Hi,

I opened issues related to this before (e.g. #301 more than a year ago) but I think I made a mistake in closing that when opening #397. The simplified prefix.yaml proposal is still desired, but it doesn't fix the big problem that biolink-model.ttl is filled with incorrect prefix expansions. Currently I use this file in a hacky way by manually changing a bunch of identifiers using sed, but it isn't a 100% fix, and it's really inconvenient.
