The budding standard, targeted toward software developers, identifies elements in the PDF standard relevant to accessibility, specifies valid implementation of such elements in conforming files, and specifies requirements for conforming PDF readers and for conforming Assistive Technology (AT).
Doug Miles, Director of AIIM Market Intelligence, recently posted that PDF/A adoption was making slow but steady progress after he did an small, informal survey of 144 people. Miles asked, “Do you store a significant proportion of your records in any of the following formats (native (eg. .doc, .xls), .pdf, HTML, .tiff, .jpeg, .pdf/a)?” He found that 30 percent of respondents are now using PDF/A, which still lags significantly behind the other specified formats. But that may not be the case much longer.
