Re: [EP-tech] DOI import support

Hi Yuri and Jens,
I think if the issue is retrieving metadata from CrossRef, then there is not much that can be done from an EPrints perspective.  In the most recent version of the DOI import plugin we have switched to using the unixref format [1] (e.g. https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdoi.crossref.org%2Fopenurl%2F%3Fpid%3Damail%40mail.com%26noredirect%3Dtrue%26format%3Dunixref%26id%3Ddoi%3A10.5281%2Fzenodo.7598185&data=05%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C88ab4db6fb4b4cc8362c08db709726a4%7C4a5378f929f44d3ebe89669d03ada9d8%7C0%7C0%7C638227566732152118%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=yKPbCp0bJjajHf%2FuCFpf5fx3kgBAHJBdORf%2Bnb%2FKUXk%3D&reserved=0 ).  This similarly returns no metadata and in fact the error message is even more vague than the message you received.  However, when I request the DOI you provide in the EPrints import plugin, I get an unhelpful error message.  Therefore, at least this DOI is useful to help improve the error output from an EPrints perspective, so it can better explains the error.

I get

but it resolves:

So the problem is on getting the metadata. There are a lot of metadata
format for DOIs (Crossref, Datacite...), so maybe DOIs without crossref
format cannot be imported?

Dear all,
I don't know if it has to do with this, but we have also received feedback from some submitters in the last few days that certain DOIs cannot be imported even though they are listed at Crossref. 

A few tests later we found out that there are differences between:
