Issue 17477: Inconsistency between Examples (instance models) and meta-model (smm-rtf) Source: Cordys (Mr. Henk de Man, hdman(at)cordys.com) Nature: Revision Severity: Significant Summary: Examples (instance models) in SMM spec suggest that rescaled measure has "operation", but the meta-model has "formula".

Rescaling multiple measurements simultaneously into a single measurement confounds rescale measure with collective measure. Figure 19.19 showing McCabe Cyclomatic Complexity has the operation (that is, formula) as 1+BranchingFactor. It should be 1+baseMeasure.

[hdm] I agree with your suggestion that rescaling is only possible from 1 measurement instead of from multiple measurements simultaneuously. However, during discussions Alain Picard told me that shis was on purpose, but, in all honesty, I did not understand that yet. To me it should be "1" indeed, not "0..*". So I agree with you. Possibly Alain can clarify this further. I thought I had entered this as separate issue, but apparently I forgot this. I will record it separately then.   From: Juergen Boldt [mailto:juergen@omg.org] Sent: Friday, July 13, 2012 11:06 AM To: issues@omg.org; smm-rtf@omg.org Subject: issues 17476 - 17478 -- SMM RTF issues  This is issue # 17476ÂÂÂFrom: Henk de Man AdditiveMeasure In SMM spec the examples (instance models) have "AdditiveMeasure".
