I guess that can be said about ANY conceivable approach. People that do not care can make mistakes, whatever approach we choose.

I don't think that the large majority of biomedical projects will require us to make such statements. As I said, it is clear that we can think of scenarios where we need RDF reification or something similar -- however, most of these scenarios will not be encountered by the large majority of projects. Time will tell.

I guess we have different standards about what is satisfactory in this context and what is not. In my view, a basic ontology similar to the already existing SWAN ontology [1] would be sufficient for all practical needs. There is no need to come up with an intricate logic of propositional attitudes to implement something like this.

I'm afraid I do not understand what you are referring to.
