SYSML17 — Shared parts are still parts

  • Key: SYSML17-145
  • Status: open  
  • Source: Software Centre of Excellence, Rolls-Royce Div. ( Dave Banham)
  • Summary:

    The standard treats non-composite aggregation (white diamond) as the poor cousin of composite aggregation (black diamond) by lumping it into a group of block properties called “references”. (6th paragraph in section 8.3.2.3 Block.) So whilst parts (composite aggregation) have their own compartment, non-composite aggregates have to share a compartment with all of the reference block properties. This also occurs on the IBD with all the types of references being drawn with a dashed rectangular frame. At the very least I would propose that non-composite parts are called reference-parts (as opposed to “owned” parts for the composite ones) and are given their own compartment.
