Automatically populating metadata for PDF files based on filename

Bhuvanesh · 01-14-2019, 02:42 PM

Hi, I have lots of PDF files with messed up metadata, but their filenames all follow one of these forms:
Authors (separated by commas) - Title.pdf
Authors (separated by commas) - Series SeriesNumber - Title.pdf

Is there a way to use this filename information to correct the metadata?

Thanks,
Bhuvanesh

Thanks! Will that metadata be saved to the PDF file, so that the corrected metadata appears when I transfer the PDF to my phone, or is it internal to calibre?

No it wont, it will go into calibre's data base.

However, you can inject it into the library copy of the PDF using the Embed Metadata tool, which you'll probably need to add to a toolbar or menu via Preferences->Toolbars and menus. Metadata can also be embedded in the copy that's created when the Send to a Device and Save to Disk tools are used.

Caveat: I'm not a 100% certain metadata embedding (in Library, or Save, or Send) will work on all PDFs. And most PDF reading apps won't display metadata apart from Title and Author, e.g. Series because its not a Dublin Core element, and nor anything else that's embedded as XMP metadata.

I found this nice regex for extracting metadata from the filename:

Is there an easy way to replace " ~" in the filename with ":" (without quotes) in the title in the metadata?
