MySpace was the first of the Big Three to announce tools for third party sites to integrate MySpace user data into their services (called, collectively, Data Availability). A day later Facebook announced Facebook Connect, then came Google Friend Connect three days after that.
Today MySpace is fully launching Data Availability (look for it this afternoon at developer.myspace.com), and any third party developer can now build applications using their APIs. Google’s product remains in a test phase with a handful of sites (example), and we won’t likely hear more from Facebook until their F8 conference in late July.
MySpace is taking a much more interesting approach than Google, which controls data sent to third party sites via an iframe. MySpace is actually streaming data to these sites, which allows for true integration between the services, not just a bolted-on social tool.
Developers can access any publicly available profile data from a MySpace user and integrate it into their site. This includes a user’s name, picture, bio, social graph (list of friends), and other information. Users authorize the data transfer via a one-time secure OAuth login to MySpace from the third party service. The service is then allowed to access the data.
Like Google and Facebook, users will be able to revoke access by any third party via a privacy control panel on their MySpace account:
