Remove classes bf:AppliedMaterial and bf:BaseMaterial. #28

Closed sfolsom closed 3 years ago

sfolsom commented 6 years ago

Justification: bf:appliedMaterial and bf:baseMaterial are sufficient.

We do not believe that BaseMaterial and AppliedMaterial are types of things. A material instance (e.g. brass) is simply a Material, and it may be used as the base material or the applied material in specific cases. A material which is a base material to one resource may be the applied material of another.

[This recommendation was made on behalf of the LD4P Art & Rare Materials BIBFRAME Ontology Extension (https://github.com/LD4P/arm).]

This was rejected at this time. We did create the more abstract bf:Material and made these existing classes subclasses of bf:Material.

Implementers should migrate to the more abstract class, but with the more specific properties.
