Why PDF/A validation matters, even if you don't have PDF/A
07 July 2015
This is the first instalment of a 2-part blog. It was prompted by the upcoming Digital Preservation Coalition briefing When is a PDF not a PDF?, for which I was asked to prepare a presentation. My initial idea was to give an overview of the work we did on PDF preservation risk assessment using a PDF/A validator in the SCAPE project. Most of this has already been covered by a series of earlier blog posts. Those blogs very much represent different stages of a work in progress, and I think this makes them somewhat challenging for readers who are new to the subject.
