Facebook has Developer Platform for some time now. Obviously, MySpace won’t stay behind and let Facebook take all the credit. To counter Facebook, MySpace has announced the release of its own Developer Platform. That’s not all, MySpace Developer Platform is supporting OpenSocial API, an API that was released by Google awhile ago and has been giggling in the web since then.
As the title says, Google has released a new Social Graph API that reads public data from different social web sites and links the relations between people in the web. Basically, Google crawls between people’s relations and connections which is available in public personal data anywhere in the web, then it will find FOAF and XFN relations or any other way of connections as Google says.
So if I’m your friend, and you’re a friend of person B, and person B adds person C in his blogroll then Google Graph API can tell me that I have a connection with person B and also C whether that connection was found directly or indirectly.
