范围 本文档定义了XMP元数据的两个基本组件:--数据模型:数据模型是最基本的方面。这是一个抽象模型，定义了 XMP元数据项的形式，本质上是XMP可以生成的语句结构 资源。 --序列化:XMP的序列化定义了XMP数据模型的任何实例可以如何 记录为XML。 此外，本文档还定义了一组核心属性，这些属性是XMP元数据项，可以应用于各种文件格式和使用领域。 在特定的文件格式和域中嵌入XMP数据包- 特定的XMP属性超出了本文档的范围。交叉引用:IETF RFC 3066IETF RFC 3986IEEE 754IETF RFC 4122IETF RFC 2046ISO 639-1ISO 3166-1ISO 639-2购买本文件时可获得的所有现行修订均包含在购买本文件中。

Scope This document defines two essential components of XMP metadata:-- Data model: The data model is the most fundamental aspect. This is an abstract model that defines the forms of XMP metadata items, essentially the structure of statements that XMP can make about resources. -- Serialization: The serialization of XMP defines how any instance of the XMP data model can be recorded as XML. In addition, this document defines a collection of core properties, which are XMP metadata items that can be applied across a broad range of file formats and domains of usage. The embedding of XMP packets in specific file formats and domain-specific XMP properties are beyond the scope of this document.Cross References:IETF RFC 3066IETF RFC 3986IEEE 754IETF RFC 4122IETF RFC 2046ISO 639-1ISO 3166-1ISO 639-2All current amendments available at time of purchase are included with the purchase of this document.
