Issue 1243:  OBV/top of type hierarchy should be abstract (boca-rtf)
Source:  (, )
Nature:  Revision
Severity: 
Summary: Summary: BOCA
 The OMG Objects By Value, document orbos/98-01-18,  defines abstract
 interfaces and indicates how they should be applied to a Busieess Object
 Framework.  Page 8-107, Section 8.10.1, includes the text:
 
 "A base type is a type that appears at the top of a hierarchy that
 includes both regular interface and value types.   For example, it could
 be the root type of a business object framework that includes both
 regular interface types and value types..."
 
 This requires that the common supertype of regular interfaces (e.g.,
 BocaIdentifiable) and  pass-by-value (e.g., most subtypes of
 BocaUnidentifiable) must be abstract.
 
 This issue was addressed in the BOCA errata document bom/98-02-17, but
 was inadvertently lost in the transcription to the final errata
 document.

The OMG Objects By Value, document orbos/98-01-18,  defines abstract
interfaces and indicates how they should be applied to a Busieess
Object
Framework.  Page 8-107, Section 8.10.1, includes the text:

"A base type is a type that appears at the top of a hierarchy that
includes both regular interface and value types.   For example, it
could
be the root type of a business object framework that includes both
regular interface types and value types..."

This requires that the common supertype of regular interfaces (e.g.,
BocaIdentifiable) and  pass-by-value (e.g., most subtypes of
BocaUnidentifiable) must be abstract.

This issue was addressed in the BOCA errata document bom/98-02-17, but

RECOMMENDATION:
*	page 46
	*	reference text: " is_abstract" ... "FALSE"
	*	action: change to "is_abstract" ... "TRUE"
*	page 76
	*	reference text, under "identifiable BocaType:"...
		*	"attribute boolean is_abstract=FALSE;"
	*	action: change to 
		*	"attribute boolean is_abstract=TRUE;"
