SYSML2_ — Missing graphical notation for n-ary connection def and usage

Open Closed All
  • Key: SYSML2_-23
  • Status: closed  
  • Source: DEKonsult ( Mr. Hans Peter de Koning)
  • Summary:

    BNF production is missing for n-ary connection def and connection usage as in examples shown in the representative notation table in 7.13.1 Connections Overview. Must be fixed in 8.2.3.13.

    Check all examples of n-ary connections (including causation and requirements derivation) to replace arrowheads with bolded end names. Connections of 3 or more ends only have target ends, no source ends, see KerML spec clause 7.4.5.

    Missing graphical notation for n-ary connection def and usage

    The issue was already addressed and resolved as part of resolution SYSML2-277 for issue SYSML2-47 in Ballot #5 of the SYSML2 FTF. No further updates are needed.

    However, a graphical BNF production for n-ary ConnectionDefinition is still missing, and raised in SYSML2_-247 .
