Representing Digital Assets for Long-Term Preservation using MPEG-21 DID

TL;DR

This paper explores the use of MPEG-21 DID for long-term digital asset preservation, analyzing its compatibility with OAIS standards and its potential advantages over existing formats.

Contribution

It provides an in-depth analysis of MPEG-21 DID's applicability to digital preservation, mapping its core components to OAIS and evaluating its XML syntax.

Findings

MPEG-21 DID can effectively represent digital assets for preservation.

Mapping to OAIS model demonstrates compatibility and potential benefits.

MPEG-21 DIDL offers a flexible XML-based syntax for digital asset encoding.

Abstract

Various efforts aimed at representing digital assets have emerged from several communities over the last years, including the Metadata Encoding and Transmission Standard (METS), the IMS Content Packaging (IMS-CP) XML Binding and the XML Formatted Data Units (XFDU). The MPEG-21 Digital Item Declaration (MPEG-21 DID) is another approach that can be used for the representation of digital assets in XML. This paper will explore the potential of the MPEG-21 DID in a Digital Preservation context, by looking at the core building blocks of the OAIS Information Model and the way in which they map to the MPEG-21 DID abstract model and the MPEG-21 DIDL XML syntax.
