That depends on the semantics of the relations you use to relate the biological entity with believe, evidence and provenance. Change "this statement is believed by..." to "the existence of this entity is believed by...", change "this statement was derived from document..." to "the existence of this entity is also described by document..." and so on.

This is not a hack at all when you use the properties I described above. It is fully inside standard RDF and OWL semantics and can be expressed in RDF/XML without any problems. Introducing thousands of tiny RDF files just to be able to refer to the statements separately -- THAT is a hack and will break when things get more complicated. The approach I described above should scale without problems.
