Carsten, thanks for the suggestions. We have a constant struggle between accomodating messy note-like data in our current catalog, and the dream of controlled vocabulary (and links to resources) in use across the board. Right now there are not enough resources to link to, although we continue to add them id.loc.gov. ECPO looks interesting. I suspect going forward there might need to be a literal version and a uri version for many properties in BIBFRAME, but two ways to do something has its own pitfalls.

Subject: [BIBFRAME] enumeration and chronology + ranges
In the BIBFRAME vocab I stumbled upon the property bf:enumerationAndChronology  with a Literal as range.
Have you ever thought about getting more explicit like our  approach with the Enumeration and Chronology of Periodicals Ontology (ECPO) ?
I have taken a quick look at the bf:HeldItem class . From my point of view there are some other property ranges you might rethink, like for bf:circulationStatus and bf:subLocation (I suspect more like these). Both instances might also be expressed as resources.
