ISO 32000-2:2020, the latest edition of the PDF specification first published in 1993, is now available from ISO.org.
Several subset ISO standardized specifications based on the 2020 edition of ISO 32000-2, including ISO 19005-4 (PDF/A-4), ISO 15930-9 (PDF/X-6), ISO 16612-3 (PDF VT-3) and ISO 23504 (PDF/R-1), are already released. ISO 14289-2 (PDF/UA-2) remains under development, with publication expected in 2022. A number of other extensions and other improvements, especially in the areas of cryptography, reuse and forms, are in the pipeline.
PDF 2.0 was first published in July, 2017 the first PDF specification developed entirely within the ISO working-group structure. ISO 32000-2:2020 is the second edition of that document; a so-called "dated revision".
The 2020 edition of PDF 2.0 includes a number of critical updates to normative references as well as other corrections and clarifications. The new document replaces the 2017 edition, and continues the refinement of the PDF format originally published by Adobe Systems in 1993.
Subject-matter experts who are either members of the PDF Association (an ISO Category A Liaison organization) or whose country is a member of ISO's TC 171 SC 2 can join the other experts in Working Group 8 in accessing the committee's draft documents and submitting comments towards the next edition.
The PDF Association maintains an archive of documents, many originally published by Adobe Systems, that are used by ISO 32000-2:2020 as normative references (i.e., necessary to implementation). Many of these documents are freely downloadable. A current list of PDF-related work in ISO committees is maintained here.
The PDF Association is the meeting-place of the PDF industry. The staff of the PDF Association are dedicated to delivering the information, services and value the members have come to expect. Staff members of the PDF Association include: Duff Johnson (Chief Executive Officer) Thomas Zellmann (PDF Evangelist) Matthias Wagner (Operations Director) Alexandra Oettler (Editor) Nicole Gauger (Editor)
