Yes, but I think we were thinking more that a procedure uses a device, during an activity.

When describing the agents of observation, it depends how close you want to look. There are multiple layers of encapsulation. That was probably the motivation for bundling them together in SensorML and O&M, but SSN chose to be more careful about distinguishing physical devices from workflows – which I certainly understand as well.

The word ‘process’ is overloaded, and in particular is used in contradictory ways in BFO and O&M, and SensorML uses it in both ways. So now I prefer to avoid it altogether.

Sorry I missed the call today. So a device “runs” (l:n) a procedure in / during (1:n) a process?

I’ve put some notes and a diagram explaining my understanding of the consensus from today’s call here https://www.w3.org/2015/spatial/wiki/SOSA_Ontology#Procedures_vs_Devices




Note

1.      I have adjusted the names of the classes to avoid ambiguity between the re-usable things and the events when they are used

2.      I have not yet implemented this in SOSA-Core – its just a proposal for now.
