This will be clearer with an example. Assume that the parts have URIs.
Consider a simple statement S1: Water-Is-Transparent
Consider another statement S2: He-Believes-(Water-Is-Transparent)
How can one write statement S2 as He-Believes-S1 using RDF? Is there a way in the any knowledge representation (RDF or another) or logic framework that allows making statements such as S2 that derive some parts from previous statements?
