Hi, For SOSA, I agree with Jano for the exact same reason --> try to use more generic terms that can also be applied to Actuating / Sampling. On the other hand, we could propose a new Option that is similar to Option 3, but retains ObservationValue as a subclass of Result in SSN, we could have ssn:ObservationValue rdfs:subClassOf sosa:Result . ssn:ActuationResult rdfs:subClassOf sosa:Result . etc ? Kind regards, Maxime Le lun. 13 févr. 2017 à 17:59, Krzysztof Janowicz <janowicz@ucsb.edu> a écrit : > I also prefer option 3, with some suggested changes.
