I have updated a number of the examples.
The RDF representation creates, or makes statements about several separate entities.
* Now includes a way to document the original occurrence and id labels
Here is the RDF
Area geo:44.86528100,-87.23147800;u=10
Also there seem to be several OWL validators, some which are for OWL 1 others for OWL 2
Updated the ontologies, but they are not 100% yet.
Beware of Protege !!!, You can create things that look correct and validate in Protege but the actual .owl file is not correct.
Respectfully,
