Issue 10882: Transitive closure (odm-ftf) Source: NIST (Dr. Conrad Bock, conrad.bock(at)nist.gov) Nature: Revision Severity: Significant Summary: Transitive closure. In 16.2.3 (More Advanced Concepts), under the XML example, the paragraph starting "Note that a consequence of", seems to have lost its context. It doesn't appear related to the paragraphs around it. If it is, this should be clarified. Resolution: Replace and append text as described below. Revised Text: The following is the current contents of the first paragraph: It is not required in OWL that there be a constant C such that X = C. All horses have color, but we may not know what color a particular horse has. The current document then has two more paragraphs (not shown) followed by the following paragraph: Note that a consequence of this possible indeterminacy, it may not be possible to compute a transitive closure for a property across several ontologies, even if they share individuals Replace the above paragraphs with the following: UML and OWL do not require that there is a constant C such that X = C, e.g., all horses have color, but we may not know what color a particular horse has. As consequence of this possible indeterminacy, it may not be possible to compute a transitive closure for a property across several ontologies, even if they share individuals.
