I don't consider either to be reasonable -- especially since the current modified TDL/S-P/++ proposal on the table makes either choice unnecessary. > I think the S-A idiom may well prove more attractive to the document writer > than the D idiom. (It is less characters to type). We have to look at the sum total of usability. I still think the D idiom is "lighter", all things considered. There is also the loss of the elegant symmetry between the global and local variants differing only by the presence or absence of the rdf:dtype arc(s) and one could easily make all implicit typing explicit by simply adding those arcs, if one wanted to e.g. export some knowledge to an environment which either did not support global schema knowledge. Such relationships between the S-A idiom and the TDL/S-P/++ idioms are far far more complex. Why burden the users. Common perception is that RDF is already hard to understand. Please let's keep it simple. But, I've stated my position, so I won't belabor the point further. -- Patrick Stickler Phone: +358 50 483 9453 Senior Research Scientist Fax: +358 7180 35409 Nokia Research Center Email: patrick.stickler@nokia.com
