Solving Real Problems Using Linked Data

  1. 1. Using RDF Linked Data To Solve Real Problems © 2008 OpenLink Software, All rights reserved.
  2. 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. 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. 4. © 2008 OpenLink Software, All rights reserved.
  5. 5. Problems  Identity  - People  - Places  - Ideas  - Other Things  Data Access & Integration © 2008 OpenLink Software, All rights reserved.
  6. 6. Problem - Identity  Who Am I ?  What are my credentials ?  Why do I repeat the above, each time I encounter a new:  Each Web Application / Service  Each Enterprise Application / Service. © 2008 OpenLink Software, All rights reserved.
  7. 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. 8. Solution – Identity Problem Contd. With the 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.

  11. 11. Linked Data – Data Aggregation © 2008 OpenLink Software, All rights reserved
  12. 12. 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.
  13. 13. Solution – Data Access & Integration  Use Middleware to generate Conceptual Views over Heterogeneous Data Sources using:  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.
