Well, no.  It's a graph connecting each file to its metadata.  In the
directory view, it's a map.  From the file side, not quite, but there
is a necessary structure there.  That's why I referred to it as a
"directory".

Of course it does, at a minimum there's a readonly attribute, and you
could argue that the extension determines executability.  What it
doesn't have at all is ownership information.

Well, for my purpose I want this stuff structured on a per-file basis,
whether the data is kept in a glob (the directory itself), in the file
itself (conceptually, the Macintosh resource fork), or in a separate
object (inode).  Again, contents and non-content information could
easily be taken as unstructured in that way.

There may be no good way to provide those connotations, but that's
what I'm after.
