Dear list, I have the following sample to import metadata (title, author, subject, keywords and dates). \starttext \startluacode function document.transfer_metadata(name) local main_doc = lpdf.epdf.load(name) lpdf.addtocatalog("Lang", lpdf.unicode(main_doc.Catalog.Lang), main_doc.Catalog.Lang) lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title), lpdf.string(main_doc.Info.Title)) lpdf.addtoinfo("Subject", lpdf.unicode(main_doc.Info.Subject), lpdf.string(main_doc.Info.Subject)) lpdf.addtoinfo("Keywords", lpdf.unicode(main_doc.Info.Keywords), lpdf.string(main_doc.Info.Keywords)) lpdf.addtoinfo("Author", lpdf.unicode(main_doc.Info.Author), lpdf.string(main_doc.Info.Author)) 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 Importing from https://pdf.ousia.tk/metadata.pdf gives https://pdf.ousia.tk/imported-metadata.pdf. Imported metadata from title, creation and modification dates are not displayed right in Acrobat. Other PDF viewers display these metadata fine. How can I get that Acrobat displays the metadata from the imported document? Many thanks for your help, Pablo -- http://www.ousia.tk
