Adding meta data to use jdownload for google scholar indexing

[seaj]

Hi 

I want to use the amazing JDownload for a scholarly website. The site needs to show certain meta data to be indexed by google scholar. 
Title, Author and publication date are mandatory and already exist in jdownload. I want to use the custom fields for each filed to generate the other fields  (pdf url, issue, volume, edition, etc) BUT meta data as the following needs to be included in each page:

<meta name="citation_title" content="The testis isoform of the phosphorylase kinase catalytic subunit (PhK-T) plays a critical role in regulation of glycogen mobilization in developing lung">
<meta name="citation_author" content="Liu, Li">
<meta name="citation_author" content="Rannels, Stephen R.">
<meta name="citation_author" content="Falconieri, Mary">
<meta name="citation_publication_date" content="1996/05/17">
<meta name="citation_journal_title" content="Journal of Biological Chemistry">
<meta name="citation_volume" content="271">
<meta name="citation_issue" content="20">
<meta name="citation_firstpage" content="11761">
<meta name="citation_lastpage" content="11766">
<meta name="citation_pdf_url" content="http://www.example.com/content/271/20/11761.full.pdf">


More info available at: https://scholar.google.com/intl/en/scholar/inclusion.html#indexing


I really appreciate if I could get some direction as which file(s), could I modify to add the extra meta tag included in the final page of each file.
Jdownload already shows these information on the page, I just want to be able to also, echo these as meta data.


Thank you for your help.

Hi seaj,
you will use the jD 'custom data fields' for this data?
Are you sure that this are enough?
Please check this at first.

Maybe should you create a small system plugin which added this data in the output page? 

But you can also add this in every 'view' file.
Example:
/component/com_jdownloads/views/download/tmpl/default.php
for the output from a single Download (details page).
