Nesting Resources

What if a property itself needs more description? For example, what if the creator of the resource is described by a Web page and you want to refer the reader to that page? In that case, you can nest <rdf:Resource> elements. For example, if you want to describe Nicolas Copernicus, the creator of planets.html, with another Web page, NickC.html, that might look like this:
