I had one editorial/stylistic comment from January that I feel is pertinent at this stage; it concerns section 4. L: introduction I think this could be improved with additional text along the lines of: [[ OWL DL has semantics defined over the abstract syntax and a concrete syntax consisting of a subset of RDF graphs. Hence it is necessary to relate specific abstract syntax ontologies with specific RDF/XML documents and their corresponding graphs. This section defines a many-to-many relationship between abstract syntax ontologies and RDF graphs. This is done using a set of nondeterministic mapping rules. Thus to apply the semantics to a particular RDF graph it is necessary to find one of the abstract syntax ontologies that correspond with that graph under the mapping rules and to apply the semantics to that abstract ontology. The mapping is designed so that any of the RDF/XML graphs that correspond to a particular abstarct ontology have the same meaning, as do any of the abstract ontologies that correspond to a particular RDF/XML graph. Moreover, since this process cannot be applied to RDF graphs that do not have corresponding abstract syntax forms, the mapping rules implicitly define a set of graphs, which syntactically characterise OWL DL in RDF/XML. Since running the mapping rules backwards is difficult an alternative syntactic characterization of OWL DL in RDF graphs is also given. ]] That's it - I have now completed a rapid re-review of S&AS.
