  • 5. What is OpenSocial?
    • OpenSocial is a set of common APIs for building social applications across the web
    • It is being developed by Google in conjunction with partners from the Web/Social Application development community
  • 6. Why OpenSocial is Important?
    • The Web is better when its social
    • Isn’t the Web social already?
    • 100s of millions of users already have signed up for social networks around the world
    • That’s great, but we believe it can get better
  • 7. The problem of social network development “ .. But what if you want to build an application that will run on multiple social websites?”
    • Problem: Developers have to learn multiple APIs to publish in multiple environments
    • Solution: OpenSocial allows developers to write applications to a common standard API that will run on multiple websites!
    • As each social website opens its environment to developers, it exposes an API
  • 8. OpenSocial solves this problem
  • 9. OpenSocial solves this problem

    • It’s about more , more , more

    For Web developers this equates to distribution , distribution , distribution!
