error in http://rdaregistry.info/Elements/w/object/P10343

This is wrong according to mapping with LRM and definitions:

Source work should be subproperty of "transformation of": http://rdaregistry.info/Elements/w/object/P10337

Inverses should also be adjusted accordingly

Athena5217,

There is no error. RDA refines lrmer:R22 into 4 different transformation properties: rdaw:P10341 "is transformation by style of", rdaw:P10343 "is transformation by genre of", rdaw:P10345 "is transformation by policy of", and rdaw:P10384 "is transformation by audience of."

This is because of the LRM definition of lrmer:R22: "Relates a work to a previous work from which it was created by changing the scope or editorial policy (as in a serial or aggregating work), the genre or literary form (dramatization, novelization), target audience (adaptation for children), or style (paraphrase, imitation, parody)"

rdaw:P10190 is correctly a subproperty of rdaw:P10343. It is also correctly a subproperty of lrmer:R22.

Thank you for the answer, but your conclusion is wrong because you are starting from an irrelevant premise. Premise that RDA has refined lrmer:R22 into different transformation properties is true, but not relevant to conclusion. Correct premise is about making inferences from subproperties. Every instance of work appropriate for rdaw:P10190 should also be appropriate for rdaw:P10343 because of inference. Source work has definition "Relates a work to a work that is modified to create a new work" ." This modification may not be a change of genre. For example, Chekov play "Uncle Vanya" has source work Chekov play "The Wood Demon." Same genre so not appropriate as "transformation by genre of". Now look at rdaw:P10142, which is subproperty of source work. Every instance of rdaw:P10142 should be appropriate for rdaw:P10343. Yet, this is not true either in practice or definition. Definition of "adaptation of work" does not restrict to genre: "Relates a work to a work that is modified for a purpose, use, or medium other than that for which it was originally intended." Your scope note makes it clear that it inherently a transformation by genre: "This element applies to changes in form or to works completely rewritten in the same form." Thus, Work by Richie Chevat "The omnivore's dilemma" is adaptation of work Work by Michael Pollan "The omnivore's dilemma" because Chevat rewrote Pollan's work for a different audience--children. It is also appropriate to say Work by Chevat "The omnivore's dilemma" is transformation by audience of work by Pollan "The omnivore's dilemma." The same works may have more than one relationship to each other beyond relationships that are subproperties of each other, but your definitions and scope notes for some subproperties of transformation by genre of clearly exclude them from being subproperties of rdaw:P10343 because they do not include a change in genre.

I agree with @Athena5217 that there are anomalies in the semantic hierarchies for these Work-to-Work relationships. The RDA 3R Project discussed these properties many times, in the context of the pre-3R hierarchies and the new treatment of diachronic works suggested by the IFLA Library Reference Model.

There is a fundamental ambiguity in the LRM itself. The scope note for LRM R-22 "is a transformation of" states: "Some transformations may be considered as being only inspired by a previous work". This overlaps with LRM--21 "is inspiration for", with definition "This is the relationship between two works where the content of the first served as the source of ideas for the second". It is unclear if the R-22 scope note is intended to broaden the property semantics to accommodate "transformation" that does not change genre, etc.

The 3R focus on LRM-R21 was confined to application to diachronic works, so the RDA subproperties are for "issue" and "subseries". Subsequent discussions with the IFLA BCM Review Group have indicated that the "inspiration" property is more generally applicable, and I now think that RDA can clarify the hierarchies by explicitly differentiating between "transformation" as involving a change of genre, audience, etc. and "inspiration" as involving no change of genre, audience, etc.

I recommend that the RDA Technical Working Group should review the hierarchies using this basic differentiation and adjust them accordingly. Some minor amendments to definitions and scope notes may help to clarify the semantics.
