Hi Jane -
bf:authorityAssigner from 1.0 is generalized in 2.0. to bf:assigner.
referenceAuthority. Yes, in 1.0 the idea was to be able to designate a principal authority and to distinguish it from one or more secondary authorities. In 2.0 the concept of a principal is discarded. Instead, you can supply multiple agents within a single contribution. (The obvious question is, if you supply two agents for, let’s say author, how do you know whether there are two authors or if they are just different authorities for the same author. The answer is, if there are two authors, supply separate contributions.)
