With apologies for giving you conflicting advice...

I remember, now, that there are all these "how do I do XYZ?" questions among RDF users, and it would be nice for the primer to answer them. (hence my offer to clarify rdf:Alt, which I gather you ended up dealing with without my help.) So while I'd like to minimize the explanation of generalities and background material in the primer, I support explaining how users should go about specific tasks. I think 2 or 3 examples of how to deal with boolean characteristics is in order... one using a class, say GoodThing, but noting we don't have rdf:notType, so this doesn't give you BadThing for free... you might mention owl:complementOf in there... and another example using xsd:boolean. > Now that we > *do* have datatypes, the section looks a bit strange (you can just use > xsd:boolean, a point I recently added to the section).

Do you have examples of dealing with n-ary relations? I saw recent discussion of things versus their names; I'm intersted to have that explained in the primer. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
