BMM12 — Category of Category

Categorization (of Assessment, Influencer and Influencing Organization) would be much more flexible, with very limited impact on the metamodel, if the BMM supported categories of categories.
Suggested by Ed Barkmeyer (NIST) and supported by John Hall (Inferware, Model Systems) and Andy Evans (Xactium)

Resolution:
Add the following associations
Association Location Page
Broader Organization Category categorizes Narrower Organization Category figure 7.3figure 8.129.19.5 18446673
Also add text "Organization categories may themselves be categorized in broader categories; a narrower category may be included in more than one broader category" 8.4.3, following 3rd paragraph after figure 8.12
Broader Influencer Category categorizes Narrower Influencer Category figure 7.3figure 8.129.19.5 18446573
Also add text "Influencer Categories may themselves be categorized in broader categories; a narrower category may be included in more than one broader category" 8.4.2 following first sentence 39
Broader Assessment Category categorizes Narrower Assessment Category figure 7.3figure 8.179.19.5 18476072
Also add text "Categories of assessment may themselves be categorized in broader categories; a narrower category may be included in more than one broader category" 8.4.6.2 following figure 8.17 47
Discussion:
No attempt has been made to optimize or generalize the 'category of category' pattern, since the semantics of the three occurrences are local, e.g. an Assessment Category can categorize other Assessment Categories, but not Influencer Categories or Organization Categories.
Revised Text:

Add the following associations to the BMM:
Broader Organization Category categorizes Narrower Organization Category
Broader Influencer Category categorizes Narrower Influencer Category
Broader Assessment Category categorizes Narrower Assessment Category
