Adobe's Portable Document Format (PDF) is now accessible as an ISO International Standard - ISO 32000-1.

This move follows a decision by Adobe Systems Incorporated, original developer and copyright owner of the format, to relinquish control to ISO, who is now in charge of publishing the specifications for the current version (1.7) and for updating and developing future versions.

The new standard, ISO 32000-1, Document management ? Portable document format ? Part 1: PDF 1.7, is based on the PDF version 1.7 developed by Adobe. This International Standard supplies the essential information needed by developers of software that create PDF files (conforming writers), software that reads existing PDF files and interprets their contents for display and interaction (conforming readers), and PDF products that read and/or write PDF files for a variety of other purposes (conforming products).

Future versions of the format will be published as subsequent parts of the standard by the ISO subcommittee in charge of its maintenance and development (SC 2, Application issues, of ISO technical committee ISO/TC 171, Document management applications).

ISO 32000-1, Document management ? Portable document format ? Part 1: PDF 1.7 costs 370 Swiss francs.
