Data Portability


Data portability is about you, the user, being able to move and use your data across space and across time.


  • your data - whether you created it or purchased it
  • across space - different websites, different devices, different media, different applications, space-shifting in general
  • across time - archiving at one point in time, retrieving at another point in time, time-shifting in general

Relation to microformats

Data portability was, and remains, one of the incentives behind the development of microformats, and now microformats have provided key building blocks for enabling or improving data portability across a variety contexts:

  • contact information portability. hCard has lowered the barrier to sharing contact information on the Web compatibly with the industry standard vCard (RFC 2426) format.
  • event portability. With hCalendar, it is possible to upload an event from one calendar site to another and the portability of iCalendar (RFC 2445) data has also been enhanced for the Web.
  • social-network-portability
  • ...
