---------- Forwarded message ---------- From: Andrew Kirkpatrick <akirkpat@adobe.com> Date: Thu, Apr 14, 2011 at 12:41 PM Subject: RE: PDF Technology Notes To: Loretta Guarino Reid <lorettaguarino@google.com> That's some of the best parts! :) I'd say that we could do: (yellow is added, strikeouts are strikeouts) Introduction The Portable Document Format (PDF) is a file format for representing documents in a manner independent of the application software, hardware, and operating system used to create them, as well as of the output device on which they are to be displayed or printed. PDF files specify the appearance of pages in a document in a reliable, device-independent manner. The PDF specification was introduced by Adobe Systems in 1993. The origins of PDF and the Adobe® Acrobat® product family date to early 1990. At that time, the PostScript® page description language was a standard for the production of the printed page. PDF builds on the PostScript page description language by layering a document structure and interactive navigation features on PostScript’s underlying imaging model, providing a convenient, efficient mechanism for enabling documents to be reliably viewed and printed anywhere. PDF is an International Standard PDF is an International Standard: PDF 1.7 (ISO 32000-1). On January 29, 2007, Adobe Systems Incorporated announced its 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). In January 2008, this ISO technical committee approved the final revised documentation for PDF 1.7 as an international standard. The PDF specification was first published at the same time the first Acrobat products were introduced in 1993. As the format evolved, specialized subsets of the full PDF specification were developed to meet specific technical requirements. These subsets became standards published by the International Organization for Standards (ISO) or are in the process of standardization. Of note for accessibility is PDF/UA. PDF/UA (Universal Accessibility) became an ISO Draft International Standard (DIS) in November 2010 (ISO/DIS 14289-1). (See PDF/UA Wiki (ISO DIS 14289 - 1).) The scope of PDF/UA is not meant to be a techniques (how-to) specification, but rather a set of guidelines for creating accessible PDF. The specification describes the required and prohibited components and the conditions governing their inclusion in or exclusion from a PDF file in order for the file to be available to the widest possible audience, including those with disabilities. The mechanisms for including the components in the PDF stream are left to the discretion of the individual developer, PDF generator, or PDF viewing agent. PDF/UA also specifies the rules governing the behavior for a conforming reader. Do you think that helps?

I don't know whether you can fix them or whether this is something that Michael needs to fix. >
