Manual sync of PDF meta data

[koppor]

PDF meta data can be:

• BibEntry contains "the definitive" meta data (at the end)
• .pdf contains other meta data
  • XMP fields (Ctrl+D in PDF)
    • handled by JabRef: https://docs.jabref.org/advanced/xmp
  • embedded .bib file
    • done by authorarchive package (https://github.com/adbrucker/authorarchive)
  • first page contains "doi:" --> use DOI data
  • text parsing of the first page of the PDF (org.jabref.logic.importer.fileformat.PdfContentImporter)
  • text parsing of the complete PDF (Grobid)
    • Use GROBID for extraction of metadata from PDFs JabRef/jabref#6158
• doi contains other meta data

Implement a n merge dialog where each column is one source of information. User selects column which data they wants.

• First shot: new columns to merge entries dialog
• Advanced shot: Improve entry merge dialog (3-way merge) JabRef/jabref#6190
