Usage of rdfs:isDefinedBy?

What predicate should be used to describe the relationship between
	http://thing-described-by.org?http://dbooth.org/2005/dbooth/
which is a URI for me (David Booth), and
	http://dbooth.org/2005/dbooth/
which is the URI of a Web page that describes me and defines the meaning
of the URI (above) for me?

Would the following triple be an appropriate use of rdfs:isDefinedBy[1]?

	http://thing-described-by.org?http://dbooth.org/2005/dbooth/
		rdfs:isDefinedBy 
			http://dbooth.org/2005/dbooth/ .

If not, how are folks using rdfs:isDefinedBy?
