I've read it, both at face-value and with an attempt at reading between the lines, and the impression I come away with is that the RDFSchema and XSchema camps have agreed to disagree. This strikes me as tragic. What I'm sure most of us developers want to know is: * How do we decide which one to use (RDFSchema vs. XSchema)? * Are we going to have to live in a world where we have to support both, and have two sets of processors, two sets of specifications, two sets of user guides, converters to/from, etc., etc.? Also, I wonder if anyone can confirm my conjecture that the reason RDFSchema is so underspecified is because of the long shadow cast by the impending XSchema? [It's been at least 6 months since I read RDFSchema, so pardon me if the omissions I list here have been addressed] RDFSchema lacks some obviously useful features, like concrete syntax for specifying whether a value is required or optional, or read-only in a named context, etc. Is it because RDFSchema is waiting until XSchema defines those concepts, and then will incorporate equivalents in a future extension?
