RDA: Resource Description and Access

Link

RDA: Resource Description and Access is a package of data elements, guidelines, and instructions for creating library and cultural heritage resource metadata that are well-formed according to international models for user-focused linked data applications. RDA has continued to evolve as the global standard for enabling discovery of content and supporting metadata interoperability. The 2018 RDA Toolkit Restructure and Redesign (3R) Project continues that evolution. If you would like to learn more, please check out our blog or contact us at [email protected].
