What the flattened curbside or stepless access is for wheelchair users, the barrier-free PDF in accordance with the PDF/UA standard is for reading and editing documents and forms. Without limiting the diversity of PDF technology, it determines how unrestricted accessibility of content in PDF files is ensured.
The constantly growing demands on formats were no longer able to meet the constantly growing requirements for reliable long-term digital storage of important documents. In addition, there was a desire for a searchable, compact format that was robust and widely usable across platforms. In 2005, an ISO standard based on the PDF format started to write a new chapter in the history of digital archiving of documents: PDF/A. In this blog post, I am writing about how system-independent archiving of project files with PDF/A-3 can be achieved and how the advantages of PDF/A-3 are presented in the form of application scenarios and the different points of view regarding PDF/A-3.
