SYSML16 — SysML: Interaction diagram and Data-based comm of SysML

  • Key: SYSML16-14
  • Legacy Issue Number: 11627
  • Status: closed  
  • Source: Commissariat a l Energie Atomique-CEA ( Dr. Sebastien Gerard)
  • Summary:

    Here is a question on the usage of sequence diagrams with SysML, more specially with blocks that communicate via flow ports.

    Within UML, Message is associated with signature of either a Signal or an Operation (see constraint 2 on Message meta class, p. 492 of the UML2 superstructure spec.).

    In SysML, blocks introduce an alternative for communication between blocks w.r.t. to usual UML2 composite structures: flow ports are basically dedicated to support data-based communication between blocks in contrast of UML2 that does not support such kind of communication between composite structures.

    In this case, a Message within an interaction should be able to refer either a DataType, a Block, a ValueType if the communication happen between two atomic flow ports, or to a FlowSpecification if the communication happen between two non-atomic port.

    I did not see anything related this issue within the SysML spec. Do I miss something or is it something missing in the SysML doc?
