Mamy thanks for your reply, Hans.
I think this might be simpler for me:
\starttext
\startluacode
function document.transfer_metadata(name)
local main_doc = lpdf.epdf.load(name)
lpdf.addtocatalog("Lang", lpdf.string(main_doc.Catalog.Lang))
lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title))
lpdf.addtoinfo("Subject", lpdf.unicode(main_doc.Info.Subject))
lpdf.addtoinfo("Author", lpdf.unicode(main_doc.Info.Author))
lpdf.epdf.unload(name)
end
\stopluacode
\unexpanded\def\TransferMetadata#1%
{\ctxlua{document.transfer_metadata("#1")}}
\null
\TransferMetadata{name.pdf}
\stoptext

Many thanks for your help,
Pablo
