Issue 17278: Mapping to DM2 higher level elements: (updm-2-0-rtf)
Source: Syntell AB (Mr Lars-Olof  Kihlstrom, lars-olof.kihlstrom(at)syntell.se)
Nature: Uncategorized Issue
Severity: 
Summary: Currently UPDM does not map a numer of elements that exist in DM2, namely those above the Type level, for example CapabilityType since UML does not support elements at higher type levels. There is however a possibility of doing this by recognising that a set of capabilities (as an example) contains a given capability instance but capability categoreis are really a larger subset of available capabilities. This would make it possible by allowing the elements to contain a tagged value that indicates whether they are to be considered at a higher type level. This would make it possible to provide a mapping between more DM2 elements and UPDM elements than currently possible. It is assumed that a tagged value would be easier to handle than the introduction of additional stereotypes since categories would imply elements with different stereotypes inheriting from one another.

Resolution: 
Revised Text: 
Actions taken:
March 28, 2012: received issue
Discussion: 
Potential need for a capability category tag to capture the powertypes. 
It was felt that this should be rejected for this version of UPDM due to the developments going in with respect to the  unification of the various frameworks

Therefore it was decided to defer this issue. 

Proposed Disposition:	Deferred
