Mike,
If a "single, monolithic ontology" won't suffice for all
content developers with their various interests and contexts, then
neither will a registry that organizes one, two or ten ontologies.
This is just the problem with specifing a set of usable concepts for many
purposes, and I think it is largely independent of considerations of
using or not using something called a "registry." Now if
there isn't a magic bullet (and I believe you don't think that there is),
then how best should we move toward an SUO? I assume you reject the
monolith approach, and accept some form of "scalable, modular
framework."
Yes, but I should say again that I think we may be making
too big a deal of the need to be flexible with respect to new reasoning
approaches, see below.
If that framework isn't to have a registry for incorporating and managing
its content, what should it have? If it is to have some notion of a
registry, what's wrong with the current attempts to outline one?
Well, as I said, I don't want the SUO to end up being
nothing more than a registry of largely overlapping ontologies.
Is it that foundationally similar ontologies would have to
co-exist? Is that too redundant? But then what is the
option? One proprietary standard is backed and (by hypothesis it
won't suffice for all content developers) and you have to have some way
of adding content to it anyway, and managing the content.
Yes, this is a worry, It would be nice to adopt a single convention for
labeling events, attributes, collections, specifying role players,
articulating causal interactions, etc.. You would need a way to add
content to the SUMO. But you don't need a way to add redundant
content to it.
In the end I confess that the distinction that eludes me is the one
implicitly presumed (by you? or no?): that there is some stable
coherent ontology that will do just fine and then there is this hodge
podge "registry."
Truth be told, I do think that is more or less possible. This SUO,
in my mind will truly be upper level. I'm not envisioning it being
Cyc 2. If you need to represent fish one way and I need to
represent them another, then the SUO should provide some of the basic
tools for each of these distinct representations but the SUO itself
should not have the concept "fish" in it. So your
need to come up with a different kind of representation from the one that
the University of Guelph uses in their fish ontology, wouldn't obviously
have perturbations that will manifest themselves in changes to the
SUO. However, I also concur that there are fundamental
representational issues that should be decided by application, e.g.,
3D-4D, Davidsonian approach to event representation, etc. and that the
SUO content should reflect and allow for this.
Finally, is your worry that the registry is a "waste of time"
because all of the work goes into matching disparate terms from disparate
sources instead of making new content? Well, then leave it minimal,
people can spend their time how they see fit (like in making content for
their own purposes). But if there is a need to put more work into
it, great. There will be a framework and toolset for doing
this. Or am I missing something? Some deep fundamental
problem with the 'registry'?
Yes, this is also a worry. What do you mean, leave it minimal?

- OK, your note below makes your concerns clear.
