Pat, (01)
You answer makes clear how Semantic Web is supposed to operate. However, it
seems to leave very important practical consideration outside of its scope. (02)

I strongly agree. There are implicit assumptions behind any inference which are
not part of any specification. If one wants to apply Semantic Web to a
particular problem, then some of these assumptions must be evaluated with
respect to the problem domain. Or are you suggesting that assumptions implicit
in SW core meta-theory are never in conflict with any problem domain, as long
as the problem defined in terms of the same meta-theory? In that case we are
forced into Closed World Assumption which may not be practical for distributed
knowledge. (04)

But what if one can not draw necessary conclusions to do the job - where do we
go from here? Does SW offer any means for negotiating additional required
knowledge to make further inferences? (06)

I think that is the question of great practical significance. The "level of
misunderstanding" can be replaced with more formal criteria based on specific
conclusions that could not be made. Then some of initial assumptions can be
revised and resulting "damage" assessed to answer the second question. (08)
