Ø Essentially, it shows that we do not generate any new entailment. Yes – fair enough – I certainly respect that. (Though not sure if it is a clincher, yet.)

My argument in issue 309 (https://github.com/w3c/sdw/issues/309) was about hierarchies in general. I am not against having such hierarchy of activities, I am just questioning whether we need this in SOSA-core compared to another module. I have a nice formal argument for that and will write it up later. Essentially, it shows that we do not generate any new entailment.

That was my proposed ordering – seeing ‘sensing’ as a subset of ‘observing’ to be consistent with OGC usage, where ‘Observation’ covers not only sensing but also forecasting, simulation, human-observing (which is a combination of sensing and application of knowledge). But if we really have a tabula rasa, then we should consider the best terminology and correct hierarchy – maybe ‘estimating’ is a more general term. But definitely the order in that hierarchy should be resolved.

The only change, where I second Simon is, that we should rename Actuation to Actuating. That is then aligned to Sensing and also implies an Activity. The same applies to Observation which I would rename Observing. Although, I am not sure if we need the Observing class in the core if we have Sensing anyway.

I am going to make another series of changes that are a bit bigger and thus will leave them in https://github.com/w3c/sdw/blob/kjanowicz-ssn/ssn/rdf/sosa.ttl for now until we agree on them. Most of this is from our last discussion about procedures and platforms.
