OpenSocial
OpenSocial is a public specification that defines a component hosting environment (container) and a set of common application programming interfaces (APIs) for web applications. Initially, it was designed for social network applications. It was developed by Google along with MySpace and several other social networks. Recently, it has been adopted as a general use runtime environment for allowing untrusted and partially trusted components from third parties to run in an existing web application. The OpenSocial Foundation moved to integrate or support numerous other Open Web technologies. This includes OAuth and OAuth 2.0, Activity Streams, and Portable Contacts, among others. It was released on November 1, 2007. Applications implementing the OpenSocial APIs are interoperable with any social network system that supports them. At launch, OpenSocial took a one-size-fits-all approach to development. As it became more robust and the user-base expanded, OpenSocial modularized the platform to allow developers to only include the parts of the platform it needed. On December 16, 2014, the W3C issued a press release, "OpenSocial Foundation Moving Standards Work to W3C Social Web Activity", stating that OpenSocial would no longer exist as a separate entity, and encouraging the OpenSocial community to continue development work through the W3C Social
