What are all these information in the form based resource editor ?
The current version of the generic resource editor is rather terse. At this point, the resource editor will present all the declared resource attribute values and some ways to edit them. All the attributes are declared in each resource reference manual. Resource editors is an area in which you can expect big improvement in the next release. Right now, it is recommended that you use two browser windows, one displaying the form based editor, and the other one displaying the appropriate reference manual for the resource being edited (which described all the attributes semantics).
