The method recursively loads ontologies starting form ontology depicted by myURL

Parameters:

myURL - The url of the ontology to be loaded

maxLoadingDepth - Indicates to which level the timported ontologies should be laoded maxLoadingDepth less then 0 (for instance -1) will cause loading of all ontologies regardless of inclusion depth

Returns:

Returns a set of namespaces loaded during this step

Throws:

jtp.InconsistencyException - when loading of the ontology failed.
