Created primarily for software developers, the Matterhorn Protocol fosters PDF/UA adoption by specifying a series of tests enabling the effective exchange of information on PDF/UA conformance.
The PDF Association celebrated a particularly special birthday as part of its most recent Technical Conference: it has now been 20 years since the PDF format was first published.
What does universal accessibility actually mean when it comes to PDFs? It is the idea that everyone should be equally able to independently access and use the information contained within a PDF document.
PDF/UA in a Nutshell will show you just what PDF/UA is. This brochure provides a clear summary of the key facts, the standards requirements, the latest developments and the current legal situation regarding PDF accessibility, all in one place. In addition, it suggests potential applications for the standard and lists the tools that can be used to create and validate PDF/UA-compliant documents.
Information plays a central role in society today, and it is becoming more and more common for that information to be offered in digital form alone. The reliable, user-friendly Portable Document Format (PDF) has become the worlds file type of choice for providing information as a digital document.
Für viele Menschen, zum Beispiel mit Sehbehinderung, blieb das Dateiformat PDF lange Zeit unzugänglich, da PDF ursprünglich auf die visuelle Präsentation fokussiert war.
The PDF/UA standard defines technical requirements for universally-accessible PDF documents by identifying a set of relevant PDF functions (including text content, images, form fields, comments, bookmarks and metadata) based on ISO 32000-1 (PDF 1.7).
As a quality standard for universally accessible PDF documents aimed at both software developers and document creators, PDF/UA serves as a clear basic requirement for everyone involved in PDF creation.
In principle, universally-accessible PDF documents can either be generated directly during document creation, using a suitable program, or indirectly generated by adapting an existing PDF document.
