KERML_ — Colloquial use of "Item" in KerML confusing against SysML

  • Key: KERML_-107
  • Status: open  
  • Source: Ansys Government Initiatives ( Mr. Richard Page)
  • Summary:

    The term "Item" in the KerML specification is colloquial and pre-existed the introduction of "Item" as a SysML concept. In SysML "Item" is restricted to an Object (Occurrence), disjoint with DataValue. This means that "Items" in SysML cannot be DataValues (for attributes). This is NOT what is specified in KerML, despite the use of the term "Item" there.

    Thus, "ItemFlow" in KerML section 8.3.4.9.3 does not correspond at all to "Items" in SysML.

    Because users are looking to KerML for descriptions of the foundational semantics underneath SysML, SysML users and vendors will be looking at KerML to understand semantics around flows at the KerML level to inform how to interpret SysML. Because of this, the use of "Item" as a term in KerML is confusing.
