organizations involved in creating the record, assembling biographical data relating to those creators, and applying a standard such as Resource Description and Access to the names so that the names can be easily referenced between institutions. These authority records can then either be incorporated into metadata of an archival records or separate authority records can be created, which are then linked with the archival materials. Relation to Other Standards While the first edition expanded on the basic rules for describing archival material that are found in chapter 4 of the deprecated library cataloging standard, Anglo-American Cataloguing Rules (AACR2), the second edition of DACS more closely relates to AACR2's successor, Resource Description and Access (RDA). DACS serves as the US implementation of international archival descriptive standards such as ISAD(G) and the International Standard Archival Authority Record. It also provides crosswalks from DACS to MARC, Encoded Archival Description (EAD), RDA, and Encoded Archival Context (EAC-CPF). DACS specifies only the type of content, not the structural or encoding requirements or the actual verbiage to be used; it is therefore suitable for use in conjunction with structural and encoding standards, such as MARC and EAD, and with controlled vocabularies such as Medical Subject Headings, Library of Congress Subject Headings, Art & Architecture Thesaurus, and so on.
