Hi, Pablo—

My inquiry concerns the possibility of getting custom properties that I could specify using \setupinteraction in a way that would output in the PDF file (under Document Info or Document Properties) as:

Editor (not Author)                   editors names                               
Title                                         title of work
Subtitle (not Subject)                the subtitle of the work 
Subject                                     the subject of the work  
Keyword                                    keywords

See https://wiki.contextgarden.net/Interaction PDF Header and Custom Properties.

Thanks for the PDF spec file. I will check it out for any hints about non-standard metadata.

Alan

Sorry, Alan, I’m afraid I don’t get your point.

  \setupinteraction
    [state=start,
     title=Title,
     author=Author,
     subtitle=Subject,
     keyword=Keyword]
  \starttext
  \null
  \stoptext

According to the PDF spec
(https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#nameddest=G13.2348400),
there is no editor field in standard metadata (unless you mean creator
or producer).

Just in case it might help,

Pablo
