Rationale Required to model the constraints that need to be adhered to.
Resolution: Add Source-target constraints to NeedlineExchange Raise issue to change NeedlineExchange to OperationalExchangeAction-Fatma to write description of usageFatma's description to be added to the Exchange descriptions in the specification.PA 17/2/2009 If we rename NeedlineExchange to OperationalExchange then we also need to rename NeedlineExchangeItem to OperationalExchangeItem.Also need to add constraints to OperationalActivityEdge/FunctionEdge that states if the stereotype is applied to an ObjectFlow and the edge is connected to an Exchange, the conveyed item and the pin types need to be consistent/compatible.

Action-Fatma to write description of usage
Fatma's description to be added to the Exchange descriptions in the specification.

PA 17/2/2009 If we rename NeedlineExchange to OperationalExchange then we also need to rename NeedlineExchangeItem to OperationalExchangeItem.
Also need to add constraints to OperationalActivityEdge/FunctionEdge that states if the stereotype is applied to an ObjectFlow and the edge is connected to an Exchange, the conveyed item and the pin types need to be consistent/compatible.
