Re: Ontology Imports

Good catch! As Adam pointed out, you're using the read() method with a wrong second argument, i.e. when you use model.read(String url, String base) the second argument is the base IRI. What you probably want is to use the read() method with three arguments having the signature

I cannot find a method read(InputStream stream, String Lang) on Model (from which OntModel inherits its "read" methods). Are you by chance using read(InputStream in, String base), which is a very different semantic? --- A. Soroka The University of Virginia Library > On Mar 31, 2017, at 2:38

Sorry for the confusion, yes it is in the UI that I want to add the prefixes. we = my development team + customer. Customer adds data to a graph, enhancing data produced by the application. They can specify any namespace they wish for the enhancing data. I want to collect those namespaces (for
