OpenLink Virtuoso Universal Server (Personal Edition)

OpenLink Virtuoso is a next-generation Universal Server Platform that facilitates the development and deployment of a new generation of Enterprise-wide, Internet, Intranet, and Extranet-based solutions, transcending prevalent enterprise challenge areas such as Disparate Databases & Data Sources, Web Service Composition, and Business Process Integration.

Virtuoso unravels the potential of the real-time enterprise without requiring you to "rip and replace" your existing IT infrastructure.

It enables the utilization of emerging application architecture models such as Service Oriented Architecture (SOA), Process Oriented Architecture (POA), and Event Driven Architecture (EDA) for your application development and systems integration projects.

Virtuoso will never compromise your choice of host operating system(s), database engine(s), or programming language(s), as you drive your enterprise towards realization of the real-time enterprise vision.

Virtuoso is a single-server solution that implements a plethora of industry standards. Grouped by logical functionality, these standards cover all areas of real-time enterprise technology foundation, including:

• Enterprise Data & Information Integration
  via a Virtual Database engine that provides a single XML, ODBC, JDBC, .NET, or OLE DB connection to heterogeneous data sources that includes all major database engines, HTML/XHTML, XML, Free Text, and Multimedia data.
• Semantic Content Production & Syndication
  through leveraging of built-in support for XSL-T, XML Schema, SQLX, XQuery, and XPath, which enables the transformation of heterogeneous data into a myriad of semantic data forms such as RSS, FOAF, RDF, and beyond.
• Service Composition
  by exposure of existing time-tested application logic for invocation using Web Services protocols without any code re-writes. Code format support includes SQL Stored Procedures, .NET assemblies, Java Classes, C/C++ modules, etc.
• Service Invocation Endpoints
  via HTTP/WebDAV based virtual directory and multi-homing functionality that provides endpoints for SOAP-, WS-Security-, WSDL-, and UDDI-compliant interactions with composite services.
• Process Orchestration
  by expression of application or solution behavior as a collective interaction across composite services, processes, and associated events.

Technical Architecture

Virtuoso's architecture covers the following realms of functionality:

• Web Services Platform

What is new in this release:

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.
