RSC/RelationshipWG/1 8 August 2016 Page 1 of 31 To: RDA Steering Committee From: Gordon Dunsire, Chair, RSC Relationship Designators Working Group Subject: RDA models for relationship data Abstract This paper discusses how RDA accommodates relationships between instances of different entities. The paper makes some general recommendations for developing RDA to improve its accommodation of relationship data. It also proposes specific revisions to RDA Toolkit. This paper was developed in collaboration with the RSC Technical Working Group. Justification A task (#1) for the RSC Relationship Designators Working Group in 2016 is to investigate the requirements and review the treatment and structure of relationship designators in RDA Toolkit, clarify the relationship of designators to elements, and clarify the requirements of same-entity and cross-entity designators, building on 6JSC/AggregatesWG/1. An additional task (#2) is to prepare a proposal/discussion paper for the organization of designators between Persons, Families, and Corporate Bodies in Appendix K, taking into account 6JSC/ALA/43 and JSC responses. An additional task (#3) is to review the use of parenthetical entity qualifiers and investigate alternative approaches to designator labels. An additional task (#4) is to propose guidelines on submitting new relationship designators, including labels, definitions, scope, and hierarchies. A task (#7) for the RSC Technical Working Group in 2016 is to investigate how RDA accommodates relationships between instances of different entities, in collaboration with the RSC Relationship Designators Working Group, and prepare a proposals/discussion paper. This paper is the outcome of task #1, and partially fulfils tasks #2, #3, and #4, for the RSC Relationship Designators Working Group, and fulfils task #7 of the RSC Technical Working Group. Scope
