OpenSocial 0.9 - Future Directions
Goal:
– Enable a faster development experience that is both secure and
efficient
Solution: “Opensocial Templates”!
OS Templates core principles:
• Client-side and server-side processing
• Standard set of tags with extensibility model
– Example: <os:ShowPerson>
• http://groups.google.com/group/opensocial-and-gadgets-
spec/web/opensocial-templates
– Demo: http://ostemplates-demo.appspot.com/

How do you host OpenSocial Applications?
1. Can build your own server that implements
OpenSocial specification…
2. Or can use “Shindig” - Reference implementation for
OpenSocial
21

Hosting OpenSocial Applications
What is Shindig?
• Apache Incubator Project
• Currently available in Java and PHP
• Shindig Components:
• Gadget Server
•Parses gadget XML, renders as HTML/JS/CSS
• OpenSocial Data Server
• Plugs into social graph data
• RESTful, RPC protocol services
• Downloaded JavaScript libraries
•Core gadgets, OpenSocial client JavaScript environment

• Strong Open Source community
• High quality production-ready code
• Used by: hi5, orkut, iGoogle, Netlog, Hyves …
• Synchronized with specification
• Language neutral (Java, PHP, …)
