Hi Jane -- 

 BIBRFRAME class AccessPolicy is really about policy, intending to reflect current cataloging rules,  rather than access conditions pertaining to specific scenarios.  I think that the use cases you mention are more along the lines of holdings and circulation. 

Even so, AccessPolicy is not an area that we plan to model, but rather, we define the class as a stub so that  descriptions can be supplied based on extensions defined by  external ontologies. There are some candidate ontologies that we are exploring.  

However, the area of holdings and circulation is possibly even more out of scope for BIBFRAME.  Similarly, there would need to be an external ontology developed by subject experts. There are existing protocols, but they would need to be turned into linked data ontologies.  We are also looking into this.
