UPDM — Operational views - ActivityRealization

· This extension of association is used to tie an OperationalActivity (an operational view element) to an OperationalActivityRealization (a system view element) or a SystemFunction (a system view element) to an OperationalCapabilityRealization (an operational view element). Based on the semantics description this seems to be intended to create one-to-many mappings between OperationalActivity (s) and SystemFunction(s) in both directions. The above seems a very cumbersome approach and is handled in a far simpler but equally functional way in MODAF/ NAF.
