Entity process_data_item

• The data value used for a process parameter in a processing activity. For example, where the process considered is a computer program that has a ref process parameter that is the number of iterations of a calculation the program is performing, then the process data item might point to an instance of interprocess data which has an integer value with a value equal to 4 for one particular time this program is run, and 5 for the next time.
