I confirm your statement that the SUO to make a break-through advancement
really needs such a fundamental entity type system as a unifying knowledge
structure. I consider being honoured to cooperate with the SUO WG, to
advance the progress of your grandiouse undertaking, both from scientific
and technological viewpoints .

It seems we succeeded in rendering Aristotle's Logic, Ontology and Physics
formally, in the language of mathematics and computer science, embedding an
ontological theory of relations into his grand knowledge and reasoning
system. Due to such approach, such a universal formal ontology (UFO) can be
useful to putting together as essential components of a whole system both
the upper content ontologies (WordNet, SUMO, CYC, DOLCE, EDR,
EuroWordNetWord) and the formal ontology languages (OWL and OWL Rule).With
this connection it should be mentioned that the OWL Web Ontology Language
pretending to take the first ontological prize mostly because it is actually
rooted in Topics, Book 1 of 11 pages, where, as you know, it was first
developed the formal language of definitions, classes, properties
and semantic rules of reasoning about them, that are embodied in Web data,
documents and applications. Although, there are bad faults, which the
language starts feeling in OWL-S, it is missing the upper ontology
predicates within which the class and property and definition always must
be.
