There are two open issues with syntax of user defined datatypes in the current documents. The first, ISSUE-29 , regarding the in-line syntax for user defined datatypes, questions the namespace used for the DataRange construct and facets in the RDF/XML mapping. It notes the decision to reuse semantics of RDF & XSD without reusing the namespaces - an issue that needs to be discussed before resolution. It may be easier to leverage existing toolsets, both for reasoning and ontology editing, if XSD syntax is re-used, but I am uncertain. The second, ISSUE-31 , is an issue first identified with OWL 1.0 with respect to referencing externally defined datatypes, summarized well by Jeremy and Jeff Pan at [1]. In the interest of moving forward, I request both of these issues be added to the next telecon agenda. Presumably both of the resolution to each of these issues should be run past the XML Schema WG for feedback. Unless there is someone here with direct ties to that WG, I'm happy to act as a liason. I've started a new wiki page at [2] to aggregate discussion of unary datatype issues, starting with the two above. At [3] I've started a wiki page for reports on reasoner support and aim to populate it in the coming days.
