In this period we are developing something similar to a social network (where user authenticate themselves and are registered in the platform and communicate with other socialnetworks like Facebook, Twitter, Foursquare etc..).
It's been decided to use the Open Social standard in order to have a standard JSON format of communication between clients and server. These are the current specification in case you are new to it http://opensocial-resources.googlecode.com/svn/spec/1.1/Core-Gadget.xml
Did someone ever used this standard before? Is it a good solution? What could be the advantages of using this standard since the most important social network doesn't currently implement it (exception for MySpace and Linkedin)? Any past experience with this?
