Arxiv is no StandardField, you need to use eprint for this

Needs to be eprint

Thanks for your feedback! I see, I will change it.

You then should also add the correpsonding eprinttype field to arxiv

…v IDs.

@XYZ567AB You can add a code comment into StandardField.java to guide someone also working here. Saying how the arXiv ID is stored and also add a link to the Java class handling arXiv Ids and the functionality introduced at #11627.

+- We added functionality to handle arXiv ID in `PdfContentImporter` and implemented related test case. [#12000](https://github.com/JabRef/jabref/issues/12000)


These comments are user facing. A user does not see PdfContentImporter in the UI. We are updating the docs at JabRef/user-documentation#537 - and the updated section should be linked.

No! We have the class org.jabref.model.entry.identifier.ArXivIdentifier use this.
