标准范围

ISO/IEC 21000-4:20 06规定了如何在数字项目中包含知识产权管理和保护（IPMP）信息和受保护部件。它提供了一种简单的机制来将受保护的部分包括在数字项目的DID（ISO/IEC 21000-2）描述中，并提供了用于描述受保护内容的治理和工具的机制。ISO/IEC 21000（MPEG-21）定义了多媒体传递和消费的开放框架，内容创建者和内容消费者都是焦点。MPEG-21的愿景是定义一个多媒体框架，以实现跨不同社区使用的广泛网络和设备透明和增强地使用多媒体资源。MPEG-21中的基本架构概念是数字项。数字项目是结构化的数字对象，包括标准表示和标识以及元数据。它们是MPEG-21框架中的基本事务单元。在ISO/IEC 21000-4:20 06中，该技术在三个主要部分中进行了描述:IPMP DIDL:ISO/IEC 21000-4:20 06为需要通过IPMP治理进行保护的部分数字项目提供了替代规范表示。这种表示被称为IPMP数字项目声明语言(IPMP DIDL)，并定义了与DID模型(ISO/IEC 21000-2)中的实体相对应的受管理XML元素。IPMP信息描述符:IPMPInfoDescriptor及其相关联的元素用于传达关于IPMP治理和数字项目或其部分所需的工具的信息。IPMP一般信息描述符:IPMPGeneralInfoDescriptor及其相关联的元素用于传达与完整数字项目相关的一般信息。ISO/IEC 21000-4:20 06的目的是允许在数字项目的整个生命周期中控制其流动和使用。ISO/IEC 21000-4:20 06故意没有指定保护措施、密钥、密钥管理、信任管理、加密算法、认证基础设施或作为完整IPMP解决方案的一部分也需要的其他组件。

ISO/IEC 21000-4:2006 specifies how to include Intellectual Property Management and Protection (IPMP) information and protected parts in a Digital Item. It provides a simple mechanism to include protected parts in the DID (ISO/IEC 21000-2) description of a digital item, and provides mechanisms for describing the governance over, and the tools used for the protected content.

ISO/IEC 21000 (MPEG-21) defines an open framework for multimedia delivery and consumption, with both the content creator and content consumer as focal points. The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities. The basic architectural concept in MPEG-21 is the Digital Item. Digital Items are structured digital objects, including a standard representation and identification, and metadata. They are the basic unit of transaction in the MPEG-21 framework.

Within ISO/IEC 21000-4:2006 this technology is described in three main sections:

• IPMP DIDL: ISO/IEC 21000-4:2006 provides an alternative normative representation for parts of Digital Items that require protection through IPMP governance. This representation is termed the IPMP Digital Item Declaration Language (IPMP DIDL), and defines governed XML elements corresponding to entities in the DID model (ISO/IEC 21000-2).
• IPMP Info Descriptor: The IPMPInfoDescriptor and its associated elements are used to communicate information about the IPMP governance and tools required for a Digital Item or its parts.
• IPMP General Info Descriptor: The IPMPGeneralInfoDescriptor and its associated elements are used to communicate general information relating to a complete Digital Item.
