Metadata Basics



Metadata crosswalks translate elements and values from one schema to those of another. Crosswalks facilitate interoperability between different metadata schemas and serve as the a base for metadata harvesting and record exchange.

Below are examples of crosswalks that have been developed between widely applied metadata standards.

Multiple Standards Crosswalk

Crosswalks can cover the mapping relationships between more than two schemas. An example is the Getty Institute's crosswalk in which 12 schemas, including VRA Core, MARC, EAD, and Dublin Core, all crosswalk to CDWA.
