I have produced a mapping of RDA resource relationships (Appendix J) to BIBFRAME, which is attached and also available at http://www.lib.washington.edu/msd/pubcat/ld. There are four files, one for each WEMI class.
Note that the highest level relationship in each category is not mapped since it is not likely to be used in practice.
Here are comments on BIBFRAME based on a review of the mapping and corresponding BIBFRAME properties.
BIBFRAME does not handle well the relationship between resources that RDA terms “complemented by”: a work paired with another work without either work considered predominant. Examples are a musical work and a libretto, a screenplay and a motion picture, or a motion picture and music. The property bf:accompaniedBy works well for appendices, addenda, errata, etc., but not for works complemented by other works. An additional BIBFRAME property is needed.
There is a question how to handle prequels. In terms of production date, a prequel succeeds the original (bf:succeededBy) but in terms of the date of the story line, it precedes the original (bf:precededBy). What is best practice?
Verb tense should be consistent across property names so bf:absorbed should be bf:absorbs.
The subproperty assignments of bf:translation and bf:translationOf appear to be reversed. bf:translation should be a subproperty of bf:hasDerivative, and bf:translationOf should be a subproperty of bf:derivativeOf.
The property bf:otherEdition was not used in the mapping and it is not clear what function it serves.
Thanks to Theo Gerontakos for reviewing the mapping.
