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.)

Hi Simon,


But definitely the order in that hierarchy should be resolved.

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.

Currently Sensing is a subclass of Observing (or Observation), which is a subclass of Activity. 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 proposal we arrived to now looks good to me.

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 made some cosmetic changes and pushed them to github. 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.

I’ve just pushed an update to the SOSA Core ontology
https://github.com/w3c/sdw/tree/simon-ssn/ssn/rdf

in particular https://github.com/w3c/sdw/blob/simon-ssn/ssn/rdf/sosa.ttl


This includes the hierarchy shown on the wiki page https://www.w3.org/2015/spatial/wiki/SOSA_Ontology


I’ve cleaned up the class names a bit, and added documentation on all elements.
