To close the loop on this thread... This was discussed at the 2009-01-28 telecon (minutes at [1]). It is a recognized backwards incompatibility that was considered, during discussion at F2F4, to be acceptable because it made it possible to "include" RDF graphs without ontology headers using owl:imports (as [ISSUE-135] requested), which is believed to be a more common use case. I will review the WebOnt test cases, including those which have already been approved by the WG, to determine which were previously considered syntactically DL and are changed by this constraint. -- Mike Smith Clark & Parsia [1] http://www.w3.org/2007/OWL/meeting/2009-01-28 [ISSUE-135] http://www.w3.org/2007/OWL/tracker/issues/135
