Neither of these things >actually are properties of anything, in fact, so how can one be a >subproperty of the other? Ah well, never mind. It may not mean much formally, but I think there are situations where it can be useful. For example, when generating graphical views of RDF documents, Dan Connolly's work [1] uses cwm rules to generate new graph-property assertions from the RDF statements in a graph, and in so doing defines the graphical view to be constructed. If one interprets the link "seeAlso" as meaning that more information about the subject can be found at the object resource, then it seems reasonable that definedBy also satisfies that description. Thus, by defining rules that seeAlso links are represented in one's graphical presentation, the definedBy links get included when evaluating the graph under RDFS closure rules. #g [1] Circles and arrows diagrams using stylesheet rules.
