Some links documents that describe the ontology in question:

1. 
http://linkeddata.uriburner.com/about/html/http/www.imagesnippets.com/lio/lio.owl 

2. 
http://linkeddata.uriburner.com/describe/?uri=http%3A%2F%2Fwww.imagesnippets.com%2Flio%2Flio.owl

Margaret:

You could enhance the ontology further (esp. for Linked Data 
followy-your-nose style exploration) by adding rdfs:isDefinedBy 
relations that associate the ontology with the classes and properties 
that it defines.
