> does this always apply PM2.5 in ENVO for example? You're right: in this case there's a class linked to a threshold defined in environmental monitoring regulation. This came from...

I don't know @nlharris @cmungall The need is simple and valid: we need a way to say that instances of one class typically have increased/decreased magnitudes of some quality relative...

I'm creating "derives from part of" in ENVO for the moment. I only see "derives from" in RO, and then "derived by..." classes

Thanks @balhoff ! BSPO has many terms that ENVO could use - would there be a way to generalise its content? Rebranding it perhaps?

The `in deep part of` quality isn't quite right, as we're targeting the idea of `RO:located in`. For now, I think we can use relations and do the job. However,...

Proposed def: "A positional quality inhering in a bearer by virtue of that bearer being located within another entity." I'm not sure if we'd want to stick to material entities...

Argon-39 is missing from CHEBI for the Transient tracers EOV semantics. Requested in the CHEBI tracker https://github.com/ebi-chebi/ChEBI/issues/3786

As we deal with environments rather than spatial paths, I'm going to represent this as an ecological corridor. Think the sub-system of a biosphere through which an ecological population or...
