OpenLink And The Social Data Web

Orri Erling - Program Manager, Virtuoso

OpenLink Data Spaces

• Instant Data Web point-of-presence in the cloud
• Define your profile and online content
• ODS gives you dereferenceable URIs, SPARQL end point, etc.
• Data junction box, RDF sink
• SPARQL and Web Services for query and UI extensibility
• http://community.linkeddata.org>

Most of Data Web is Social Centric

• N x10⁸ users, many have multiple profiles
• Web 2.0 scales by app-specific data structures, denormalization, HTML cashing, partitioning
• The Data Web cannot do this without destroying its flexibility
• Enable SPARQL + full-text query against the whole web social graph

Implications

• Simple vocabularies
• Minimal inference
• Minimal bNodes
• In the generic case, materializing entailment only works in app-specific DW
• For the open web, inference must be run-time

Next

• It's time to deploy applications
• Two-pronged approach
  • More scale in RDF stores
  • Agreement on discovery and description for federation
    • VOID - Vocabulary for Interlinked Data Sets
