Here is the first draft,

Now this is an initial suggestion, I don't expect this to be the final word,
we probably need to work on it :-).  but hey it's a start.

Remember that this hierarchy is not representative of search methods, we
could search many more ways than is suggested by the hierarchy, just the
layout (folder/file wise) of the library.  since the names will be in a
database, it would be easy to search anyway we want.  However, the hierarchy
would and should be the "list of categories" in the database for proper
organization of it all. Hence a new entry would need to be "categorized" by
the author or by someone else. so it can be indexed on searches properly.

P.S. I would have attached this but it seems attachments on newsgroups is
"impossible" or highly unrecommended :-).
