Entity Relationship Diagram
Nannette Naught of IMT, who serves as document manager and ALA Publishing's technical lead on the project, has created the Entity Relationship (ER) diagram. Tom Delsey, editor of RDA, worked closely with Naught in the project.
An ER diagram is used in software or database development to produce a conceptual data model. An input for development of the functional specification, the ER diagram checks RDA Element Analysis against the FRBR model.
Formatted for printing in 8.5 x 11 inch sheets, the ER diagram is a visual representation of the RDA data model. Below are links to PDF files.
