I only agree with this up to a point. It depends on what you're using the "presentation format" for. To the extent that the presentation format is being used for *input*, I agree that the URIs should be omitted (since you're not inputting them). That's the way I'm viewing most of the XML examples in the M&S. If someone were to build a graphical input tool for RDF, where you could input the graphs directly, I'd also see omitting the URIs in those instances as well. However, where you were using the presentation format to display output (what actually got produced), it seems to me you'd display generated URIs as well (as SirPac does). I view the graphs in the M&S as being primarily visual aids, and as such I think it would be clearer to explicitly show generated URIs, as helping to convey the idea that that is what will happen. > > However, I'll also note that this is a side issue.

Well, *some* identifier is needed in the N-triple representation, possibly generated URIs (this is one of the choices). --Frank -- Frank Manola The MITRE Corporation 202 Burlington Road, MS A345 Bedford, MA 01730-1420 mailto:fmanola@mitre.org voice: 781-271-8147 FAX: 781-271-875
