SYSML11 — Section: Blocks - BOM properties

BOM properties. In Blocks, BlockProperty, 8.3.2.2, Description, third paragraph, seems to be trying to address the request for bill of material properties. If so, these are properties whose values are all the objects in the composite of a given type. They are derived from all the other block properties of that type. Eg, all the resistors needed to assemble an circuit board.

The referenced section no longer exists in SysML 1.0. The BlockProperty stereotype was removed and its descriptive material incorporated in 8.3.2.2 Block. The previous text referenced by issue is no longer included in the resulting text. The referenced paragraph in the Final Adopted Specification, ptc/06-05-04, previously read:
Parts may be used to show all the components from which a larger system is built. Consistent with UML, however, SysML currently does not provide any means to indicate whether all the parts which make up a larger system are either shown on a particular diagram or contained within a model. Various forms of diagram or model annotation, such as a Diagram Description note as shown in Annex A, may be used to communicate completeness of a diagram or model to a user.
Since this text no longer exists in the 1.0 specification, this issue no longer applies. If there is a need to define a concept of Bill of Material properties within SysML, either by description or by additional metamodel elements, a new issue requesting changes to the current text could be raised and considered within future revisions of SysML.
Disposition: Closed, no change
