Exporting from orgmode to LaTeX needs a high level approach: don't do complicated things, just use the appropriate LaTeX API. Unfortunately adding XMP metadata is the largest construction site in the LaTeX world: https://tug.org/TUGboat/tb43-3/tb135fischer-xmp.pdf The LaTeX Project Team developed a new pdf management, see here: https:// ctan.org/pkg/pdfmanagement-testphase : "The new PDF management code offers backend-independent interfaces to central PDF dictionaries, tools to create annotations, form Xobjects, to embed files, and to handle PDF standards." The most important command is `\DocumentMetadata{}` and it needs to be placed before `\ḑocumentclass{}` The idea to have a LATEX_PRE_HEADER to insert `\DocumentMetadata{}` is exactly what you need right now, if you export from orgmode to current LaTeX. With `\DocumentMetadata{}` you can add most of the necessary xmp data -- and I write most, because I'm using it on a daily basis, but haven't checked if really everything is included yet. -- Regards, Alexander
