Inconsistent import from Crossref search and Crossref DOI

[InAnYan]

JabRef version

5.15 (latest release)

Operating system

Windows

Details on version and operating system

Linux Mint 22 (XFCE)

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

User can have two versions of the same entry based on whether it was imported from search result or imported from DOI.

Consider this article: https://doi.org/10.36074/grail-of-science.13.10.2023.001. (I hope you won't be too scared of Ukrainian language 😄).

When searching in Crossref via title Важелі забезпечення ефективної цифрової трансформації України, it has this bib code:

@Article{Клєвцєвич,
  author    = {Наталія Клєвцєвич},
  journal   = {Grail of Science},
  title     = {ВАЖЕЛІ ЗАБЕЗПЕЧЕННЯ ЕФЕКТИВНОЇ ЦИФРОВОЇ ТРАНСФОРМАЦІЇ УКРАЇНИ},
  issn      = {2710-3056},
  number    = {32},
  pages     = {25-28},
  doi       = {10.36074/grail-of-science.13.10.2023.001},
  publisher = {European Scientific Platform (Publications)},
}

(I removed groups and file).

But when you use the DOI, you have this result:

@Article{Клєвцєвич202310,
  author    = {Наталія Клєвцєвич},
  journal   = {Grail of Science},
  title     = {ВАЖЕЛІ ЗАБЕЗПЕЧЕННЯ ЕФЕКТИВНОЇ ЦИФРОВОЇ ТРАНСФОРМАЦІЇ УКРАЇНИ},
  year      = {2023},
  issn      = {2710-3056},
  month     = oct,
  number    = {32},
  pages     = {25--28},
  doi       = {10.36074/grail-of-science.13.10.2023.001},
  publisher = {European Scientific Platform (Publications)},
}

I found this issue when imported entries from search didn't have a year field.

But when I imported via DOI, year was there.

Starting point: https://devdocs.jabref.org/code-howtos/fetchers.html

Ages ago, there was a discussion of a fetcher pipeline:. Keep Fetchers focussed. - pipejplibe should use fetcher, use doi fetcher, merge.

Or other ID fetcher. At ISBN we build kind of that ...
