Most relator terms in an RDA MARC record will appear in a ǂe of the access point field. For example:
100 1_ ǂa Snicket, Lemony, ǂe author. 700 1_ ǂa Klassen, Jon, ǂe illustrator. 710 2_ ǂa IBM de Chile, ǂe sponsoring body.
The added entry field for Meeting names, 711, uses ǂe for a different element (“subordinate unit”), so in that field, the relator term goes in a ǂj. For example, if you want to add an access point for a conference as a sponsoring body, it is encoded like:
711 2_ ǂa AAPG Convention ǂd (1992 : ǂc Calgary, Alberta), ǂj sponsoring body.
Similarly, subfield ǂj is also used for the relator term in 111, 611 and 811.
