Yes, inconsistency is the worst kind of directionality problem, but to me
Directionality is still a problem in itself. An RDF browser that shows you
both the incoming and outgoing triples is *addressing* that problem, as is
anything that infers the inverses. But the problem still exists. It's an
artificial skew between the logical properties of the data and the manifest
properties in the system. An alternate data-modeling regime in which both
directions are always explicitly asserted would not have this problem (but
would take on, obviously, a higher burden on internal consistency as a
result).

I like your additions of Licensing, Sustainability and Authority.
