BPMN2 — Correlation on message flow and choreography activities

  • Key: BPMN2-263
  • Legacy Issue Number: 15069
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    Should be able to specify correlation directly on message flow and
    choreography activities, without the overhead of conversations.

  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Choreography activities are a way of grouping message flow and should
    have correlation like other message flow grouping constructs. Message
    flows themselves do not need correlation, because correlation only works
    if the same key values are in more than one message flow, as identified
    by message flow grouping constructs.
    Remove Subsection 12.3.3 (Correlations) and the sentence in it.
    In Figure 12.6 (The metamodel segment for a Choreography Activity) add
    the CorrelationKey metaclass with a unidirectional association to it
    from ChoreographyActivity. This association has multiplicity 0..1 on
    the ChoreographyActivity end and * on the CorrelationKey end. The
    association end on the CorrelationKey end is named correlationKeys, which
    has composite aggregation (the black diamond appears on the opposite
    In Table 12.2 (Choreography Activity Model Associations) add a row at
    the end:

    • correlationKeys : CorrelationKey [0..*]
      This association specifies correlationKeys used by the message flow
      in the choreography activity, including subchoreographies and called
      In Table 12.11 (ChoreographyActivity XML schema), after the
      participantRef element attribute, insert on a new line:
      <xsd:element ref="correlationKeys" minOccurs="0" maxOccurs="unbounded"/>
