DOI metadata don't contain all authors

[ondracka]

Just a very minor thing. I have generated a DOI for my dataset https://dx.doi.org/10.17172/NOMAD/2021.09.15-2 and later I used www.doi2bib.org to generate a bibtex entry. However the bibtex entry shows only one author (myself, even though the entries from the upload have two authors).

That said I have no idea if this is a NOMAD bug or not, if the metadata is uploaded somewhere during the DOI creation or if this is just problem of the www.doi2bib.org site following the DOI to NOMAD and failing to extract the metadata from the page? So feel free to close as invalid...

I think this is on us and this is something we could change. The amount of metadata associated with a DOI is limited though. We have to check. Currently, we only add dataset creator to the DOI metadata.

I think it would make sense to search all entries in the dataset for authors and add all of them (the tricky part might the order, probably the dataset creator first and than the rest?). Usually manuscripts have multiple authors and there is no problem when using the DOI to citation/bibtex services, such as the https://citation.crosscite.org/ or the doi2bib.
