RDA provides methods to explicitly document types of relationships between the manifestation being described and the access points of agents responsible for the creation of or contribution to the work and/or expression embodied in the manifestation. RDA also allows for structured relationships between the work, expression, manifestation, and/or item and other works, expressions, manifestations, and items. These relationships are fundamental to the entity-relationship model put forth in the IFLA-LRM (International Federation of Library Associations & Institutions-Library Reference Model) theoretical model.

This workshop provides instructions on identifying and constructing access points for works, expressions, manifestations, and items and the application of relationship designators to various authorized access points using the MARC 21 Format for Bibliographic Data (MFBD).

This session assumes some basic knowledge of cataloging and the MARC 21 Format for Bibliographic Data. Sessions are geared to both copy and original catalogers at all levels, and they are still accessible for those who are just starting to learn. Access to the RDA Toolkit and ClassWeb tools are not required. Public and academic library staff members will be interested in these workshops because they will be able to identify the attributes necessary for quality MARC records supplied by vendors and understand some of the new and changed vocabularies that support linked data. Special library staff will be interested in these workshops because they will be able to distinguish between core attributes and special attributes that serve their users.

Learning Outcomes: Participants will be able to apply the RDA instructions for the construction of general access points for works, expressions, manifestations, and items; for the application of relationship designators to the access points; and for the methods to encode these relationships in the MFBD. Participants will be introduced to the concept of aggregates.
