The Crossref XML Export Plugin can deposit DOIs to Crossref for registration in a variety of ways:
You can also register your content with Crossref entirely outside of OJS using the Crossref metadata manager, though the plugin can save you having to input metadata by hand.
You can find the Crossref Plugin from your dashboard by navigating to Tools > Import/Export > Crossref XML Export Plugin.
This is the Crossref XML Export Plugin in OJS 3.1.2+:
To enable automatic deposits, simply check the box on the settings page.
OJS will deposit assigned DOIs as content in your journal is published. OJS does this at specific timed intervals. If your DOIs do not appear to be registered shortly after publication, you can wait a day to see if they make it through the OJS process and the Crossref queue. You can also check the status of your DOI by clicking the “Articles” tab at the top of the Crossref plugin settings page. You’ll see an up-to-date status column on the right of the page.
Manual deposits are always enabled in OJS 3.1.2.
Validate XML will, when checked, confirm validation of your XML before submission to Crossref. It will inform you of potential submission issues. It is, however, not suitable for large deposits and may time out. It is best used to troubleshoot smaller deposits.
Mark Active will flag a DOI as submitted. Use this if you’ve already registered a DOI outside of the plugin and want to indicate as such.
Export XML will download XML generated by the plugin in the Crossref XML Schema. Simply click the check boxes next to the articles you want to deposit and then export. Once you have the XML file, you can submit it via the Crossref admin tool at https://doi.crossref.org.
Any time you make a change to an article’s metadata, you should update the metadata associated with your DOI registered with Crossref. Updates do not happen automatically. To update:
Crossref does not charge to update metadata.
