The definitions and labels of BIBFRAME classes and properties can use copyediting. What I have in mind is correcting errors or clarifying terminology, rather than changing the model. Does anyone want to work on it? Examples: bf:Electronic is defined as "Resources organically created, accumulated, and/or used by a person, family, or organization in the course of conduct of affairs and preserved because of their continuing value", but this is a "record series" in the sense used in Special Collections. bf:Tactile has the label "Tactile Expression", but Tactile is a subclass of Instance, and the word "expression" implies it belongs to Work. A better label would be "Tactile Material". Joe Kiegel
