Yes. There should be one URI for the service and another URI for the sonnet. The service author could make this more intuitive by using clear names: Service URI: http://www.cpe.fr/cgi-bin/poetry Sonnet URI: http://www.cpe.fr/cgi-bin/poetry?rose I can imagine that there will be tons of confusingly mixed up, badly thought out RDF descriptions of resources. But I do think that applications can be instructed to handle this in many ways. Deduction engines could be built to make intelligent guesses of how a more complete and correct description would look like, based on faulty descriptions. By collecting many versions of the same thing and by using quality ratings and other logic, useful information should be extracted. And I hope that badly expressed descriptions will be substituted with better versions. Anyone can do the rewrite. They will just have to earn the public trust, to go on and be used instead of the original descriptions. This is the future role of the RDF-quality rating services. -- / Jonas - http://paranormal.o.se/perl/proj/rdf/schema_editor/
