OpenLink Data Spaces (ODS)

ODS is a new-generation Distributed Collaborative Application platform for creating presence in the semantic web via Data Spaces derived from Weblogs, Wikis, Feed Aggregators, Photo Galleries, Shared Bookmarks, Discussion Forums and more.

What are Data Spaces?

Data Spaces are a new database-management technology frontier that deals with the virtualization of heterogeneous data and data sources via a plethora of data-access protocols.

As Unified Data Stores, Data Spaces also provide solid foundation for the creation, processing and dissemination of knowledge, making them a natural foundation platform for the emerging Data-Web (Semantic Web, Layer 1).

Why are Data Spaces important?

They provide a cost-effective route for generating Semantic Web Presence from Web 2.0 and traditional Web data-sources, by delivering an atomic data container for RDF Instance Data derived from data hosted in Blogs, Wikis, Shared Bookmark Services, Discussion Forums, Web File Servers, Photo Galleries, etc.

Data Spaces enable direct and granular database-style interaction with Web Data.
