What is a datatype in RDF? Concepts says (in Section 3.3) RDF uses the datatype abstraction defined by XML Schema Part 2: Datatypes ... XML Schema Part 2 says ... a datatype is a 3-tuple, consisting of a) a set of distinct values, called its value space, b) a set of lexical representations, called its lexical space, and c) a set of facets that characterize properties of the value space, individual values or lexical items. (Actually this appears to be a bug in the XML Schema documents, as the lexical-to-value mapping is nowhere indicated.) Let us thus assume that as far as RDF is concerned, this allusion makes a datatype be a value space, a lexical space, a mapping from the latter to the former, and a set of facets. So what happened to the XML Schema datatype facets? Are they part of RDF datatypes?
