Google Launches OpenSocial to Spread Social Applications Across the Web. OpenSocial — a set of common APIs for building social applications across the web — for developers of social applications and websites that want to add social features.

OpenSocial will unleash more powerful and pervasive social capabilities for the web, empowering developers to build far-reaching applications that users can enjoy regardless of the websites, web applications, or social networks they use. The release of OpenSocial marks the first time that multiple social networks have been made accessible under a common API to make development and distribution easier and more efficient for developers.

The proliferation of unique APIs across dozens of social websites is forcing developers to choose which ones to write applications for – and then spend their time writing separately for each. OpenSocial gives developers of social applications a single set of APIs to learn for their application to run on any OpenSocial-enabled website. By providing these simple, standards-based technologies, OpenSocial will speed innovation and bring more social features to more places across the web. Users win too: they get more interesting, engaging, or useful features faster.

Three APIs available now

The OpenSocial APIs give developers access to the data needed to build social applications: access to a user’s profile, their friends, and the ability to let their friends know that activities have taken place. OpenSocial resources for developers and websites are available now at code.google.com/apis/opensocial.

Developers will have access to:
- Three JavaScript and Gdata APIs to access social functions
- A live developer sandbox on Orkut at sandbox.orkut.com

Websites will have access to:
- A tool to help OpenSocial-enable their websites
- A support forum for communicating with Google and other websites
