UML22 — interpreting InstanceSpecification

  • Key: UML22-396
  • Legacy Issue Number: 12427
  • Status: closed  
  • Source: Dell Technologies ( George Ericson)
  • Summary:

    Various readers are interpreting InstanceSpecification differently. One interpretation is that a particular InstanceSpecification specifies a particular instance. A second interpretation is that a particular InstanceSpecification may be used to specify more than one instance. I prefer the second interpretation. This is supported by the Note at the bottom of page 83 that refers to "... such structures."

  • Disposition: Resolved — UML 2.2
  • Disposition Summary:

    It is clear from this sentence: “As an InstanceSpecification may only partially determine the properties of an
    individual, there may actually be multiple individuals in the modeled system that satisfy the requirements
    of the InstanceSpecification.”
    But some of the earlier text seems to imply different - this text is changed.
