What is Data Portability about? :© 2008 OpenLink Software, All rights reserved. What is Data Portability about? Freeing Data from the Tyranny of Application Lock-in (Silo Busting!)


Aspects of Data Portability :© 2008 OpenLink Software, All rights reserved. Aspects of Data Portability Data Mobility (Import/Export) via standard data formats RSS, Atom, OPML Microformats (XFN, hCard, hCalendar, RDFa) RDF (RSS, FOAF, SIOC etc.) Data Access by Reference (Linked Data / WODBC) RDFizers / Drivers Declarative Mappers (e.g. RDBMS to RDF)


Why is Data Portability Important? :© 2008 OpenLink Software, All rights reserved. Why is Data Portability Important? Your Data belongs to You! Information Overload is here! User Generated Content is growing exponentially Web Application Silos are on the rise (e.g Social-Networks and other Software as Service solutions) Still only 24 hrs in a day! You are an Individual Web Individuality is no longer a trivial pursuit Rise of Real-time Enterprises & Individuals

Data Portability Platform Example: ODS :© 2008 OpenLink Software, All rights reserved. Data Portability Platform Example: 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 :© 2008 OpenLink Software, All rights reserved. Some ODS Specific Features Upstreaming via Publishing Protocols All Data is exposed via Shared Ontologies (SIOC, SKOS, AtomOWL, FOAF, Annotea Bookmarks, and more..) All Data is SPARQL Accessible In-built support for GRDDL and other mechanisms for generating RDF from non RDF Data Sources A lot more :-)
