Issue 18525: Clarification required for Copy relationship (sysml-rtf) Source: PTC (Mr. Phillip Astle, nobody) Nature: Clarification Severity: Significant Summary: There's a few issues with the Copy relationship as described in the specification. 1. It's unclear what constraint 3 means. What are subrequirements (nested or derived)? 2. How do you match subrequirements in the slave to subrequirements in the master? 3. There's no constraint on the number of Copy relationships that a slave Requirement can be involved in (e.g. one Requirement could be the slave of two different master Requirements). What happens to the "text" tag if there are multiple masters? 4. There's no constraint stopping a Requirement from being directly or indirectly a master of itself. Shouldn't there be? Resolution: Defer Postponed to the next RTF Revised Text: Actions taken: March 4, 2013: received issue January 3, 2017: Deferred April 6, 2017: closed issue Discussion: End of Annotations:===== m: webmaster@omg.org Date: 04 Mar 2013 10:48:24 -0500 To: Subject: Issue/Bug Report X-Brightmail-Tracker: AAAAAA== X-Brightmail-Tracker: AAAAAA== ******************************************************************************* Name: Phil Astle Employer: Atego mailFrom: phil.astle@atego.com Terms_Agreement: I agree Specification: OMG Systems Modeling Language (OMG SysML.)
