Thank you Amy. That was my understanding as well, but I am glad you confirmed it.

In RDA, anything that is not designated as a "core element" is optional. 220.127.116.11 Recording Relationship Designators does not have this designation. The associated LC/PCC PS reads "LC practice: Provide an authorized access point in the bibliographic record for an illustrator in all cases of resources intended for children. Give the RDA appendix I designator "illustrator" in MARC 700 subfield $e."
In the BIBCO training materials, slide 9 in Module four, captioned "Relationship designators" says "LC policy: decisions in some LCPS; otherwise, cataloger judgment to use."
On OCLC, you will see a wide range of practices in using relationship designators. At Duke, we use them only for special collections.
Hope this helps,

Subject: [PCCLIST] Relator codes
We are implementing RDA original cataloguing soon and I would like to know whether the usage of relator codes (#e) with authors, editors, corporate bodies, etc. is mandatory in RDA? We feel that it is sometimes superfluous (like #eauthor) but would not like to contravene mandatory RDA guidelines. If it is mandatory, could I please have a reference to present to my "critical" colleagues. I have been unsuccessful in finding a clear guideline thus far.
Thank you and kind regards.
