Accommodating RDA is an active area of development. A few of the early experimenters mentioned in the announcement are, in fact, investigating how the BIBFRAME model, while remaining content standard agnostic, can meet the needs of RDA. It is worth recalling that the "broad accommodation of content rules and data models" was the first requirement listed when the General Plan was announced in October 2011 [1]. The "accommodation of RDA" was chief among the content rules listed. Nothing has changed with respect to this requirement.

It may be that an RDA Work and RDA Expression are bound up in a BIBFRAME Work, with BIBFRAME Instance being most closely associated to RDA Manifestation, and the notion of an Item captured as a BIBFRAME Holding, all as you surmise. This is where qualitative community discussion about these important issues is crucial. Thanks for getting it started.

Cordially,

Kevin
