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:

Listing . ch18_07.rdf
 
<?xml version="1.0" ?>
<rdf:RDF xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:dc="http://www.purl.org/DC/">

    <rdf:Description about="http://www.starpowder.com/planets.html">
					<dc:Title>Mercury</dc:Title>
					<dc:Creator>
					<rdf:Description about="http://www.starpowder.com/NickC.html">
					<dc:Title>Nicolas Copernicus</dc:Title>
					<dc:Language>en</dc:Language> ...
