Issues Descriptions

Verb Concept Role Designation

  • Key: SBVR16-61
  • Status: open  
  • Source: Trisotech ( Ron Ross)
  • Summary:

    Issue:
    In the current definition of verb concept role designation, the phrase “is recognizable in use in the context of another role of the same verb concept” is obscure. As currently worded, the definition also precludes designations for unary verb concept roles. In addition, the definition fails to express the inherent and necessary linkage in meaning between a verb concept role designation and the verb concept itself. Finally, figure 11.2 is misleading because it omits “noun concept” as being the more general concept of “role”.

    Resolution:
    1. Change the definition of ‘verb concept role designation’ to:
    designation that is of a verb concept role and that has an expression whose representation of the verb concept role is meaningful only in the context of the verb concept that has the verb concept role
    2. Add “noun concept” as being the more general concept of “role” in figure 11.
    3. Add these examples before the existing example for the entry:
    Example: In the verb concept "party rents property", “renter” might be the verb concept role designation for party, and “rented property” might be the verb concept role designation for property.
    Example: In the unary verb concept "shipment is late", “late shipment” might be the verb concept role designation for shipment.

Use of 'Classifies'

  • Key: SBVR16-62
  • Legacy Issue Number: 19902
  • Status: open  
  • Source: Trisotech ( Ron Ross)
  • Summary:

    Problems:

    1. By my count, the verb "classifies" appears 8 times in SBVR in stylized font, indicating there should be a defined verb concept for it. However, I do not find one.

    2. These 8 instances do not appear to me to necessarily conform to a single meaning. They should be reviewed if kept in stylized font.

    3. Issue 15-28 (was 19631) "Definition of 'categorization scheme contains category'" addressed a minor wording improvement for this verb concept. It has been noted that "divides" in that definition should probably be replaced by "classifies". However, that point was deferred to this new issue.

    Discussion:

    In SBVR, “classification” is a relationship between two concepts. That meaning is generally not what 'classification' means in natural language. Any formal definition of "classifies" should align itself with the existing meaning of "classification". Doing so, however, is likely to result in further misinterpretations.

    Recommendations:

    1. Remove the styling from the 8 existing uses of 'classifies'.

    2. Change "divides" in the definition of "categorization scheme contains category" to "classifies" (unstyled).

Rules Based on Implications

  • Key: SBVR16-63
  • Legacy Issue Number: 19900
  • Status: open  
  • Source: Trisotech ( Keri Healy)
  • Summary:

    On physical page p. 45 of Version 1.4 of SBVR, the Necessity listed under the entry for Implied Characteristic includes ”logical implication” as a defined (styled) term. However, there is no definition entry for “logical implication” in SBVR 1.4.

    Logical implications underlie a very important form of (business) rules. A standard covering rules from the business perspective is incomplete without appropriate treatment. Such treatment must fully explain what “logical implication” means ­ and does not mean ­ selectively for both behavioral and definitional rules. SBVR needs to address the fundamental semantics of rules based on implications.

Example for Verb Concept Role

  • Key: SBVR16-59
  • Status: open  
  • Source: Trisotech ( Ron Ross)
  • Summary:

    This core SBVR concept needs an example.

    Example: Eu-Rent has cars that people rent. The verb concept “rents” includes placeholders for two verb concept roles, one for the person renting and one for the car rented. Two verb concept role designations are specified for these verb concept roles: “renter” and “rented car”, respectively.

Example for Situational Role

  • Key: SBVR16-60
  • Status: open  
  • Source: Trisotech ( Ron Ross)
  • Summary:

    This entry needs an example.

    I suggest the following ...

    Example: The situational role 'negotiator' is the part a person plays, or function a person assumes, in the situation 'resolution of contractual disputes'.
