Like a scientist's written account before the digital age, it records the means and circumstances of the capture of digital information from a “real world” subject, tracking all the events associated with the processing of this information into a digital representation.

This technical white paper compares the functional roles of the two standards for metadata encoding and the management of interoperability and information integration in heterogeneous, distributed digital library environments. These standards are: CIDOC CRM (the Conceptual Reference Model of the International Committee for Documentation of the International Council of Museums); and METS (Metadata Encoding and Transmission Standard). The paper investigates the ways in which both standards can be optimally used in combination. The report calls upon managers and practitioners to support decisions about the deployment of these standards and to serve as guides for the effective use of both standards. The paper was commissioned and financed by Cultural Heritage Imaging with majority funding from the US Institute of Museum and Library Services' (IMLS) National Leadership Grant Program (Award Number LG-25-06-0107-06). Additional funding was provided by charitable contributions to Cultural Heritage Imaging.
