I should have written an article/tutorial on how to implement/use Shindig to convert your SNS into and OpenSocial compliant SNS. Time, however, has prevented me from doing it so far. May be sometime later.
For now, you can have a look at my presentation on the same topic. I had presented it at Barcamp Bangalore 7, and PHPCamp Pune. It was recommended by Dan Peterson, Google, on the Shindig developer’s mailing list.
For those who don’t have an idea what I am talking about; I have been (officially) working on OpenSocial for quite sometime. OpenSocial is a specification developed by giants like Google, MySpace, Ning, etc. to provide a common platform (API) for social app developers. Shindig, an Apache incubator project, is what can help your site become OpenSocial compliant.
By the way, I am referring to the Six degrees of Separation in the initial slides.
