Further, it's said a FullBottle results from "pouring"? Is it a different thing if I pour first through a filter into the bottle? Or how about if I collect the liquid into the bottle through a wholly different process, not pouring anything at all --- is that not a "FullBottle" anymore? This is not a rhetorical question - it arises when something is categorically defined with reference to a process or action performed to create it. /jmc PS You are not 'in' a marriage. In fact nothing is "in" a marriage that I know of. Sure a marriage "has" a Wife and "has" a Husband, and you "are" a husband. Why not just use those words? Marriage:Obama has:this Husband:Barack_Obama Marriage:Obama has:this Wife:Michelle_Obama Husband:Barack_Obama is:this Person:Barack_Obama Can this possibly be improved, that is, made more clear to the AVERAGE person? How would other ontologies indicate the same smenatic content -- do they pass the "shared, intuitive understanding" test?

And there's no dispute that the physical organization of a set of triples can be altered without changing the semantics of its statements (but so what?). I do strenuously dispute though that you can "turn adjectives nouns and verbs into each other". And I strenuously argue that any ontology that ignores adjectives and prepositions is seriously, deeply flawed -- such an ontology makes assertions such as yours ("no difference...(between)... a relation/predicate and (its) object") almost reasonable! > > My problem is that there IS a difference. Objects are nouns. Subjects are nouns. But predicates can NOT be nouns; nouns can NOT be predicates. Rather, common nouns connote types of things: they are but labels for distinguishing generic identities.

Well, first off, you see tendencies to define property hierarchies that DUPLICATE noun hierarchites -- same noun, first upper cased in the noun hierarchy and then lower-cased in the property hierarchy -- golly how pregnant with meaning that first letter is made to be! > > How can the outcome of a massively bloated noun-infused property hierarchy be said correct?

We shouldn't over-interpret natural language grammar (nor physical appearance for that matter) when it comes to semantics. I can easily juggle around with adjectives, nouns and verbs and turn them into each other without changing the meaning of the sentence. Natural language grammar is superficial/superimposed structure for a large part. As much as that I can say that I am *IN* a marriage (which I am), I can say that some marriage relates me to my wife. Also, there is no fundamental difference between a relation/predicate on the one hand and an object on the other. They are just different perspectives of the same. A marriage is equally a relation as it is an object. We tend to take them apart, but for superficial reasons (natural language grammar, or mathematics). Reification is no exception, it's the rule. Don't we say that we take *PART* in a relation? >> >> So, I see no problem in having "full bottle" as the relation in this example. It relates "empty bottle" and "liquid". The pouring is the context responsible for defining that relation. In case we can't express contextuality, I would settle for seeing it as the third component of the relation. This makes sense (in this example), because you need "pouring" *FIRST* before you can have full bottles. >> >> By the way, by saying that the difference between *BEING IN SOMETHING* and *TAKING APART IN SOMETHING* is superficial, I do not say that such distinction is always irrelevant. But, in case I would feel that this distinction is relevant, I should think about what makes the difference. This context (the differentiator), though, is *SPECIFIC*, it's not fundamental. This even holds for the physical context. >> >> Cheers! >> >> Paul >> >> FROM: jmcclure@hypergrove.com [mailto:jmcclure@hypergrove.com] >> SENT: maandag 9 september 2013 22:09 >> TO: public-owl-dev@w3.org >> SUBJECT: RE: Question about ontology >> >> Well... If 'part-of' applies to liquid in a fullbottle, then wouldn't it be true you'd say that some car is part-of a full-garage? No, some liquid is IN a bottle, and some car is IN a garage.
