The PREMIS maintenance activity is responsible for maintaining, supporting, and coordinating future revisions to the PREMIS data dictionary. The Preservation Metadata: Implementation Strategies Working Group, convened by OCLC and RLG, initially developed the PREMIS data dictionary as a specification with the goal of creating an implementable set of “core” preservation metadata elements, with broad applicability within the digital preservation community. Supporting XML schemas allow for implementation of the core metadata element set and are maintained in the Network Development and MARC Standards Office of the Library of Congress.
The PREMIS data dictionary and schema, version 2.0 were issued in April 2008.
