Crossref XML plugin for OJS

If you use Open Journal Systems (OJS) you should use PKP’s OJS Crossref XML plugin to register your content with us. To make best use of the plugin, make sure you’re using OJS version 3 or higher. If you recently moved onto the OJS platform and have existing DOIs please read more information here.

You can set up the plugin to work in one of two ways:

  1. Register your content with us automatically using the OJS plugin
  2. Have the plugin create an XML file that you can then upload to our admin tool.

Setting up the plugin and credentials

If you plan to set up the plugin to register content with Crossref automatically, you’ll need to add your Crossref account credentials into the username and password field in the plugin.

OJS Crossref plugin settings
  1. Depositor name - Name of the organization registering the DOIs (note: this field is not authenticated with Crossref)
  2. Depositor email - email address of the individual responsible for registering content with Crossref (note: this field is not authenticated with Crossref)
  3. Username - the Crossref username that will be passed to us to authenticate your submission(s) (more on role versus user credentials below)
  4. Password - the password associated with your Crossref credentials

Note: if the combination of username and password is incorrect, OJS will return a 401 unauthorized status code error at the time of registration. This error indicates that the username and password are incorrectly entered. That is, they do not match the username and/or password set with Crossref.

  • If you are using organization-wide, shared role credentials, you can simply add in your shared username and password.
  • If you are using personal user credentials that are unique to you, you’ll need to add your email address and your role into the username field, and your personal password into the password field. Here’s an example of what this will look like:

Password: your Password
