I use the workaround Ian mentionned.
It works fine for OntTools.namedHierarchyRoots().
But another question arises now:
I want to list properties whose domain includes Album106591815.
Here is roughly how I want to do that:
OntClass album106591815 =
theTopMostModelWithTheOwlMemSpec.getOntClass("http://dbpedia.org/class/yago/Album106591815";);
List result = album106591815.listDeclaredProperties(false).toList();
This code returns an empty result.
Is it the expected behaviour?
When calling album106591815.listAllProperties(), through my debugger,
the returned list does contain
the property "http://dbpedia.org/property/after";.
But when calling album106591815.listDeclaredProperties(false), then
the property "http://dbpedia.org/property/after"; is absent.
Is it a feature?
In that case, what is the best way to list properties whose domain
includes Album106591815 ?
Thanks for your help.
