Issue 10877: Classes of classes (odm-ftf) Source: NIST (Mr. Conrad Bock, conrad.bock(at)nist.gov) Nature: Revision Severity: Critical Summary: Classes of classes. In 16.2.3 (More Advanced Concepts), seventh paragraph, the second sentence implies classes are not instances in OWL DL, but even in DL, OWL Class is a class of classes, by definition. For example, an ontology of animals might have the class Dog, which is an instance (of OWL Class) and a class (of Fido, Rover, and other individual dogs). Ther third sentence should be moved to be the second, and start with "however"|, because it is an exception to the first sentence. After "declaration" should be replaced wtih "a common superclass". Resolution: Revised Text: Actions taken: March 30, 2007: received issue Discussion: FTF resources were scarce and priority was given to issues against normative sections, hence many issues such as this were left unresolved.
