Comment #9 on issue 42 by ja...@overton.ca: Add annotations to 'derives from' and 'derives into' https://code.google.com/p/obo-relations/issues/detail?id=42 I agree with David on Melanie's case. Michel raises anther tricky case. I'm sure there's literature on this, but I don't know it. The "t3 derives from t1+t2 (an aggregate)" strategy can work. It might be the best fit for the zygote case, since both egg and spermatozoon contribute (biologically) significant portions of the matter and the zygote can't exist without both: "this zygote derives from this (aggregate of) egg and spermatozoon". I don't think this strategy works as well for the tree graft example, since the tree can continue to exist without the graft. So I wouldn't use 'derives from' here. With just ROCore, maybe the graft becomes 'part of', but full RO might have a better relation. This is a fuzzy term that raises lots of hard questions about identity and change. I agree with David that a more general term would be useful. But I'm happy with the improvements we've got to the existing term, and I think we should leave the bigger questions for another tracker item. -- You received this message because this project is configured to send all issue notifications to this address.
