Re: Notation Question in the examples on SOSA/SSN

Hi all,

I am watching with interest to see what the consensus is regarding "FoI-Specific ObsProps" or "neutral ObsProps".

I'm happy to assist with RDF formulation of things if needed. I have a lot of work going on at the moment involving biodiversity "parameters" (ObsPros) such as those listed here, http://linked.data.gov.au/def/tern-cv/5699eca7-9ef0-47a6-bcfb-9306e0e2b85e, and I'd like to see how to mesh our current practice with the canonical examples here.

We now have a database of 70+ million observations of species occurrence and multiple mullion secondary observations of properties of the species (tree hight, specimen colour etc.) so plenty of material to play with in line with the example pattern being formulated here.
