The Australian METS Profile describes the rules and requirements for using METS as an exchange format to support the collection and preservation of and access to content in Australian digital repositories. The profile was developed as part of the Australian Partnership for Sustainable Repositories (APSR) Project, a collaboration of the National Library of Australia, the Australian National University, the University of Sydney and the University of Queensland. In 2006 a draft profile for exchange of digital objects between repositories was developed as part of the APSR/PRESTA Project. This new version of the profile is based on and refines this work. More information about this project may be found on the APSR wiki.
