one of our editors asks if there is a way to add a button “Add metadata to Citavi / Endnote / Zotero”. I know there is the COins-Plugin for Zotero and you can use the Reading tools to export the metadata for Endnote (at least in the 2.4.8.1-Version of OJS we are currently using). But is there a tool which includes all three of the citation software solutions? Something which is a bit more visible or userfriendly?
It would be enough for us if there is something in development for OJS 3 as we are planning to upgrade in the near future.
AFAIK, RIS is still more or less universal format for any such applications. And all three apps you mentioned should read it without (significant) problems. OJS 3 supports exporting to RIS. OJS 2 should support it too.
COiNs plugin is useful for those apps, which may read metadata directly from the pages themselves.
However, I think it might be good if OJS supported those proprietary formats of each app you mentioned.
