前言¶
Foreword
2007年1月29日，Adobe Systems Incorporated 宣布打算将完整的便携式文档格式（PDF）1.7规范发布给美国国家标准协会（ANSI）和企业内容管理协会（AIIM），目的是通过国际标准化组织（ISO）进行出版。
自Adobe于1993年发布完整的PDF规范以来，PDF已成为更安全、更可靠的信息交换事实上的全球标准。政府和私营行业都依赖PDF来安全、可靠地共享、管理和在某些情况下保存电子记录，以供后代使用。自1995年以来，Adobe参与了各种工作组，这些工作组为ISO出版技术开发技术规范，并在ISO流程内工作，为特定行业和功能提供PDF的专业子集作为标准。今天，PDF归档（PDF/A）和PDF交换（PDF/X）是ISO标准，PDF工程（PDF/E）和PDF通用访问（PDF/UA）是提议的标准。此外，PDF医疗（PDF/H）是AIIM提出的实践指南。AIIM担任PDF/A、PDF/E、PDF/UA和PDF/H的管理员。
2008年春季，Adobe Systems Incorporated 根据PDF参考（第六版，Adobe便携式文档格式版本1.7，2006年11月）准备了ISO 32000文档，并由ISO/TC 171技术委员会、文件管理应用、SC 2小组、应用问题，在ISO成员机构批准的同时，通过特别的“快速通道程序”进行了审查、编辑和采纳。
2008年1月，这个ISO技术委员会批准了PDF 1.7的最终修订文档作为国际标准ISO 32000-1。2008年7月，ISO文档在ISO网站上出售（http://www.iso.org）。
你现在正在阅读的这份文件是ISO 32000-1标准的副本。根据与ISO的协议，Adobe Systems 被允许在其网站上以免费的PDF文件形式提供这个版本的ISO标准。这不是一个官方的ISO文件，但技术内容是相同的，包括章节编号和页码编号。
On January 29, 2007, Adobe Systems Incorporated announced it’s intention to release the full Portable Document Format (PDF) 1.7 specification to the American National Standard Institute (ANSI) and the Enterprise Content Management Association (AIIM), for the purpose of publication by the International Organization for Standardization (ISO).
PDF has become a de facto global standard for more secure and dependable information exchange since Adobe published the complete PDF specification in 1993. Both government and private industry have come to rely on PDF for the volumes of electronic records that need to be more securely and reliably shared, managed, and in some cases preserved for generations. Since 1995 Adobe has participated in various working groups that develop technical specifications for publication by ISO and worked within the ISO process to deliver specialized subsets of PDF as standards for specific industries and functions. Today, PDF for Archive (PDF/A) and PDF for Exchange (PDF/X) are ISO standards, and PDF for Engineering (PDF/E) and PDF for Universal Access (PDF/UA) are proposed standards. Additionally, PDF for Healthcare (PDF/H) is an AIIM proposed Best Practice Guide. AIIM serves as the administrator for PDF/A, PDF/E, PDF/UA and PDF/H.
In the spring of 2008 the ISO 32000 document was prepared by Adobe Systems Incorporated (based upon PDF Reference, sixth edition, Adobe Portable Document Format version 1.7, November 2006) and was reviewed, edited and adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 171, Document management application, Subcommittee SC 2, Application issues, in parallel with its approval by the ISO member bodies.
In January 2008, this ISO technical committee approved the final revised documentation for PDF 1.7 as the international standard ISO 32000-1. In July 2008 the ISO document was placed for sale on the ISO web site (http://www.iso.org).
This document you are now reading is a copy of the ISO 32000-1 standard. By agreement with ISO, Adobe Systems is allowed to offer this version of the ISO standard as a free PDF file on it’s web site. It is not an official ISO document but the technical content is identical including the section numbering and page numbering.
