Issue 9018: Section: 10.3 (mof2core-rtf)
Source:  (, )
Nature: Clarification
Severity: Critical
Summary: As per MOF specification only one property can be id. isID defines Id property for Class. Query is... 1) IF I have a Class say "Class1" which has property say "prop1" which is defined as Id. And there is "Class2" which inherits from "Class1" Then 1)Does "Class2" also inherit Id of "Class1"? 2)Can "Class2" has its owned id property? like overiding id property etc? Basically in specification there is no mention of relationship between inheritance of Classes and there id properties. 2) Also we see a single id property is too restrictive. In fact for the UML Meta model's Classes we could not define any single property as a identifying property. Is there any plan to make multiple properties as identifier in MOF?
