Creating entry via mEDRA (using DOI) doesn't work

[sparusaurata]

When I try to create a new entry by giving a DOI with the mEDRA service, an error is raised:

… even if the DOI resolver at mEDRA.org finds the reference.

• JabRef version 5.2 on Linux Mint 20.1.
• Bug reproduced here.

Thanks for your report. It seemed maybe some temporary issue, or might be specific to your DOI. I tested a few DOIs with medra, but works for me. Can you please post your DOI here you tried?

I tried with this one: 10.5194/npg-24-569-2017 JabRef replies that mEDRA did not find any entry, but it works on mEDRA website.

JabRef 5.3--2021-04-26--add694a Linux 4.19.0-16-amd64 amd64 Java 15.0.2 JavaFX 16+8

Just use the normal DOI fetcher. JabRef will automatically check if the DOI belongs to medra or not. However, yours belongs to crossref and JabRef gets a HTTP 504 error, gateway timeout, so a problem on the CrossRef site. Totally odd.

I tried this one: 10.1016/0304-3975(95)00073-6.

Just use the normal DOI fetcher.

This what I initially wanted to do, but it didn't work (see here) so I used mEDRA as indicated in the docs.

I cannot reproduce this. The normal DOI fetcher works fine for me with your DOI. Mabye it was a temporary issue at CrossRef

Using Library --> New entry, both DOI (i.e. 10.5194/npg-24-569-2017 and 10.1016/0304-3975(95)00073-6) works using the ID type Crossef and DOI, but not using mEDRA. Any idea how long "temporary" could be?

I ran some tests:

mEDRA url: https://data.medra.org/10.3303/CET2184030

• GET request without http header "Accept: application/vnd.citationstyles.csl+json", it has been redirected many times, and the resource website can be accessed normally(in the browser).
• GET request with http header "Accept: application/vnd.citationstyles.csl+json", it directly gets the response result we want.

mEDRA url: https://data.medra.org/10.5194/npg-24-569-2017

• GET request without http header "Accept: application/vnd.citationstyles.csl+json", it has been redirected many times, and the resource website can be accessed normally(in the browser)(It redirected to https://doi.org/10.5194/npg-24-569-2017 and then to https://npg.copernicus.org/articles/24/569/2017/).
• GET request with http header "Accept: application/vnd.citationstyles.csl+json", its response is 404 not found.

Maybe this is a problem with mEDRA's API?

@Ryyyc You can test also with 'Accept: application/x-bibtex'

I think this is something on the Medra/DOI publisher side. I had this problem with other EU publications as well, they did not return bibtex but html from the website despite the Accept header. Maybe you can contact the support and ask them
