OpenLink Virtuoso Universal Server (Personal Edition) specifications

Virtuoso 5.0, introduces a new approach to enterprise information and data-integration, leveraging recent advances in Semantic Web technology such as SPARQL 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, and orders, stored in existing ODBC- or JDBC-accessible database systems such as Oracle, Informix, Ingres, SQL Server, Sybase, Progress, and MySQL, can be presented in RDF form for use in Semantic Web applications.

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

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
• 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.
