I'm doing some research about data portability on the web and I'm a little bit confused by all I read on MySpace Developer Platform. Here is what I understand so far, could you correct me if I'm wrong?

There are 3 different APIs that a developer can use on MySpace:

• The MySpace REST API v1
• The OpenSocial API
• The Data Availability REST API

The first one is still available but will be deprecated. The OpenSocial API (currently 0.7) will replace the v1 API when the 0.8 (currently in developement) is available. The Data Availability is an other MySpace API that is currently usable with the OpenSocial Person ressource only.

Is the Data Availability REST API really supposed to be the 0.8 implementation of the OpenSocial API? What is supposed to be used at the end from an external website to access MySpace data?

 Nobody can help me on this one?

I am struggeling with the same issue.

 v1:  Seems still nicely going (I even have this wonderful interactive test tool on the MySpace site)

v2:  OpenSocial REST API implementation

and the Portable Contacts Rest resources seem to be V2 as well ... indeed, I cannot see event the difference between the "OpenSocial" V2 and the "Portable COntacts" V2.

 Anybody having the overview?

Thanks
