Hi clerezza people,

I ran into an issue with SchemaGen. I tried to create a Java class
representing the Calais Ontology (
http://www.opencalais.com/files/OpenCalaisLinkedDataSchema_R4_Jan09.rdfs_.txt).
The problem is, that the Ontology uses paths instead of fragment identifiers
to identify and classify different "types", "entities", etc.

e.g.:
http://s.opencalais.com/1/type/em/e/Anniversary
http://s.opencalais.com/1/type/er/Company
http://s.opencalais.com/1/type/er/Geo/City

Now SchemaGen needs me to declare the Ontology like this:
<owl:Ontology rdf:about="http://s.opencalais.com/1/"; />

But this won't work, because SchemaGen fails to generate java constants from
paths, e.g. it won't be able to create a constant from
type/em/e/Anniversary.
Therefore I need to declare the ontology for each different subpath like
this:
<owl:Ontology rdf:about="http://s.opencalais.com/1/type/em/e/"; />
<owl:Ontology rdf:about="http://s.opencalais.com/1/type/er/"; />
<owl:Ontology rdf:about="http://s.opencalais.com/1/type/er/Geo/"; />

And I need to do this in 3 different files.

This is pretty annoying. Is there any way to circumvent this?

If not, what would be a clever way to avoid this problem? I assume the
problem stems from SchemaGen trying to create Java Constants with slashes in
their names which I assume is illegal. We could do a simple solution of
using some other character in this case (e.g. "_"). But does anyone have an
idea how to solve this issue in a nicer way?

Daniel
