n-ary datatypes

WITDRAWN: Doubts about n-ary datatypes

State:
CLOSED
Product:
Raised by:
Bijan Parsia
Opened on:
2007-10-24
Description:
From: http://code.google.com/p/owl1-1/issues/detail?id=12

Reported by bparsia, Mar 29, 2007

See:
   http://lists.w3.org/Archives/Public/public-owl-dev/2007JanMar/0162.html

Brief summary (even if you dump datatype groups, which were not intended to be part of OWL 1.1; this should be clarified): N-ary datatypes seem both fragile and wrongly expressive (as compared, e.g., to dl-safe rules with built-ins). The key example is unit conversions.

Comment 1 by bparsia, Mar 29, 2007

Also, there are no built-in n-ary datatypes, nor a language for defining them. E.g., see:
