In the scholarly communications environment, the evolution of a journal article can be traced by the relationships it has with its preprints. Those preprint–journal article relationships are an important component of the research nexus. Some of those relationships are provided by Crossref members (including publishers, universities, research groups, funders, etc.) when they deposit metadata with Crossref, but we know that a significant number of them are missing. To fill this gap, we developed a new automated strategy for discovering relationships between preprints and journal articles and applied it to all the preprints in the Crossref database. We made the resulting dataset, containing both publisher-asserted and automatically discovered relationships, publicly available for anyone to analyse.
The second half of 2023 brought with itself a couple of big life changes for me: not only did I move to the Netherlands from India, I also started a new and exciting job at Crossref as the newest Community Engagement Manager. In this role, I am a part of the Community Engagement and Communications team, and my key responsibility is to engage with the global community of scholarly editors, publishers, and editorial organisations to develop sustained programs that help editors to leverage rich metadata.
STM, DataCite, and Crossref are pleased to announce an updated joint statement on research data.
In 2012, DataCite and STM drafted an initial joint statement on the linkability and citability of research data. With nearly 10 million data citations tracked, thousands of repositories adopting data citation best practices, thousands of journals adopting data policies, data availability statements and establishing persistent links between articles and datasets, and the introduction of data policies by an increasing number of funders, there has been significant progress since.
Have you attended any of our annual meeting sessions this year? Ah, yes – there were many in this conference-style event. I, as many of my colleagues, attended them all because it is so great to connect with our global community, and hear your thoughts on the developments at Crossref, and the stories you share.
Let me offer some highlights from the event and a reflection on some emergent themes of the day.
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.
Depositor name - Name of the organization registering the DOIs (note: this field is not authenticated with Crossref)
Depositor email - email address of the individual responsible for registering content with Crossref (note: this field is not authenticated with Crossref)
Username - the Crossref username that will be passed to us to authenticate your submission(s). This might also be an email address - more on role versus user credentials below.
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:
In addition to the Crossref XML plugin for OJS, there are also other important plugins that can be enabled in OJS to enrich your metadata records:
Reference linking and deposit plugin - As of OJS 3.1.2, it is possible to enable a reference linking plugin for Crossref. The plugin will use the Crossref API to check against plain text references and locate possible DOIs for articles. The plugin will also allow the display of reference lists on the article landing page in OJS and deposit them as part of your metadata deposit. Linking references is a requirement of Crossref membership.
Crossmark plugin - OJS 3.2 includes support for Crossmark, which gives readers quick and easy access to the current status of an item of content, including any corrections, retractions, or updates to that record.
Similarity Check plugin - if you are using OJS 3.1.2 or above, you are able to use the Similarity Check plugin. This will enable you to automatically send manuscripts to your iThenticate account to check their similarity to already published content. You will need to be subscribed to Crossref’s Similarity Check service for this to work.
Getting help with OJS plugins
The team at Crossref didn’t create these plugins - they were either created by the team at PKP, or by third party developers. Because of this, we aren’t able to give in-depth help or troubleshooting on problems with these plugins.
If you need more help, you can learn more at PKP’s Crossref OJS Manual, plus there’s a very active PKP Community Forum which has more information on how to modify your OJS instance to submit metadata and register DOIs with Crossref.
