OJS 3.4.0-5: Missing metadata on crossref registration (references and affiliations)

Hello everyone,

We’re currently encountering an issue with metadata registration in OJS: article affiliations and references are systematically missing from the Crossref export.
We are using OJS 3.4.0-5, Crossref XML Export Plugin and Crossref Reference Linking
We’ve checked the Crossref website to verify whether any registration errors occurred, but found no conflicts.
The journal website and submissions are configured in English, as shown below:

All other metadata appear to be properly registered, so we’re not sure what went wrong with the affiliations and references.
One clarification: so far, we’ve only registered articles via the Quick Submit Tool, not through the full submission workflow—if that could make a difference.
Crossref schema used is 5.3.1 (I don’t know how to configure it)

You can see an exemple below :
here is the article on our website (affiliations and references are correctly reported):
https://journals.sorbonne-universite.fr/Viemilieu/article/view/59/version/59
References:

affiliations:

Here is the XML export results :

<jats:abstract xmlns:jats=“http://www.ncbi.nlm.nih.gov/JATS1” xml:lang=“en”>
jats:pWater scarcity threatens crops, in particular, durum wheat (Triticum durum Desf.), in the world’s drought regions. As the water-stress wheat cultivars in the middle east of Algeria are poorly investigated, the present study was, therefore devoted to exploring the effect of water deficiency and, the possible attenuative role of exogenous hydrogen peroxide (H2O2) in Sémito, a commonly cultivated durum wheat (Triticum durum Desf.) variety in the middle eastern regions of Algeria. Here, Water-stressed durum wheat seeds received sufficient water for 48 hours to allow for uniform seed germination and then were subjected to cease the watering phase. The attenuation of water stress severity was examined in water-stressed wheat seeds treated with two different concentrations of H2O2 (20 and 50 mM). Water stress significantly reduced mean root number (MRN), mean root length (MRL), and germination percentage (G %), in addition to a marked decline in total protein content, and increased level of proline content and catalase activity compared to control plants. Moreover, H2O2 co-treatment enhanced the catalase activity, and promoted the accumulation of proline and protein contents, contributing to osmotic adjustment under water stress conditions. Our findings suggest that exogenous H2O2 application ameliorates water stress-induced physiological and biochemical changes in durum wheat, highlighting its potential as a promising strategy to enhance drought tolerance in this economically important crop species.</jats:p>

Hello everyone,

I’m reaching out again regarding the issue I posted earlier, as we haven’t received any replies yet.

To summarize: we’re having trouble with metadata export in OJS 3.4.0-5 — article affiliations and references are consistently missing from the Crossref XML export, although all other metadata appears to be correctly registered.

If anyone has come across a similar issue or has any suggestions, we’d be very grateful for your help!

Thanks a lot in advance!

Hi @hfinez, happy to help! Could you share which version of the Crossref plugin you’re using as well?

Hello @ewhanson ,
Thank you for your response, you can see below the plugin we are using :

--Plugin Crossref :
<version>
        <application>crossref</application>
        <type>plugins.generic</type>
        <release>3.0.0.0</release>
        <date>2021-03-29</date>
</version>

--Plugin crossref reference linking :
<version><application>crossrefReferenceLinking</application>
        <release>2.0.0.0</release>
        <date>2023-07-17</date>
        <lazy-load>1</lazy-load>
        <sitewide>1</sitewide>

Thank you very much!

Hello everyone, hello @ewhanson, we still wondering why metada aren’t properly registered with Crossref. Is it possible that our plugins are not up to date?
Thanks!
Hadrien
