In those cases where those individuals are part of the ontology/vocabulary, I
would consider them as part of the terminology and useful to include in the
visualization somehow. Of course you would want to start visualizing all
resources with type foaf:Person :)

I was trying it out with the current draft GS1 Vocabulary:

http://vowl.visualdataweb.org/webvowl/#iri=http://dydra.com/nlv01111/gs1.ttl

Something like GoodRelations also contains predefined/enumerated lists of
values:

http://vowl.visualdataweb.org/webvowl/#iri=http://purl.org/goodrelations/v1



In the GS1 case I notice many of the classes are shown in darker blue as they
are not defined to be an owl:Class, however some of the classes like
http://gs1.org/voc/FasteningTypeCode are shown in lighter blue and shown with
type owl:Class even though this is not stated in the source data. Any ideas why?



Cheers,

John
