OpenLink Virtuoso is a database engine that combines relational database functionality with RDF graph storage, SPARQL querying and web service capabilities.
The database supports SQL access to structured information alongside technologies used for linked data and semantic web applications. It can also provide access to information held in external data sources.
Virtuoso includes server functionality for exposing database contents through several protocols, allowing applications to work with relational records, RDF triples and other forms of structured information through a common platform.
This is free and open source software.
