VeraPDF parse status as a proxy for PDF rendering: experiments with the Synthetic PDF Testset
29 June 2023
Last month I wrote this post, which addresses the use of JHOVE and VeraPDF for identifying preservation risks in PDF files. In the concluding section I suggested that VeraPDF’s parse status might be used as a rough “validity proxy” to identify malformed PDFs. But does VeraPDF’s parse status actually have any predictive value for rendering? And how does this compare to what JHOVE tells us? This post is a first attempt at answering these questions, using data from the Synthetic PDF Testset for File Format Validation by Lindlar, Tunnat and Wilson.
