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 3.2+:
The Crossref XML Export Plugin can deposit DOIs to Crossref for registration in a variety of ways:
Automatic deposit can be configured to assist streamline the post-production process.
Manual deposit from the plugin interface might be used to selectively deposit content to Crossref. For example, if you’ve made minor changes to the metadata following submission. It might also be helpful if you’ve noticed that the automatic deposit is taking longer than normal to be processed.
Manual deposit using Crossref XML export and admin tool might be used if you opt to add additional metadata such as licensing information not currently being deposited through the Crossref XML plugin.
You can also register your content with Crossref entirely outside of OJS using Crossref’s Web Deposit Form, though the plugin can save you having to input metadata by hand.
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 3.2+.
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.
