Figure 15-4: Behavior Allocation

UPDATE: This spec. diagram is undergoing massive re-working for SysMLv1.7 and is now supported in the MagicDraw SysML Plugin and Magic Model Analyst^® (Cameo Simulation Toolkit^®) with the help of this feature:

SysMLv1.x: MagicDraw/Cameo: Contextual relationships feature (links)

This page has therefore been marked as ARCHIVAL

When following Webel Best Practice please:

DO NOT use Property names that are identical to the names of the Classifier (Class, DataType, Block, ValueType) that type them!

Instead:

SysML: Naming: Always use either anonymous or first letter lower case for Property, ObjectNode and InstanceSpecification names; no exceptions (unless using names to "quote text")! Valid: 'lowerCamelCase' OR 'tla' vs TLA acronym OR 'uCC' vs UpperCamelCase

Also:

Prefer 'UpperCamelCase' (a.k.a. PascalCase) names for Behaviors such as Activities intended for use in CallBehaviorActions, or at least use a 'Capital first letter'; avoid 'all lower case' (as it leads to confusion with lower case Action names)

Prefer anonymous Actions, or if they must be named, prefer code-like 'lowerCamelCase' or completely 'lower case' (if you do absolutely insist on having spaces in action names, but please no other punctuation).

The confusing part properties named 'Part5', 'Part7' and 'Block1' in the specification diagram have been renamed here 'part5', 'part7' and 'block1', and the action 'Action1' has been renamed 'action1'. Some MagicDraw/Cameo tool problems and limitations (may be partly due to spec problems):

Could not reproduce the qualified path name for the allocatedTo compartment on Activity6

The path callout for the allocatedTo is '«part» Block4::Block7::part7'; the spec has '«part» Block4.Part5.Part7'

Could not display the qualified path name Part2:block1in the header for the swimlane

Concerning the spec text:

SysML-1.6: 'Specific behavior allocation of Actions to Parts are depicted in Figure 15-4.'

SysML-1.6: text concerning Figure 15-4 says 'allocation of Actions to Parts are depicted in Figure 15-4' then has an allocation from a part to Activity6.

SysML-1.6: 'The allocation to Activity6 comes from a nested part, and uses the attributes of DirectedRelationshipPropertyPath to specify the path of properties to reach that part. The sourceContext of the allocation is Block4 and the sourcePropertyPath is (Part5).'

SysML-1.6: text concerning Figure 15-4 'The allocation to Activity6'; the allocation is FROM Activity6.

Note also concerning:

SysML-1.6: 'Note that the AllocateActivityPartition, if used in this manner, is unambiguously associated with behavior allocation.'

When it refers to 'behavior allocation' here it includes usage level allocation from an Action to a Property, it does not only mean Behavior (definition level) to Classifier.
