OpenLink Data Spaces

Platform for Generating
Semantic Web Presence

What is Semantic Web Presence?

A place on the Web that exposes RDF Instance Data

What is a Data Space?

• A Data Container possessing the following characteristics:
  • Conceptual Data Model oriented (Containers, Item Types, Items, Relationships between Items)
  • No Logical Data Model Specificity (SQL, RDF, XML, Free Text etc.)
  • Inherently Heterogeneous
  • Exposes Data via Access Points
  • In the Eye of its beholder it may be perceived as a Database, Infobase, or Knowledgebase

Why Are Data Spaces Important?

• Expose Heterogeneous Data produced by Applications & Services such as:
  • Blogs & Wikis
    • Posts
    • Comments
    • Attachments
  • Shared Bookmarks
    • Topics
    • Tags
    • Links
  • Discussion Forums
    • Blog Comments
    • Wiki Talk Pages
  • Etc.

What is ODS?

A Platform for Creating Semantic Web Presence

	Courtesy - Dr. John Breslin (DERI)

How Do I Use ODS?

• You Create or Associate an ODS Instance (Desktop, Intranet, Extranet, Internet) with:
  • Weblogs (Meta Weblog, Moveable Type, Blogger, or Atom Publishing Protocol)
  • Wikis (those that support Atom Publishing Protocol)
  • Collections of Syndicated RSS(1.0/2.0)/Atom/OPML feeds
  • Shared Bookmarks (del.icio.us or local bookmark store)
  • Files residing on your desktop (via WebDAV based Briefcase)
  • Anything else in the Web 1.0 or 2.0 space accessible via HTTP and/or WebDAV

Some ODS Specific Features

• Upstreaming via Publising Protocols
  
• All Data is exposed via Shared Ontologies (SIOC, SKOS, AtomOWL, FOAF, Annotea Bookmarks, and more..)
  
• All Data is SPARQL Accessible
  
• In-build support for GRDDL and other mechanisms for generating RDF from non RDF Data Sources
  
• A lot more :-)
