I have a requirement where I have created an application ontology. Individuals

OntModel backed by TDB.

My questions -
1) As the data keeps on growing, will the entire ontology (classes + instances) be 
loaded each time I call TDBFactory.createNamedModel(ONT_URI,<directory>));

No. The data stays on disk, TDB loads information it needs to scan those parts of the indexes needed for any query but it does not load the whole model.

2) Is there any way to load just the schema (classes + property) definitions 
and avoid loading any instances ? I can create separate uris for classes and 
instances but that the instance ontology will soon be out of proportion.
