Yes, a Model is a PrefixMapping, and the usual parsers will load prefixes from the documents they read into the Model. > For example, I create a new model and read in a number of > ontologies (e.g. DBpedia, FOAF) via the Model.read(InputStream, String) > method. If I then call the getNsURIPrefix(String) with a URI (e.g. > http://xmlns.com/foaf/0.1/Person) I would expect that it should return > "foaf" as that prefix was bound when I loaded the FOAF ontology, but > instead it just returns null. The FOAF namespace is http://xmlns.com/foaf/0.1/, not http://xmlns.com/foaf/0.1/Person . The javadoc for getNsURIPrefix(String uri) says Answer the prefix for the given URI, or null if there isn't one It's not as clear as it could be that it means "the name bound as a prefix to this URI", not "the name bound to a prefix of this URI", which I think is what you're expecting.
