OpenLink Data Spaces (ODS) is a Distributed Collaborative Web Application Platform, Social Network, and Content Management System, written using VSP/VSPX and the OpenLink AJAX Toolkit atop OpenLink Virtuoso. It incorporates a broad range of industry standards for data access and data management.

[edit] What are Data Spaces?
A Data Space system is a multi-model data management system that manages data sourced from a variety of local or external sources. These sources may actually take the form of database management systems for a specific data model (relational, graph, tree etc.). The ODS Data Space platform identifies each unit of data via HTTP based Object identifiers (URIs) which enables it's data to mesh naturally with the emerging Giant Global Graph or Linked Data Web.
ODS is released as free software under the GNU General Public License.
[edit] Platform Requirements
- Virtuoso Universal Server as backend database and web application server.
[edit] OpenLink Data Space Functionality
ODS is an implementation of a Data Space platform that is based on the Virtuoso Universal Server, and follows the following philosophies:
- Data is in an Object Oriented form
- Every data object has a URIs which acts as an Object identifier
- All data within the internal data graph is internally and externally linkable due to compliance with Linked Data Web best practices
- All data is portable across other systems due to support of DataPortability standards and best practices.
ODS implements Data Spaces by providing:
- Social Networking
- Content Management
- Web Application Framework
- Installable internal applications, such as a Feed reader, an E-mail system, a Blog, a CRM System, Bookmarks System, a Calendar System
- Installable 3rd party components, such as MediaWiki, WordPress and Drupal
- Integration with other Social Networking and Web 2.0 Services, such as Facebook and del.icio.us
- Bridges across Web 1.0, 2.0 and 3.0 by exposing data in these realms as RDF based Linked Data.
The philosophies and implementations above, facilitate the development and deployment of, modern and open, distributed solutions that leverage Web architecture.
[edit] OpenLink Data Space Installations
There are a few options for using OpenLink Data Spaces:
- Download, install and configure on any server using Virtuoso
- Use an OpenLink hosting service
- Installation available on Amazon EC2
- Use the OpenLink online hosted service: Myopenlink.net
[edit] Technologies of OpenLink Data Spaces
Many standards and technologies have been implemented in ODS, including:
- W3C Standards, such as
- RDF and RDFS
- RDFa
- SPARQL
- OWL
- Meaning of a Tag (MOAT), Simple Knowledge Organisation Systems (SKOS) and Social Semantic Cloud of Tags (SCOT) for tagging
- HTTP and HTML Metadata
- DataPortability Recommendations, such as
- Other Standards, such as
- BPEL and other Web Services standards
- JSON and XML
- SIOC, FOAF and DOAP
- OpenSocial
