Issue 2178:  Define a MOF Class that is the supertype of all Classes (mof-rtf)
Source:  (, )
Nature:  Revision
Severity:  Minor
Summary: Summary: Define a MOF Class that is the supertype of all Classes.
 It could be represented as a single-valued subclass of Model::Class.

July 23, 1999: Deferred
Discussion: 
This would allow us to specify some useful "generic" Packages. For example:
package Extension {
class ExtensionTag {
attribute string tag_name;
attibute any tag_value;
reference to the_element of TagAttachesTo tagged_element;
};
association TagAttachesTo {
ExtensionTag the_tag;
UniversalClass the_element; // need the universal supertype here
};
};
The above approach could be used to make the MOF Model tagging mechanism apply to
all meta-models.
Status: no decisions made. This would allow us to specify some useful "generic" Packages. For example: 

package Extension { 
class ExtensionTag { 
attribute string tag_name; 
attribute any tag_value; 
reference to the_element of TagAttachesTo tagged_element;
}; 
association TagAttachesTo { 
ExtensionTag the_tag; 
UniversalClass the_element; // need it here
};
};
The above approach could be used to make the MOF Model tagging mechanism apply to all meta-models.

Additional Text:

This would allow us to specify some useful "generic" Packages. 
For example:

package Extension {
	class ExtensionTag {
		attribute string tag_name;
		attibute any tag_value;
		reference to the_element of TagAttachesTo
tagged_element;
	};
	association TagAttachesTo {
		ExtensionTag the_tag;
		UniversalClass the_element; 
		// ^^^^^^^^^
		// use the universal supertype here
	};
};

The above example defines a tagging mechanism that can apply to all
meta-models.
