Solving Real Problems Using Linked Data

Download as PPT, PDF

rumito

The document discusses using linked data to solve problems of identity and data access/integration. It describes linked data as data that is accessible over HTTP and implicitly associated with metadata. It then outlines problems around identity, such as repeating credentials across different apps/enterprises. The solution proposed is assigning individuals HTTP-based IDs and binding IDs to certificates and profiles. Problems of data silos across different databases and apps are also described, with the solution being to generate conceptual views over heterogeneous sources using middleware and RDF.

Using RDF Linked Data To Solve Real Problems © 2008 OpenLink Software, All rights reserved.
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.
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.
© 2008 OpenLink Software, All rights reserved.
Problems  Identity  - People  - Places  - Ideas  - Other Things  Data Access & Integration © 2008 OpenLink Software, All rights reserved.
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.
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.
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.

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.
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.
