1. A computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to recognize an order item, the recognizing comprising: defining an order item specification comprising a recognition property and a dynamic parameter property; receiving an order item of an order, the order item comprising a key that uniquely identifies a conceptual model entity and one or more arbitrary parameters, each arbitrary parameter comprising a parameter name and a parameter value; extracting the key from the order item; storing the key within the recognition property; identifying the conceptual model entity based on the recognition property; and dynamically binding one or more parameter values from the arbitrary parameters to the dynamic parameter property based on the identified conceptual model entity.
