Extracting wrong title in PDF metadata #364

Open TeriForey opened 4 years ago

Noticed that some PDFs have a second title within the metadata, for example:

Title:          SEAJPH-April 13.indb
Creator:        Adobe InDesign CS3 (5.0)
Producer:       Adobe PDF Library 8.0

PDF version:    1.3
PDF subtype:    PDF/X-3:2002
    Title:         ISO 15930 - Electronic document file format for prepress digital data exchange (PDF/X)
    Abbreviation:  PDF/X-3:2002
    Subtitle:      Part 3: Complete exchange suitable for colour-managed workflows (PDF/X-3)
    Standard:      ISO 15930-3

The latter one, which just describes that it's a PDF, is getting returned instead of the first.

I don't think we'll deal with this at the moment, this code may actually get strippped out as the majority of titles we seem to be getting pretty consistently from the source page on the target site, if that's the case that was the predominant reason for getting this information from the PDF metadata, marking as wontfix while we evaluate if any of the rest of this information would be useful.
