SYSML17 — SysML Issues on Item Property values in an IBD

The SysML spec does not give any notation for (or example of) specifying the values of an item property participating in an item flow. For example, if water flows in multiple places in the distiller, each should be able to have a specified temperature and dissolved matter % (perhaps as distributions).

Perhaps a variant of a property specific type would work, perhaps a callout approach would work.

It possible, it would be desirable to allow for multiple item properties:item flows to have the same name within an ibd, as this would be a natural modeling approach (e.g., all the pipes covey the same thing, but with different values).

Proposal: SysML Issues on Item Property values in an IBD

New features are out-of-scope for SysML 1.7 and should be covered by SysML v2 if necessary for SysML.
