Data Portability

What is Data Portability about?

Freeing Data from the Tyranny of
Application Lock-in
(Silo Busting!)

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?

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

Identity & Data Meshing (Silo-Busting)

Use of .Name Domains for minting Individual Entity IDs (URIs)
Platforms that generate Web Data associated with individual identity
- Handle .Name registration
- DNS configuration
- Leverage shared vocabularies an ontologies (FOAF, SIOC, and others)
- Deploy Linked Data

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

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 :-)
