Reference
From MoodleDocs
This is the start of a few pages of largely version independent reference
In the spirit of wiki and in response to the post here: http://moodle.org/mod/forum/discuss.php?d=205117
Go for it Guillermo.
Maybe start here, and later on add a category:Reference and see what happens. I've set a watch on, and I may do a page on JSON errors.
