Archival Resource Keys (ARKs) serve as persistent identifiers or stable trusted references for information objects. This plugin for OJS allows managing the persistent identifier ARK for articles, issues, and galleys. Installation and configuration for the plugin is documented in English and Spanish https://github.com/yasielpv/pkp-ark-pubid/wiki
We are in urgent need of an easy updatable version of this plugin for the current dnd future versions of OJS, OPS... Can you do that? Is someone working on it? Can we help you?
Unverified, but I've heard of article-level ARKs breaking after upgrading.
