SysMLv1: An ItemFlow without an assigned 'itemProperty' is sometimes informally/casually referred to as an "information flow", especially when applied to an Association (because it is much like a UML InformationFlow), but formally it is a SysML ItemFlow.

Note that to play nicely with SysML flow properties your MUST use a SysML ItemFlow not a UML InformationFlow and the tools help enforce this.

A SysMLv1 ItemFlow without an assigned 'itemProperty' is sometimes informally/casually referred to as an "information flow", especially when applied to an Association (because they are much like a UML InformationFlow with just a 'conveyed' Classifier), but formally it is still a SysML ItemFlow.

In SysML1.7 the permitted Classifier types that may be 'conveyed' are restricted: Finally, note that while the UML InformationItem (which extends Classifier) is in the UML4SysML subset for SysMLv1, it is not explicitly used or otherwise referenced in the SysMLv1.7 spec.
