[various stuff snipped]
I've been avidly following this discussion, and also carefully read
the dialog between Jeff and Tim Berners-Lee publicly logged at [1].
I find myself torn - on the one hand, I'm certainly familiar with
Jeff's work in SHOE and the use of something like "imports" to mean
"Commits to" -- i.e. that I agree with EVERYTHING that some ontology
(or set of instances or whatever) says, whether I link to it directly
or not. On the other hand, I'm beginning to better understand what
Dan (and Tim) are saying about maybe we want to allow more freedom to
explore different commitment methods and the like.
I would ask the following - if imports is an optional feature (we've
already agreed it doesn't have to be used), and since anyone can
invent their own term to explore a different commitment strategy what
is the downside of including an imports statement of the type Jeff
advocates?)
For example, I am playing with something that looks a bit like this:
<> jim:commits
[jim:partialMappingTo foo: ;
jim:usingMappingRules bar: ] .
in some recent research, and don't see where the existence of
imports, which I won't use here, bothers me. I couldn't live with
the meaning that referring to something in another ontology
automatically had the strong implication that imports does (total
agreement), but I have no real problem with one I don't have to use,
but can if I want that particular meaning.
So Dan, I guess this is to you -- why do you think including one
particular imports method would be premature standardization? Would
it help if we made sure that documents (all or some) made it very
clear that this use of imports was optional?

p.s. This is not meant to be rhetorical, I'm really trying to
understand both sides.
