Just some short comments to some key OWL2 claims:
1. Partiality. The data type model, the logical basis of OWL 2, seemingly 
pasted from Motik's paper, is too partial and too formal and too logical, no 
real semantic functions and corresponding rules, See Reality, Universal 
Ontology...;
2. Misplacement of categories, the logical entities for the ontological 
entities. See Ontopaedia."OWL 2 allows for annotations of ontologies, 
ontology entities (classes, properties, and individuals), anonymous 
individuals, axioms, and other annotations. Annotations of all these types, 
however, have no semantic meaning in OWL 2 and are ignored in this document 
(Direct Semantics). http://www.w3.org/TR/2008/WD-owl2-semantics-20081008/
3. Inconsistency. "OWL 2 ontologies consist of the following three different 
syntactic categories: entities (classes, properties, individuals), class 
expressions, axioms. http://www.w3.org/TR/2008/WD-owl2-syntax-20081008/

I haven't read all the sequel but have an impression that OWL 0 was tended 
to be more consistent and comprehensive and less formal logical. It is good 
to remember that the SW is a web of data about the world, and that the SW's 
ontological language is designed to describe how the data relates to the 
real world entities, http://www.w3.org/2001/sw/.

With sincere intentions to better your project,
