Re: Pull request for ACTION-308: Implement the operating and survival range for actuators in ssn

Agreed. Will be an action item I'll be glad to take care of.

Please note I'll be 10min late to the meeting today, I'm on my way home

Yes, very good.

Just as an example, the same is true for the other classes. If we want
to use a consistent style, Sensor and so forth have to be in upper case
and the examples should not be in the definition but in an skos:example
triple. See, for example, the sosa.ttl file.

Great work!
