I don't like the idea of mapping RDA creator element to MARC 100/110/111, saying that "If it's 1XX, that means it's a creator." That is not the meaning of the 1XX field, any more than the presence of a name at the beginning of an RDA authorized access point for a work/expression means that the entity so named is a creator. It is true that in the vast majority of cases they are "creators", even if it's because RDA maintained the AACR "choice of main entry" practice by declaring many entities to be "considered to be creators" in 19.2.1.1. But it is in correct to say that defendants, complainants, or indictees (6.29.1.24-6.29.1.26) are creators even though they might end up being tagged as 1XX; they are "Other Persons, Families, or Corporate Bodies Associated with a Work" (19.3 and I.2.2).
In RDA terminology, the meaning of MARC 100/110/111 in a bibliographic record or name/title authority record is essentially "name portion of the authorized access point for a work or expression".

From: Resource Description and Access / Resource Description and Access [mailto:RDA-L@LISTSERV.LAC-BAC.GC.CA] On Behalf Of Ed Jones Sent: Tuesday, March 12, 2013 12:16 PM To: RDA-L@LISTSERV.LAC-BAC.GC.CA Subject: [RDA-L] Coding subsequent creators in MARC 21 Bibliographic While the RDA "creator" element can be mapped to the MARC 1XX field, this mapping breaks down for works involving more than one creator, since the 1XX field is not repeatable. At present, subsequent creators are mapped to MARC 7XX, which is also used for contributors, so they can only be identified by including a (more specific) relationship designator. Consequently, unless a relationship designator has been included in a given MARC 7XX, there is no way to accurately map the data to a record syntax such as Dublin Core or a FRBR-based syntax that routinely distinguishes creators from contributors. One way around this conundrum would be to bring back a couple of second indicator values that were formerly valid in the 7XX fields. These values distinguished what were then called alternative entries (value=0, definition=added entry can be sub-filed by title [essentially a creator]) from secondary entries (value=1, definition=added entry can be sub-filed by main entry [essentially a contributor]). Restoring these values in MARC 21 Bibliographic would enable us to distinguish creators from contributors without the need to supply a more specific relationship designator in each case. It would also give equivalent status to all creators, which is important if one is looking for all the works of a given creator (rather than those works on which he/she just happens to be named first).
