doi's used in bonares typically do not resolve in crossref or openaire

What is the typical mechanism to make intermediaries such as OpenAire and Crossref aware of DOI's?

Asking because some of the Bonares DOI's seems not available in OpenAire and Crossref, others are

See https://api.crossref.org/swagger-ui/index.html#/Works/get_works__doi_ and try any of the doi's advertised in https://tools.bonares.de/doi/datasets/

Same for https://explore.openaire.eu/search/advanced/research-outcomes?f0=pid&fv0=10.20387%252Fbonares-1yhh-07w1, but findable for https://explore.openaire.eu/search/advanced/research-outcomes?f0=pid&fv0=10.20387%252Fbonares-43xt-vjpb

On the other hand Datacite and DOI itself returns them perfectly:

send a GET request to https://doi.org/10.20387/bonares-1yhh-07w1 with accept: application/x-bibtex

@misc{https://doi.org/10.20387/bonares-1yhh-07w1,
  doi = {10.20387/BONARES-1YHH-07W1},
  url = {https://maps.bonares.de/mapapps/resources/apps/bonares/index.html?lang=en&mid=b0b98713-a12e-47df-8911-c66305fd0c02},
  author = {Phalempin, Maxime},
  title = {Loam/Sand fitted parameters},
  publisher = {ZALF(Leibniz Centre for Agricultural Landscape Research (ZALF))},
  year = {2024},
  copyright = {Creative Commons Attribution 4.0 International}
}

For ISRIC DOI's such as 10.17027/isric-soilgrids.c6cb5073-78dd-4d8d-be81-9d546a1c004f, 10.17027/isric-soilgrids.f0797a68-1692-11ea-a7c0-a0481ca9e724, 10.17027/isric-soilgrids.713396fc-1687-11ea-a7c0-a0481ca9e724 , these are actually findable in OpenAire, but not in Crossref

Mendeley is one of the platforms which was actually able to resolve some of the Bonares and isric data sources
