SYSML2_ — Table 5 Attributes Compartment Graphical Notation and Textual Notation does not match

  • Key: SYSML2_-283
  • Status: closed  
  • Source: posteo.com ( Mr. Matthew Johnson)
  • Summary:

    Readers should expect that the textual notation and graphical notation should match as much as possible, including element names.
    The attributes compartment row should at least align on the attribute1 declaration (the definition is different between the graphical and textual notations. I would like to make the case that all of the graphical notation examples should be shown in textual notation, too. If it is worth it to show the graphical notation expectation in the table, it is worth it to show the corresponding textual notation.

    Example of minimum correction in textual notation:
    change:
    attribute attribute1 : Attribute1Def
    to:
    attribute attribute1 : AttributeDef1

  • Disposition Summary:

    Change "Attribute1Def" to "AttributeDef1"

    Presumably the specific example given is from Table 5 in subclause 7.7.2. As noted, Attribute1Def in the textual notation is a typo; it should be AttributeDef1. However, it is not agreed that all the declarations shown in the graphical notation compartment should be repeated in the textual notation. The point of this (and other similar examples) is to show that the declarations in such compartments essentially use the textual notation. So, repeating all the declarations in the textual notation cell doesn't add much, and it ends up being too much text to be formatted reasonably within the cell.
