If it's a paper with a DOI, it's easy to re-generate the metadata. Same for an ISBN. My guess is that this type of file won't hash well, because the metadata and the data (cover page) are mutable. Zotero tries to extract metadata from PDF files, but it doesn't always succeed. I use Zotero with the ZotFile and BetterBibTex plugins for my academic papers, and Calibre for my ebooks. I'm not an archivist, and I don't read enough to benefit from automating this problem. https://xkcd.com/1319/ https://xkcd.com/1319/
