Someone may be able to locate the OSI discussion about the NOKOS (perhaps the issue was discussed and my interpretation is incorrect): http://www.crynwr.com/cgi-bin/ezmlm-cgi?3 This is the actual licence for the software Kevin described: http://wilbur-rdf.sourceforge.net/docs/LICENSE-NOKOS.html I've mentioned this because Original Software is specified as "WILBUR: Nokia RDF Toolkit for CLOS."
