In a NISO webinar Wednesday Eric Miller suggested that there would need to be an RDA profile built on top of Bibframe before many of the RDA questions could be addressed. This leads me to wonder if we should be thinking of Bibframe as an alternative to ANSI Z39.2 and not really to MARC 21. The work of building an RDA profile for Bibframe could be taken up by the new ALA metadata committee that will replace MARBI soon. That said, I agree with Kelley that Bibframe needs to get the basic relationships right. Even at the Bibframe level, the relationship between Work and Instance will need to be more complex than one-to-one only. That should be something profiles built on Bibframe can determine, based on how they specify different kinds of work and different kinds of instance. Stephen On Thu, Jan 24, 2013 at 11:40 AM, J.
