Organizations listed in italics are not members of the PDF Association but are included in this listing because they are either assistive-technology providers or developers of free open source software, with products that offer at least partial support for tagged PDF and PDF/UA.
The ability to create tagged PDF documents with semantically-appropriate structure elements from a source file or existing untagged PDF.
The ability to create PDF documents conforming to PDF/UA (ISO 14289-1:2014).
The ability to correct the logical structure tree of a tagged PDF file.
The ability to confirm PDF/UA conformance based on the Matterhorn Protocol's set of checks:
|P||Partial, some limited aspects of verification|
|M||All machine checks. Without human verification, machine verification is usually inadequate.|
|Complete validation, all checks (machine and human).|
The product includes an end-user-oriented interactive PDF (or PDF-alternative) viewer that uses tagged PDF to make PDF/UA files available to Assistive Technology.
