Issue 7247: Connector - "provided Port" and "required Port" not defined Constraint 1 (uml2-rtf)
Source:  (, )
Nature: Clarification
Severity: Significant
Summary: Connector - "provided Port" and "required Port" not defined Constraint 1, "[1] A delegation connector must only be defined between used Interfaces or Ports of the same kind, e.g. between two provided Ports or between two required Ports." uses the concepts "provided Port" and "required Port". Neither of them is defined in the spec. Furthermore, a Connector is not expected to be defined between Interfaces, but an Association is. A Connector is defined between ConnectableElements whose specializations are Property, Port, Parameter, and Variable, but not Interface. I suggest to replace Constraint [1] with "[1] A delegation connector must only be defined between a ConnectableElement (i.e. a Port) of the component and a ConnectableElement (i.e. a Property or a Port) of one of its internal parts."

Issue 7247: Connector - 'provided Port' and 'required Port' not defined Constraint 1 


Issue summary 
Connector - 'provided Port' and 'required Port' not defined Constraint 1, '[1] A delegation connector must only be defined between used Interfaces or Ports of the same kind, e.g. between two provided Ports or between two required Ports.' uses the concepts 'provided Port' and 'required Port'. Neither of them is defined in the spec. Furthermore, a Connector is not expected to be defined between Interfaces, but an Association is. A Connector is defined between Connectable Elements? whose specializations are Property, Port, Parameter, and Variable, but not Interface. I suggest to replace Constraint [1] with '[1] A delegation connector must only be defined between a Connectable Element? (i.e. a Port) of the component and a Connectable Element? (i.e. a Property or a Port) of one of its internal parts.'
