1) unimplemented 2) no design for declaring n-ary datatypes To start with the second point: In the syntax doc http://www.w3.org/2007/OWL/wiki/Syntax#Data_Ranges data ranges with arity > 1 are introduced The only constructs used to produce such datatypes are a URI, or DataComplementOf. It refers to the Semantics doc for defns of URIs, but only 1-ary datatypes are listed there in. Essentially, the idea that there is a design for n-ary datatypes is a bluff. A design would include: - means for declaring such datatypes - some predefined datatypes - means for deciding on sensible selections of datatypes that work well together. As far as I am aware, there are implementations that support many of the features of the member submission - however, n-ary datatypes are not supported by any od them. This increases my belief that n-ary datatypes still requires active research work to take what is, I believe, a theoretical design, to turn it into working code. I do not believe that this WG is the appropriate place for such research. Jeremy
