make metadata in .pdf files

purwoko

when we add files to Zotero, Zotero automatically grabs metadata and save it in Zotero database.
My question is how to add (makes) this metadata in .pdf file?

You can't currently do this with Zotero. Your PDF viewer or operating system may allow you to manually add this manually.

The request for this feature has been made in the past, though I'm not sure of the prospects for having it implemented in the future. I don't know if that functionality exists in Mozilla's PDF API. The poppler/xpdf programs that used to ship with Zotero couldn't do it. Other programs use PoDoFo, I believe...but relying on more third-party standa-alone apps to run in the background seems to be less than ideal.

Thanks Noksagt

Yes, i mean also with the others program (not zotero).
Ok, i will try it with PoDoFo
