Using METS for the preservation and dissemination of digital archives
Introduction
Alternatives to METS
METS is not the only framework for packaging disparate metadata; other XML schemas for use in the digital preservation environment have also been proposed. They include:
- The Sharable Content Object Reference Model (SCORM): a packaging model developed for use with learning objects.
- The MPEG-21 Digital Item Declaration Language (DIDL): used in commercial applications and has some proponents in the digital library community. It is an abstract model but also has an XML syntax and acts as a metadata format containing all the necessary elements for automated metadata harvesting.
- Resource Description Framework (RDF): a family of World Wide Web Consortium specifications; designed as a metadata model using XML, it has also subsequently been taken up as a general method of modeling knowledge through a variety of syntax formats.
- IMS Content Packaging Specification (IMS-CP): developed by the IMS Global Learning Consortium for defining interoperability between systems used with learning objects.
- XML Formatted Data Unit (XFDU): currently under development by the Consultative Committee for Space Data Systems (CCSD), who produced the OAIS model.
