 Adobe的PDF 1.7版在2008年成为ISO32000标准。此后, ISO/TC 171/SC 2/WG 8成员,负责规范标准的工作组,一直不断地完善这一规范。最近新发布的版本定为PDF2.0。












ISO 32000- 2,文件管理-便携式文档格式-第2部分:PDF 2.0,是第一个完全在ISO指导方针和过程要求规范内中开发的PDF规范。它更清晰、更整洁、支持非专利技术,并为软件供应商提供了一个公平的竞争环境,这些软件供应商可以创建、显示、编辑或以其他方式处理PDF电子文档。除了保持PDF的核心价值之外,PDF 2.0还为新的用例、功能和工作流提供了坚实的基础。

ISO 32000-2 标准是由ISO/TC 171技术委员会制定的,有关文件管理应用,SC 2专门小组,文档文件样式,电子文档管理系统(EDMS)和管理信息真实性的标准。ISO/TC 171技术委员会的秘书处是由美国国家标准学会(以下简称,ANSI)担任的,ANSI也是美国在ISO的成员组织。



The worldwide standard for electronic documents is evolving

The PDF format exemplifies the value of standards. Had the specification for PDF not been published from the technology’s introduction in 1993, PDF would just be one of a dozen document formats. More than any other single factor, Adobe’s decision to make the PDF specification freely available enabled an ecosystem of developers.

Adobe’s PDF version 1.7 became ISO 32000 in 2008. Since then, members of ISO/TC 171/SC 2/WG 8, the working group responsible for the standard, have continued the development of the specification, with the just-published version defined as PDF 2.0.


PDF’s value proposition – the reason why PDF is today’s worldwide de facto standard for electronic documents – is the fact of standardization itself. PDF files are supposed to be entirely self-contained and interoperable, working equally well with PDF software from every vendor. End-users should be able to gain equivalent results irrespective of their choice of software. This core feature – PDF files always look and work the same way – is the dominant reason for the technology’s success.

In PDF 2.0, the fundamentals of PDF remain identical, but the value to users has increased. Perhaps the most important enhancement is also the most subtle. PDF 2.0 addresses ambiguities, corrects errors, modernizes many features, updates normative references and six critical clauses, totalling 14 % of the 972-page specification that were entirely rewritten.

Although these changes aren’t new features, they make it easier to understand and successfully implement the specification, with better interoperability. In short, PDF 2.0 will make it easier and less costly for developers to improve their support for PDF at every level.

PDF 2.0 does, however, include many entirely new features in addition to the improvements to the existing specification:

Unencrypted wrapper documents allow secured PDF files to be delivered inside a readable “cover letter” document.

There’s new support for rich media annotations, geospatial features and PRC, a 3D format.

Associated files, first introduced with PDF/A-3, now extend to any PDF 2.0 document the ability to include machine-readable metadata about files attached to the PDF.

Users gain from an enhanced ability to include source, data and other file formats as part of their PDF document.

Clause 14.8 on tagged PDF has been completely overhauled with a revised tag set, support for namespaces, MathML support and pronunciation hints. The result will be more accessible documents that are also much easier to repurpose for text extraction, conversion to HTML for small devices, and more.

Digital signature features have been updated to meet the latest specifications, allowing users new options for verifying digitally signed PDF documents.

PDF now supports 256-bit AES encryption, a current-generation standard.

ISO 32000-2, Document management – Portable document format – Part 2: PDF 2.0, is the first PDF specification developed entirely within the ISO guidelines and process. It’s clearer, cleaner, supports non-proprietary technologies and ensures a level playing field for software vendors that create, display, edit or otherwise process PDF electronic documents. In addition to staying true to PDF’s core value, PDF 2.0 provides a solid foundation for new use-cases, capabilities and workflows.

ISO 32000-2 was developed by technical committee ISO/TC 171, Document management applications, subcommittee SC 2, Document file formats, EDMS systems and authenticity of information, whose secretariat is held by ANSI, the ISO member for the United States.
