One of our OJS journals, Journal of Organization Design (JOD) http://www.jorgdesign.net/index
, is using DOI. The pre- and suffix are registered under The Setup. But unfortunately I do not get any DOI informations when I make an export to RefWorks via the 'How to Cite'. We're running the 188.8.131.52 version of OJS.
On the PKP Wiki I see that you mention a DOI plugin, but I can't find it under the Systems Plugins. Is it because of the version?
We are testing the 184.108.40.206 and there I find it under Systems Plugins > Public Identifier Plugins and not under Generic (as you mention in the Wiki).
Perhaps I need that plugin to make the DOI visible under the metadata?
