 The basic idea is that truthbearers and facts are both complex structured entities: truthbearers are composed of (other truthbearers and ultimately of) words, or concepts; facts are composed of (other facts or states of affairs and ultimately of) things, properties, and relations. The aim is to show how the correspondence relation is generated from underlying relations between the ultimate constituents of truthbearers, on the one hand, and the ultimate constituents of their corresponding facts, on the other. One part of the project will be concerned with these correspondence-generating relations: it will lead into a theory that addresses the question how simple words, or concepts, can be about things, properties, and relations; i.e., it will merge with semantics or psycho-semantics (depending on what the truthbearers are taken to be). The other part of the project, the specifically ontological part, will have to provide identity criteria for facts and explain how their simple constituents combine into complex wholes.  Putting all this together should yield an account of the conditions determining which truthbearers correspond to which facts.
