Here is Andy Smith's presentation from The National Learning Platforms Conference 2011.
Andy spoke in the Transform session titled 'Extending the possibilities of your platform with the Frog Developer Platform'
11. FDP Widgets Built using standard web technologies: HTML CSS JavaScript
12. FDP Widget Libraries Interact with your Frog data Access external data sources via APIs Easy manipulation of the HTML DOM
13. Frog API Standard, controlled, secure way of interacting with your Frog data. Create, Read, Update, Delete. Available within Frog via FDP Widgets. Available outside Frog via HTTP.
20. Security Wait – ALL my Frog data is external? All API calls are authenticated. Same per-user authentication as the platform. Per-school control over which APIs are available, and which are allowed on a per-widget basis. External authentication is based on oAuth tokens, which you can revoke.
