Question about ontology

Hello,

we are group of PHD students and we would like to ask you (ontology
experts) for help/advice.

We`re trying to make a simple expert system using ontology as knowledge
base. We have come to few problems and before making any conclusions, we
would like to confront it with you.

 We noticed that every explanation and example we found uses object
hierarchy, e.g. OneThing isPartOf OtherThing or OneThing hasPart
OtherThings. We don`t know how to model process which also causes that
resulting object will be assembled from some other objects. For example:

   a) Object Empty bottle
   b) Object Liquid
   c) Process: Liquid will be poured into the Empty bottle and thus will
create some new object Bottle filled with liquid - see image attached.


What we need is to define a relation “Pouring” that is between liquid and
empty bottle. In fact we don’t really need “is part of” relations if there
is a way to express “is part of” implicitly in “Pouring” relation, because
it is obvious that the "Bottle with liquid" was created by "Pouring" the
"Liquid" into the "Empty bottle". Also the direction of "Pouring" is
important for us.

So, the question is whether you may help us either by explaining this
particular example or providing us with helpful source of information how
to solve it.

Thanks in advance

Your sincerely
