This does sort of work except on quick usage a couple of problems.
If I define this,

\newcommand{\mjmaddbib}[2]{\hypersetup{ pdfinfo={ x-bib-#1 = {#2}}}}


And create a file with stuff like  this, 

\mjmaddbib{year}{\mjmbibyear}
\mjmaddbib{author1email}{\mjmemail}
\mjmaddbib{contact}{\mjmemail}
\mjmaddbib{author1id}{orcid.org/0000-0001-9237-455X}
\newcommand{\mjmpagesin}{ \input \mjmbasename.last_page }
%\mjmaddbib{pages}{\input{\mjmbasename.last_page}}
\mjmaddbibe{pages}{\mjmpagesin}
\mjmaddbib{filename}{\mjmbasename}

It sort of works except there are spaces in the key name
before numbers and the "input" is ignored in the pages entry
( this seems to work ok to make the human readable bibtex in the document) ,


exiftool -struct -f -x -ee allbib.pdf  | grep X-bib
X-bib-title                     : Adding Citation Features to Shares for e-Commerce, News, and other Non-academic Sites
X-bib-author                    : Mike J Marchywka
[...]
