RDF in chemistry

What is it about?

This papers outlines some basics of the technologies underlying the semantic web. It shows how the basic bit of knowledge is encoded into a so-called triple that consists of three parts: something about which something is said, what is being said about that thing, and what the meaning of that is. For example, these three things could be "methane" "is a" "gas".
