environmentalMedium should be part of the Samples entity

[ericcrandall]

Currently in Events. Defined as the medium displaced by the sample, so is more relevant to the sample than the sampling event.

[jdeck88]

Consider a duck... environmental medium could be water if it is floating on water or swimming when captured... Or it could be air if shot of the air. Thus, the medium is dependent more on the place and time that the individual (or sample) was isolated from the environment.

[ericcrandall]

Right, but hunters or biologists who are collecting ducks on a single expedition might shoot them in the water or shoot them in the air, and so the field could be different per sample.

Also, in the datathon we have often been using | delimiters for multiple media displaced by a sample - plants being the most obvious one. They (almost) always displace "soil | air".

[jdeck88]

environmentalMedium is a property of the broader environmentalContext, which includes similar terms like habitat, elevation, and temperature which we have grouped generally into properties of the event entity. Those attributes describing the conditions surrounding the materialSample that was isolated from the natural world

Re: the second point about multiple environmentalMedia is interesting. I created a new issue #62

Am closing this issue for now but feel free to re-open if the first point presents some urgency!
