. 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.

Queries of Digital Content Descriptions in MPEG-7 and MPEG-21 XML documents
. They have posed an interesting challenge to XML query language design.. The paper shows certain critical query specification issues for MPEG-7 and MPEG-21 XML documents and illustrates a logic method to handle the limitations in current text-oriented XML query languages for retrieving multimedia content and digital items.. MPEG-7 and MPEG-21 standards have posed an interesting challenge to XML query language design in covering different XML aspects.. In addition, a logic formalism called Path Predicate Calculus is illustrated to handle the limitations in current text-oriented XML query languages for multimedia XML queries.. We depicts the proposed query language MMDOC-QL and its embedded path predicate calculus.. The language is used to illustrate how to specify multimedia objects as temporal/audio/visual datatypes for content and digital item retrievals.. Section discusses related work in multimedia document and query languages.. MPEG-7 and MPEG-21 XML Documents MPEG committee has decided to adopt XML Schema Language for describing multimedia content in MPEG-7 and for specifying digital item declarations in MPEG-21.
A Framework of Guidance for Building Good Digital Collections - National Information Standards Organization (NISO)
. Look for particularly problematic items, such as color variations, display of non-English language characters, and rendition of XML.. Rights Expression Languages (RELs) are seen by some as a solution and their continued development and application bear watching.. (Karen Coyle, 2004) analyzes a sample of rights expression languages in terms of their impact on the selection, maintenance, and preservation of digital content.
