Re: [Obo-phenotype] pato:quality and bfo:quality

[Melanie C. <mco...@gm...>]

Hi all,

Thanks for the feedback. I agree with the equivalence between  
pato:physical object quality and bfo:quality. I will not use terms  
like pato:duration until this is resolved; instead I will keep a  
placeholder and assert my classes there.

I'd be happy to be included in further discussion as how to best  
address this. Maybe a first step as Alan suggests is coming up with a  
list of things we would like to call "process qualities" and see where  
that takes us. Any suggestion on how to proceed for this - is there a  
wiki page we could use?

Cheers,
Melanie
