Sure - I do not argue with that at all.   I was just trying to come up
with the minimal structure.  There can be many more layers of complexity
on top of that.

It seems to me that "ancestors" can be computed for essentially any
hierarchical structure, by "resource-parent" may not have such a
universal meaning.   I know that I can not always organize resource in a
tree.
