My intuition tells me that "zonular cataract" is a kind of "cataract", and that a "cataract" is a physical entity, not a quality.

They would have to be called something like "zonular cataracticity". The fact that this is beyond awkward is a red flag that this *isn't* something that's naturally defined as a quality. > > Let's keep it simple.

This pattern has worked well for us in defining neurodegenerative phenotypes - the NIFSTD ontologies can be seen as a parallel obo foundry dealing with the neurodegenerative domain, and there are some extremely useful classes there for entities such as cellular inclusions. This avoids getting into all kinds of PATO contrusions. > > I'm neutral as to whether this should be MPATH generalized to mammals. My own choice would be make this as general as possible - pathological cell component classes can be generalized across a wide taxonomic range, and this may be true of tissue level pathogenic entities too. I think we should just go ahead and do it. > > On Dec 12, 2010, at 7:32 AM, George Gkoutos wrote: Remember that the HPO tries to use terms that will be recognizable to our audience. With terms that appear to describe an entity, it helps to silent prepend the phrase "The presence of a", and then everything is a quality. The design pattern you are proposing is interesting but I am not sure I see the benefit that would justify the increased complexity. -peter > >> >> On 12 Dec 2010, at 14:29, Paul Schofield wrote: >> >>> "cataractic" is not really appropriate for PATO.
