Packaging models for the storage and distribution of complex digital objectsin archival information systems: a review of MPEG-21 DID principles

Abstract

In recent years, the number of organizations making digital information available has increased dramatically. This evolution has encouraged the development of various approaches to represent complex digital objects. Approaches that are of specific relevance to the digital library and archiving community include the Metadata Encoding and Transmission Standard (METS), the Content Packaging XML Binding of the Instructional Management System (IMS) project, and the Sharable Content Object Reference Model (SCORM). The MPEG-21 Digital Item Declaration (MPEG-21 DID) is yet another packaging approach that, so far, has received little attention in the digital library community. The primary goal of this article is to offer a method to compare these packaging approaches in the context of the needs of the digital library community and the rising digital preservation programs. The contribution of this paper is the definition of an integrated reference framework, based on both the ISO OAIS Reference Model and a set of additional significant properties that affect the quality, usability, encoding, and behavior of complex digital objects. This article also gives a brief insight into MPEG-21 DID and examines its potential relevance by showing the results obtained from applying the proposed reference framework.

Intelligent Adaptation Model Based on MPEG-21 Framework

“…Research works on semantic analysis provides a feasible way for user to access video according to their preference on video content. In [18], a systematic study of automatic classification of digital object into a archival information system. Packaging models have been considered to achieve good performance on adaptation analysis.…”

DOLAR: virtualizing heterogeneous information spaces to support their expansion

“…The main difference here is that ontologies use inference as the primary compositional mechanism, while in DOLAR we use DVO instantiation.DVOs allow semantically diverse and heterogeneous storage artifacts to act as ‘native objects’ of the virtual information space, hiding any underlying physical/storage models. This feature also distinguishes DOLAR from object‐oriented databases 45, 46 and various XML object packaging approaches, such as METS 22, MPEG‐21 DID 47, and Digital Content Components 48.…”

User-author centered multimedia building blocks

“…In the last years, many domain specific initiatives have been concerned with sharing and reusing digital content. Since each research domain uses its own terminology to refer to the sharable and reusable entities, we will use a term borrowed from digital libraries: complex digital object (or simply digital object) [4], whose concept and model can be considered a common foundation.…”

“…In the second perspective, authors can decompose and adapt the reused production and fuse reused parts into a new production. This perspective involves the need for complex digital objects [4] to be shared. These objects can comprise many multimedia items and the relationships among them.…”
