PCC Relationship Designator Guidelines Task Group Report

The PCC Relationship Designator Guidelines Task Group Report was recently published.
It has always been one of the main functions of the library catalogue to relate resources to other entities. Main and added entries express relationships between persons or organizations and the resources for which they are responsible, and other devices such as analytical added entries, uniform titles, linking entries, and series headings are all ways of expressing defined sets of relationships among resources themselves.

The relationship designators in RDA should be seen as an evolution of these devices. But where MARC captures a relatively limited set of relationships, largely those applicable to traditional library collections, the RDA relationship designators establish a framework to express a potentially much richer set of relationships. In addition, the linked data environment in which RDA relationship designators are intended to be implemented may eventually offer more powerful ways of handling relationships.
