Abbreviated journal title in Citation Style Language

Hi,

I am using the Citation Style Language plugin with PKP/OJS 3.1.1.4.

I would like to display the journal’s abbreviated name (container-title-short) rather than the (locale dependent) journal’s name, both in the article’s page and in the downloads for the different formats (BIBTeX, RIS … ).

Given that it is not a configuration option, which system file should I modify?

Many thanks.

Giuseppe.
