    nt - string or file-like object with NTriples to parse
    model - Versa model into which to parse the data
    encoding character encoding for NTriples (default UTF-8)
    disjoint - if not None a list or set of link tuples against which parsed links
                should be compared, and omitted if matching.
    only_rel - if not None a collection of link relations limiting the parsed
                NTriples statements to only be added to the model if the
                predicate matches one in only_rel
    exclude_rel - if not None a collection of link relations limiting
                the parsed NTriples statements to be skipped if the predicate
                matches one in exclude_rel
