Re: [ol-discuss] OpenLibrary API RDF wrapper on Google App Engine

Thomas,

This is very interesting. I've spent some time looking at the OL data  
and transforming it into RDF also.

Have you spent any time trying to provide more links within the data,  
rather than out to other data sets?

Also, in the example you gave, http://olrdf.appspot.com/key/b/OL5218098M.rdf 
  you have a contributor that looks a little odd:

	<rdf:Description rdf:about="Weisgard, Leonard, 1916- illus."/>

Is this because OL doesn't provide URIs for the illustrators? If so,  
perhaps it should be a blank node:

	<bibo:contributorList rdf:parseType="Collection">
		<foaf:Person>
			<foaf:name>Weisgard, Leonard, 1916- illus.</foaf:name>
		</foaf:Person>
	</bibo:contributorList>

This is a great start. Is OL planning to integrate your work into the  
OL interface?
