使用MPEG-21数字项目声明表示数字资产
Representing Digital Assets using MPEG-21 Digital Item Declaration
摘要：
在过去的几年里，出现了各种基于XML的方法来表示复合数字资产。与数字图书馆社区特别相关的方法包括元数据编码和传输标准（METS）、IMS内容打包XML绑定和CCSDS第2小组开发的XML封装数据单元（XFDU）。MPEG-21 Digital Item Declaration（MPEG-21 DID）是另一个指定XML中数字资产表示的标准，到目前为止，它在数字图书馆社区中很少受到关注。本文简要介绍了MPEG-21的标准化工作，强调了MPEG-21 DID抽象模型的主要特征，并描述了MPEG-21数字项声明语言（MPEG-21 DIDL），这是一种基于MPEG-21 DID抽象模型的数字资产表示的XML语法。此外，它简要地展示了潜在的相关性的MPEG-21 DID的数字图书馆社区描述其使用的aDORe存储库环境中的洛斯阿拉莫斯国家实验室（LANL）的研究图书馆的数字资产的表示。
英文摘要：
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.
