标准摘要
[中文适用范围]: 本文件规定了以下内容: — 如何唯一标识数字项目(及其组成部分); — 如何唯一标识与数字项目(及其组成部分)相关的知识产权,例如抽象概念; — 如何表达上述两个标识符之间的关系; — 如何处理数字项目标识符在功能粒度上的差异; — 如何唯一标识描述方案; — 数字项目(及其组成部分)与现有标识系统之间的关系。附件C列出了相关标识系统。该清单并非详尽无遗,且可能随时间而变化; — 如何表达两个数字项目之间的关系。 本文件不涉及以下内容: — 对于已有标识和描述方案并正在使用的数字内容元素,不规定新的标识系统(例如,本文件不试图替代ISO 3901中定义的ISRC用于声音记录); — 对数字内容进行规范性描述的方案。 [外文原描述]: This document specifies: — How to uniquely identify Digital Items (and parts thereof); — How to uniquely identify IP related to the Digital Items (and parts thereof), for example abstractions; — How to express the relationship between the two above identifiers; — How to deal with varying levels of functional granularity for Digital Item identifiers; — How to uniquely identify description schemes; — The relationship between Digital Items (and parts thereof) and existing identification systems. Annex C contains a list of relevant identification systems. This is not an exhaustive list and is subject to change over time; — How to express the relationship between two Digital Items. This document does not specify: — New identification systems for the content elements for which identification and description schemes already exist and are in use (e.g. this document does not attempt to replace the ISRC, as defined in ISO 3901, for sound recordings); — Normative description schemes for describing content.
