Thanks for your comments on the RDF semantics document. I will adopt your editorial suggestions, correct typos, and will try to remove uses of terminology with any potential philosophical penumbra from the technical prose in the document. I have one clarification question concerning your comment on datatypes: 3.2. Types as lexical mappings (schema-related) A datatype is an entity characterized by a set of character strings called lexical forms and a mapping from that set to a set of values. We have a couple of reservations concerning this characterization. ... * The statement describes (with the exception of the problem just noted) simple datatypes, but not the class of complex datatypes which can be defined by XML Schema, nor all the types (or type-like constructs) definable in various other schema languages for XML. I have followed other authors in this characterization, and am somewhat surprised to discover that it is incomplete or inadequate. Can you suggest, or point me to a source for, a definition which does cover the more general case, or which clarifies what is wrong with this characterization? We are supposed to have a datatyping framework which can handle all the built-in XML Schema datatypes. Thanks for any help you can give.
