OpenLink Data Spaces, or ODS, is a suite of Virtuoso applications for creating and maintaining modern web-presence. It includes Social Networking, Weblog Platform, File Sharing, Wiki Platform, RSS 2.0, Atom 1.0, and RSS 1.1 Content-Aggregation Platform and more.

ODS has been developed to provide and a coherent nexus for Web-2.0 and the Semantic Web (also known as Data Web). All ODS application Data Spaces can be queried via Google's GData protocol. All Data Space front-end pages offer RSS 2.0, ATOM 1.0, and RSS 1.1 (RSS-RDF) content-syndication feeds, FOAF (for individual Data Space insights covering data and social networks), vCard, XBEL and other standard data-interchange formats where applicable.

ODS also offers browsing of application data via WebDAV, making your data-universe visible as a filesystem in the form of a URI-addressable and mountable tree (viewable via WebDAV-aware clients). A later release will add SPARQL access to application data.
