There’s currently no relationship to specify that a given edition was read/narrated by a given Author entity/ies. E.g., "(Author) narrated (Edition)"/"(Edition) was narrated by (Author)".

I feel like this probably makes most sense on Edition since an audiobook Edition would likely belong in an Edition Group with non-audiobooks that thus would not have a narrator.

I don’t know if narrators should also be specified as part of the Edition specific Author Credit, but regardless, this feels like it should (also) be a relationship.
