Dear All,

" Of course, this will never reach the precision of costly
scientifically-led
risk analysis. But maybe better than nothing, mainly in data-poor
environments? And could always be enriched in the future.
"

Why not simply use the existing ontologies from these 'scientifically-led
research projects'? There are so many so many so many ontologies out there
already that it's really a waste of time for a dispersed group like this to
try and make their own. Plenty of these are already public, notably the EC
ones, and they're exhaustive and they're currently in use and they're
usually quite simple :-) How about the CAST ontology?

Warm Regards,

-Joseph.
