Re: [EP-tech] DSpace Harvester and OAI_Bibliography.pm

I would exclude this format/plugin from oai2 in:

https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Feprints%2Feprints%2Fblob%2F3.3%2Fcgi%2Foai2%23L559&amp;data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7Cbf4319bea44c499bca5e08d81364c1dc%7C4a5378f929f44d3ebe89669d03ada9d8%7C0&amp;sdata=vuiqX0tBj5RP6i0fhVDlybI2EhuwfHLvGHggnIQLHb0%3D&amp;reserved=0

or you can change sort here (weak):

https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Feprints%2Feprints%2Fblob%2F3.3%2Fcgi%2Foai2%23L565&amp;data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7Cbf4319bea44c499bca5e08d81364c1dc%7C4a5378f929f44d3ebe89669d03ada9d8%7C0&amp;sdata=ySdc2CH1zcxEywn6m12iyC319ttNY%2FlAGNnXAlBfgvc%3D&amp;reserved=0
I think this is an issue in DSpace, it should use always oai_dc as default format (instead of checking schema, the OAI specs cite oai_dc).

Hi everyone...  in attempting to harvest some EPrinst repositories using DSpace harvester, the following issue was reported in 2016:

“What happens in this case is that EPrints has more than one entry for the supported metadata formats using OAI_DC (oai_bibl and oai_dc prefixes):

…
DSpace’s harvester is then selecting the first metadataPrefix, i.e. oai_bibl, for which EPrints is returning records with no metadata.”
Someone is having a similar issue now with EPrints repositories, so I’m wondering, is this still an issue, or was there a fix/modification added to EPrints for this?
I haven’t tried the solution to remove OAI_Bibliography.pm from the core files…
