model validation issue

Hi,
I´m experiencing an issue with model validation. I attached a snippet of my
ontology which contains the necessary parts. Whenever I use the following
code which is a simplified version of the real coding, I´m getting the
validation error from below.

InfModel inferredModel =
ModelFactory.createInfModel(ReasonerRegistry.getOWLReasoner(),
ModelFactory.createDefaultModel());
URL weather = this.getClass().getResource("weatherontology.owl");
inferredModel.read(weather.toString());
ValidityReport report = inferredModel.validate();
Iterator<Report> it = report.getReports();
while(it.hasNext()) {
Report rep = it.next();
System.out.println(rep.toString());

Assert.assertTrue(report.isValid());

However, if I change the very first line to the following, it is working
fine:

InfModel inferredModel = ModelFactory.createOntologyModel();

Validation error:

Error ("range check"): "Incorrectly typed literal due to range (prop,
value)"

Any clue on this?
