Transcript

  • 1. Using RDF Linked Data To Solve Real Problems © 2008 OpenLink Software, All rights reserved.
  • 2. Situation Analysis Agility is the timeless pursuit of enterprises and individuals alike. In all cases, access, integration, and dissemination of data is pivotal. © 2008 OpenLink Software, All rights reserved.
  • 3. What is Linked Data?  A term coined by Tim Berners-Lee that describes HTTP-based Data Access by Reference for the Web  An unobtrusive tweak to the Web that accentuates its core architecture  Use of HTTP based Identifiers for Naming “Things”  Implicit association of Identifiers with their metadata. © 2006 OpenLink Software, All rights reserved.
  • 4. © 2008 OpenLink Software, All rights reserved.
  • 5. Problems  Identity  - People  - Places  - Ideas  - Other Things  Data Access & Integration © 2008 OpenLink Software, All rights reserved.
  • 6. Problem - Identity  Who Am I?  What are my credentials?  Why do I repeat the above each time, across:  Each Web App.  Each Enterprise App. © 2008 OpenLink Software, All rights reserved.
  • 7. Solution – Identity Problem Get Yourself a Data Space that delivers:  A personal HTTP based ID (a URI)  Bind Your ID to an X.509 Certificate  Bind Certificate to your HTTP User Agents (e.g., Browser)  Bind Certificate to your Profile (e.g., a FOAF space). © 2008 OpenLink Software, All rights reserved.
  • 8. Solution – Identity Problem Contd. With your HTTP ID in place you can then achieve the following:  Visit places on HTTP networks with no login and credentials repetitions (Intranet or Web)  Use ACL based policies to confine data access to specific groups of people. © 2008 OpenLink Software, All rights reserved.
  • 9. Simple FOAF+SSL Demo © 2006 OpenLink Software, All rights reserved.
  • 10. © 2008 OpenLink Software, All rights reserved.
  • 11. Collective Intelligence © 2008 OpenLink Software, All rights reserved.
  • 12. Linked Data – Data Aggregation © 2008 OpenLink Software, All rights reserved
  • 13. Problem: Data Access & Integration  Enterprise Silos generated by applications bound to:  Disparate DBMS Engines & Data Models  Disparate Development Frameworks  Data Silos on the Web such as:  Social Networking Services  Discussion Forums  Blogs  Wikis etc. © 2008 OpenLink Software, All rights reserved.
  • 14. Solution – Data Access & Integration  Use Middleware to generate Conceptual Views over Heterogeneous Data Sources  RDBMS to RDF mapping technology e.g., RDF Views over RDBMS data sources  RDFizers to convert unstructured and semi-structured data to RDF. © 2008 OpenLink Software, All rights reserved.
  • 15. Conceptual Views of Disparate Data © 2008 OpenLink Software, All rights reserved
  • 16. RDBMS to Linked Data – Demo 1 © 2006 OpenLink Software, All rights reserved.
  • 17. RDBMS to Linked Data – Demo 2 © 2006 OpenLink Software, All rights reserved.
  • 18. Self Filtering Find (Search++) © 2006 OpenLink Software, All rights reserved.
