Hi Jun, > Would you also expect agents to have states, aka resources? Even process (execution) have states (initiated/suspended/terminated).

They are not incompatible requirements (simple and being able to describe their provenance) - I am not sure what are the "structures associated with resources". Overall, I would like to be guided by the requirements of our journalism example (and its subsequent extensions or other examples). Thanks.
