  1. OMG Issue

SYSML16 — ISO-80000 ValueType stereotype applications have wrong unit and quantityKind values

  • Key: SYSML16-155
  • Status: closed  
  • Source: Airbus Group ( Yves Bernard)
  • Summary:

    The ISO-80000 library has numerous instances of the SysML::ValueType stereotype applied on data types. They are intended to specify the corresponding units and quantity kinds.

    According to SysML, both unit and quantityKind properties of the ValueType stereotype shall be InstanceSpecifications.

    However in http://www.omg.org/spec/SysML/20150709/ISO-80000 all of them refer to the data type the stereotype is applied to rather than to the expected instance specifications. This could result from a bug in the ID generation algorithm used for SysML 1.4

    Example

    <SysML.Blocks:ValueType xmi:id="ISO-80000.package_packagedElement_ISO80000-9_Physical_Chemestry_and_Molecular_Physics.package_packagedElement_Quantities.package_packagedElement_amount_of_substance_concentration.dataType_packagedElement_amount_of_substance_concentration_u0028zettamole_per_cubic_metre_u0029.stereotypeApplication_SysML.package_packagedElement_Blocks.stereotype_packagedElement_ValueType">
        <base_DataType xmi:idref="ISO-80000.package_packagedElement_ISO80000-9_Physical_Chemestry_and_Molecular_Physics.package_packagedElement_Quantities.package_packagedElement_amount_of_substance_concentration.dataType_packagedElement_amount_of_substance_concentration_u0028zettamole_per_cubic_metre_u0029"/>
