData, XML, XQuery, XPath, XSLT, XMLA, WebDAV, HTTP, OpenID, NNTP, ATOM-Publishing and more.
