  3. 3. Problem Origins <ul><li>Over emphasis on Applications at the expense of their underlying: </li></ul><ul><li>Database Engines and Data Models (Relational, Hierarchical, Graph) </li></ul><ul><li>Data Access Mechanisms (HTTP based Linked Data, SQL CLIs, Web Services) </li></ul><ul><li>Data Query Mechanisms (SPARQL, SQL, XQuery/XPath, etc) </li></ul>© 2008 OpenLink Software, All rights reserved.

Problem Vectors <ul><li>Identity </li></ul><ul><ul><li>Real World Object Identity </li></ul></ul><ul><li>The Web </li></ul><ul><ul><li>Exponential Growth of Identity Challenged Applications (SaaS) </li></ul></ul><ul><ul><li>Socially induced User Generated Content without Explicit Identity </li></ul></ul><ul><li>The Cloud </li></ul><ul><ul><li>Infrastructure that reduces cost of producing Identity Challenged Applications. </li></ul></ul>© 2008 OpenLink Software, All rights reserved.
  5. 5. Aspects of Data Portability <ul><li>Data Mobility (Import/Export) via standard data formats </li></ul><ul><ul><li>RSS, Atom, OPML </li></ul></ul><ul><ul><li>Microformats (XFN, hCard, hCalendar, Microdata) </li></ul></ul><ul><ul><li>RDF Model Data Representation Formats </li></ul></ul><ul><ul><ul><li>RDFa </li></ul></ul></ul><ul><ul><ul><li>JSON </li></ul></ul></ul><ul><ul><ul><li>N3 / Turtle </li></ul></ul></ul><ul><ul><ul><li>XML - RDF/XML, TriX, TriG, and others. </li></ul></ul></ul>© 2008 OpenLink Software, All rights reserved.

  8. 8. How We Bust Data Silos <ul><li>Use platforms that engender Federated Identity via: </li></ul><ul><li>Personal HTTP Identifiers (WebIDs or Personal URIs) </li></ul><ul><li>WebIDs bound to X.509 Certificates </li></ul><ul><li>Association of WebIDs with accounts in existing Data Silos (Web 2.0 Apps & Services) </li></ul><ul><li>Exposure of Linked Data Spaces built on shared schemas / ontologies. </li></ul>© 2008 OpenLink Software, All rights reserved.
  9. 9. How Web-Scale Data Access Should Work <ul><li>You Get Yourself a WebID via an Identity Service Provider: </li></ul><ul><ul><li>self hosted </li></ul></ul><ul><ul><li>3 rd party hosted </li></ul></ul><ul><ul><li>Profile as a Service (PaaS) solution </li></ul></ul><ul><li>Associate Your WebID with existing Silo-Accounts: </li></ul><ul><ul><li>Blogs, Wikis, Social-Networks, Bookmarks, Photo Galleries, Discussions etc. </li></ul></ul><ul><li>Associate Your WebID with existing OpenID and OAuth services. </li></ul>© 2008 OpenLink Software, All rights reserved.
