Re: Suggested Concepts for Charter

Yes, I agree with you in the "adjacent_to" property. I was more concerned
about the "located_in" property, which I associated to explicit coordinates
of the sensor or buoy at a certain time, but as Paul explained it might be
better a recommendation than a property of the core.
