In amongst the release of PDF/UA-2 (PDF for Universal Accessibility) and 
the new Well-Tagged PDF (WTPDF) standard last month, some PDF 
professionals may have missed two other new resources that may help 
explain and view them:

1. Questions and Answers about Tagged PDF from PDF association

2. Acrobat Custom File Info Panels by Peter Wyatt


Last month saw the release of PDF/UA-2 and the new Well-Tagged PDF 
(WTPDF) standard - neither of which revokes PDF/UA-1. And none of those 
are the same as PDF 1.7 vs 2.0. To many, the landscape of PDF specs may 
now seem littered with confusing acronyms and versions!

For some help disentangling it all, the PDF association has a Questions 
and Answers about Tagged PDF:

In related news, Peter Wyatt released Acrobat Custom File Info Panels. 
This is a free extension for Acrobat that adds new panels to the XMP 
metadata shown when you view File > Properties in Acrobat Pro.

The new panels allow you to view the additional conformance claims and 
dated revisions of ISO standards that can now be included in PDFs, but 
that aren't currently visible in the standard Acrobat panels.

One thing I realized in reading through the new standards and looking at 
various sample files this week is that I should probably spend some time 
learning LaTeX! Both LaTeX and LibreOffice are already capable of 
producing PDF/UA-2 files, and with some tweaking, LaTeX can produce what 
appear to be really good WTPDF files. Kudos to both those development teams!

other resources relate to:
