-- example of an entity description missing an rdfs:label relation .    (09)

Basically, whenever you see raw HTTP URIs as opposed to labels for 
description subjects (i.e., what you see after "About: ...." , its 
because our reasoner hasn't found annotation oriented relations which it 
uses to determine entity labels.    (010)

Note, when you see what appear to be duplicates, this is simply the 
consequence of multiple RDF sources contributing to the view/page. To 
filter further, just go to the "Metadata" tab and then select the RDF 
sources (named graphs) to which you want to set the view/page scope.
