Programming Social Applications

Use REST Endpoints, Not FQL

While the Facebook Query Language (FQL) might be easy to work with (since it has an SQL-like syntax and provides easy access to users’ social data), if you use FQL in your application, you’re in for a major overhaul when porting it from Facebook to an OpenSocial container.

This reiterates the point covered earlier in the section. All social reference feeds should be pulled from a container’s REST endpoints, and all container-specific paths should be mapped into a series of configuration variables so that they can be easily updated for a new container when the application is ported.
