PDF文件中符合此文档的文档部分元数据可用于通信 印刷品及其组件的预期外观。预期用途示例如下: 在生产过程中进行直接口译、创建工作通知单（如XJDF）或填充 管理信息系统中的记录。本文件建立在ISO 16612-2（PDF/VT）和 ISO 32000-2（PDF 2.0），用于对与中的页面或页面组相关的元数据进行编码 PDF文件。 注:本文档中提供的文档部分元数据适用于单个文档部分，而 XMP元数据通常适用于整个文档的范围。XMP可以应用于单个页面或页面的一部分，但这种用法非常少见。因此，XMP不适用于多个收件人或绑定信息等页面集需要元数据的情况。例如，XMP在PDF/X中用于文件一致性标识，也用于其他文件级信息，如作者。 本文件定义了标准化元数据:-提供产品意图规范，如纸张介质选择和装订信息； -确定内容页拟代表的产品类型（例如宣传册、信函） （或明信片）；-确定用于可变文档打印的每个内容页的预期收件人 应用。 本文档定义了一个基本一致性级别，其中包括元数据框架的语法 以及一组核心元数据的语义。交叉引用:ISO 32000-1:2008 ISO 12647-2:2013ISO 3166-1ISO 16612-2ISO 32000-2购买本文件时，所有当前可用的修订版均包含在购买本文件中。

The document part metadata in a PDF file that conforms to this document can be used to communicate the intended appearance of print products and their components. Examples of intended use are: direct interpretation within a production process, creation of job tickets such as XJDF, or populating records in an MIS. This document builds on the DPart syntax as specified in ISO 16612-2 (PDF/VT) and ISO 32000-2 (PDF 2.0) which is designed for encoding metadata related to pages or groups of pages in PDF files. NOTE The document part metadata provided in this document applies to individual document parts, whereas XMP metadata typically applies to the scope of the entire document. XMP can apply to the scope of an individual page or part of a page but this usage is very uncommon. Thus, XMP is not applicable for the case where metadata is required for sets of pages such as multiple recipients or binding information. For example, XMP is used within PDF/X for file conformance identification and is also used for additional file level information such as author. This document defines standardized metadata to:— provide product intent specifications such as paper media selection and binding information;— identify the type of product that the content pages are intended to represent (e.g. a brochure, letter or postcard);— identify the intended recipient of each of the content pages for variable document printing applications. This document defines a base conformance level that includes the syntax of the metadata framework and the semantics of a core set of metadata.Cross References:ISO 32000-1:2008ISO 12647-2:2013ISO 3166-1ISO 16612-2ISO 32000-2All current amendments available at time of purchase are included with the purchase of this document.
