Get your zero-cost copy of ISO 32000-2 now! Includes ISO-approved errata and new PDF 2.0 crypto extensions.
This public GitHub repository "pdf-issues" is hosted by the PDF Association and provides all developers a means of openly reporting errata against ISO PDF related standards for review and resolution by industry and ISO experts. All issues in ISO PDF related standards are important, from minor typos and formatting issues, to larger ambiguous, unclear or apparently contradictory statements. By reaching consensus on resolutions as an industry, PDF interoperability and implementation reliability will be improved.
The current set of resolved errata are presented as additions, deletions or editor notes to the published wording in the relevant ISO standard organized by clause number. GitHub Issue numbers will appear as popup tooltips when hovering over changes and refer back to closed GitHub pdf-issues.
If a small blue ISO logo is also shown , then that errata has been approved by both the PDF Association's appropriate TWG and the appropriate ISO working groups responsible for PDF.
If a small gray ISO logo is also shown , then that errata has been approved by the PDF Association's appropriate TWG and submitted to the appropriate ISO working group and is waiting for approval.
If no ISO logo is shown then the errata has been resolved by the PDF Association's PDF Technical Working Group but has not yet been submitted to ISO for ratification.
Due to ISO copyright, only minimal surrounding text from the relevant ISO standard is provided that is sufficient to understand how the resolution is being applied.
Errata in the following published ISO publications are supported:
Errata on PDF 1.7 (ISO 32000-1:2008) and withdrawn ISO publications are not supported - refer to ISO 32000-2 instead. The PDF Association maintains a full list of all PDF-related ISO publications.
Not all resolutions proposed here are officially authorized by the ISO working groups responsible for PDF and may get changed when reviewed by the ISO working group.
A full list of all ISO and industry-agreed issue resolutions (as pseudo-markup) is actively maintained at https://pdf-issues.pdfa.org/.
Errata can always be referred by the appropriate GitHub issue numbers(s). Resolutions are published to a set of static URLs at https://pdf-issues.pdfa.org/ of the form <standard-number>/clause<clause-number>.html
. Each of these resolution pages also includes anchor points for all Headings (#Hx.y.z
anchors to heading X.Y.Z in the appropriate ISO standard) and Tables (#TableXXX
anchors to Table XXX in the appropriate ISO standard). This allows very precise linkages to final resolution outcomes, without scrolling through long technical GitHub discussions.
