Systems Modeling Language (SysML) 2.0 FTF 2 — Open Issues - OMG Issue Tracker

Key: SYSML2_-200

Status: closed

Source: International Business Machines ( Mr. Eran Gery)

Summary:

GBNF and notation tables only cover a generic "loop action" which is not aligned with the textual syntax that has 3 specific structured actions:

while loop action
for loop action
if/else action

Each one of the above has a specific textual syntax, that the graphical syntax should align with, to enable proper graphical modeling of actions.

Reported: SysML 2.0b2 — Sun, 12 May 2024 16:43 GMT

Disposition: Resolved — SysML 2.0b4

Disposition Summary:

Structured actions not properly covered by GBNF and notation tables

This resolution adds proper graphical notation for the structure actions, WhileLoopAction, ForLoopAction, and IfAction/IfElseAction to the graphical BNF if subclause 8.2.3. It also correspondingly updates related examples in various subclauses of Clause 7.

(Note that the productions for while-loop-action-name-compartment, for-loop-action-name-compartment, and ifelse-action-name-compartment are consistent with the proposed resolution ~~SYSML2_-198~~.)
