According to DCM Z1, 5XX See Also From Tracing - General Information:
"LC/PCC catalogers applying RDA instructions may use subfield $i in conjunction with subfield $w code 'r' for relationship designators. When applying RDA relationship designators in 5XXs, supply terms from Appendix I, J or K; capitalize the initial letter of the term and follow the term with a colon.
"Until a decision is reached by the PCC Policy Committee on the use of relationship designators in authority records, LC/PCC catalogers may continue to use the subfield $w codes "a" (earlier) and "b" (later) or optionally use the appropriate relationship designators from Appendix K to provide relationship links between corporate entities (510 or 511)."
