Abstract: | Various XML-based approaches aimed at representing compound digital assets have emerged over the last several years. Approaches
that are of specific relevance to the digital library community include the Metadata Encoding and Transmission Standard (METS),
the IMS Content Packaging XML Binding, and the XML Formatted Data Units (XFDU) developed by CCSDS Panel 2. The MPEG-21 Digital
Item Declaration (MPEG-21 DID) is another standard specifying the representation of digital assets in XML that, so far, has
received little attention in the digital library community. This article gives a brief insight into the MPEG-21 standardization
effort, highlights the major characteristics of the MPEG-21 DID Abstract Model, and describes the MPEG-21 Digital Item Declaration
Language (MPEG-21 DIDL), an XML syntax for the representation of digital assets based on the MPEG-21 DID Abstract Model. Also,
it briefly demonstrates the potential relevance of MPEG-21 DID to the digital library community by describing its use in the
aDORe repository environment at the Research Library of the Los Alamos National Laboratory (LANL) for the representation of
digital assets. |
