I think I've figured out how to use and structure a data source for a table,

as a model for a data source in a table, but what are good ways of modeling
a data source for an outline?
Any type of tree-like data structure is a good candidate. Trees are
a basic data structures topic, not specific to Cocoa, so you might
want to read up on the subject. The computer section at the
bookstore often includes titles like "Data Structures in
<some_language>," where <some_language> is usually C, C++, or Java,
so if you know any of those languages, such a book might not be a
waste of money (or you can always browse the sections you care about
for free in the bookstore...). I believe pointers to code for
Objective-C data structures have also been posted to this list.
I don't see many discussions of outlines, are
there any good docs/examples around?
There are the Apple examples in /Developer/Examples/AppKit. The two
that use NSOutlineView are DragNDropOutlineView and OutlineView.
It shouldn't be hard to find examples on the Web. The usual suspects include:

Of course, another good source of info is to search the archives for
this mailing list.
