Sorry for the noise, it looks like the listImportedOntologyURIs() was a red
herring -- the submodel count actually comes from InfModel which includes
the schema submodels.
But I was able to dig a little further, and observed after the code I have
shown is executed, there are inconsistencies in models for the same
ontology but accessed in different ways:
ontology.getOntModel().getOntology("
https://localhost:4443/demo/iswc-2017/ns/templates#
").listImports().toList().toString()
[http://atomgraph.com/ns/platform/templates#,
https://www.w3.org/ns/ldt/core/templates#]
ontology.getOntModel().getDocumentManager().getOntology("
https://localhost:4443/demo/iswc-2017/ns/templates#";,
org.apache.jena.ontology.OntModelSpec.OWL_MEM).getOntology("
https://localhost:4443/demo/iswc-2017/ns/templates#
").listImports().toList().toString()
[https://www.w3.org/ns/ldt/core/templates#]
Notice how imports for
https://localhost:4443/demo/iswc-2017/ns/templates# differ.
How is that possible, and how do I avoid this?
