Acrobat doesn’t read imported metadata
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 -- http://www.ousia.tk

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? 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 ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

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 -- http://www.ousia.tk
