RE: SUO: The Story So Far - Request for vote




Dear James,

	I agree with Matthew's answers to your questions; some 
further clarifications follow.

Not necessarily. Since the Scope is formulated in informal terms (an 
ontology is a set of concepts, axioms, and relationships that 
describe a domain of interest), the issue whether this set should be 
limited to mutually consistent axioms is left open. A modular 
structure is compatible with this wording, although a clarification 
would be useful.

I am first seeking a level of consensus. If a good consensus exist, 
then we may decide not to work on monolithic approaches (in practice, 
monolithic approaches may be still pursued by subsets of SUO members, 
who accept at least a formal comparison - if not a "mapping" - 
between their approach and other alternative approaches)

The sense of my proposal is to adopt a different spirit in our 
discussions: instead of defending an certain ontological approach in 
a "religious" way, let's incourage people to explain, motivate and 
formalize their approach (if enough like-minded colleagues are 
willing to help them), in order to perform comparisons and 
evaluations a-posteriori, on the basis of actual usability and formal 
consequences.

Of course, if nobody is willing to work on a particular approach, 
that approach will be automatically dismissed, or "frozen". 
Nevertheless, explicitly considering it as an alternative would have 
a high documentation value, and it would also improve the 
trustability in the SUO methodology.

I believe that the Merged Ontology is a good starting point, which 
must be considered together with other starting points, such as 
Matthew's documents, John's book or our own papers. It has to be 
carefully analyzed, in the light of other independent inputs, in 
order to possibly distinguish different levels of agreement within 
it. Such different agreements will be probably the result of 
different ontological views, which must be isolated, explained, 
motivated and formalized. The result of this process will either be a 
better ontology, or, more probably, a modularized one.

This is an alternative (i.e., "modularizing" the current merged 
ontology, on the basis of other inputs). Another alternative is to 
consider the current merged ontology as a single module, allowing 
comparisons with other modules. I wouldn't support this option.
