Activities, entities and involvements like Usage and Association have in a broad sense all durations. However DM only talks about activity durations, and the others have/are 'events', so we should keep the focus there for now, and rather raise it as a requirement to DM if we can think of a good use case. >> For the domain, Association and Delegation are different from other >> Involvements in that they are not expected to have time information, is this >> because we do not view them as instantaneous events? > I'd be curious to hear an answer to this. I would assume they are non-empty durations in almost every use case. -- Stian Soiland-Reyes, myGrid team School of Computer Science The University of Manchester
