ISO 32000 specifies a digital form for representing electronic documents to enable users to exchange and view electronic documents independent of the environment in which they were created or the environment in which they are viewed or printed. Document available as of: 2008-07-01 from ISO.

The Adobe Supplement to ISO 32000, BaseVersion 1.7, ExtensionLevel 3 describes Adobe's extensions and implementation notes for Adobe Acrobat 9.0 and LiveCycle ES 8.2. It also includes extensions and implementation notes for BaseVersion 1.7, ExtensionLevel 1 and 2. It is Adobe's intent to submit these extensions to ISO for inclusion in the next revision to ISO 32000.

The PDF Reference, Sixth Edition, is available as a PDF portfolio from Adobe but has been superceded by the ISO 32000-1 document. Both documents provide a description of the PDF file format and are intended primarily for developers of PDF producer applications that create PDF files directly. These documents also contain enough information to allow developers to write PDF consumer applications that read existing PDF files and interpret or modify their contents.

On behalf of the International Organization for Standardization (ISO) and in support of ISO 32000 Adobe Systems Incorporated maintains a name, handler and function/extension registry freely open to all PDF developers following the specifications given in Annex E of ISO 32000-1. To avoid conflicts with other PDF names, handlers, extensions and with future versions of PDF, complete and submit this form to register the ones you want to reserve.

Adobe has submitted these extensions to the United States ISO Committee for inclusion in the next revision to
ISO 32000.
