Dear list,

I have the following sample:

  \starttext
  \startluacode
  function document.transfer_metadata(name)
    local main_doc = lpdf.epdf.load(name)
    lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title),
      lpdf.string(main_doc.Info.Title))
    lpdf.addtoinfo("CreationDate",
      lpdf.string(main_doc.Info.CreationDate))
    lpdf.addtoinfo("ModDate", lpdf.string(main_doc.Info.ModDate),
      main_doc.Info.ModDate)
    lpdf.epdf.unload(name)
  end
  \stopluacode
  \unexpanded\def\TransferMetadata#1%
    {\ctxlua{document.transfer_metadata("#1")}}
  \startTEXpage[offset=1em, align=center]
  \ssbf metadatos\\importados
  \TransferMetadata{metadata.pdf}
  \stopTEXpage
  \stoptext

Being the sample file https://pdf.ousia.tk/metadata.pdf, Acrobat cannot
display the imported title or either the creation or modification dates.

What am I missing to make Acrobat display the imported metadata?

Many thanks for your help,

Pablo

timing, so best use the official methods:

   function document.transfer_metadata(name)
     local main_doc = lpdf.epdf.load(name)
     context.setupinteraction { title = main_doc.Info.Title }
     lpdf.epdf.unload(name)
   end

acrobat looks at the metadata blob

Many thanks for your reply, Hans.

This works in MkIV, but not in LMTX:

 context.setupinteraction { title = main_doc.Info.Title }

BTW, is there a way to add CreationDate and ModDate?

Many thanks for your help again,

Pablo
