Hi In our library we are using Koha 21.11.10 We are trying to use OAI-PMH but when calling https://bibliothek.iunworld.com/cgi-bin/koha/oai.pl?verb=Identify the output is as follows: <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type='text/xsl' href='/opac-tmpl/xslt/OAI.xslt'?> <OAI-PMH xsi:schemaLocation='http://www.openarchives.org/OAI/2.0/ http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://www.openarchives.org/OAI/2.0/'> <responseDate>2024-04-03T16:39:53Z</responseDate> <request verb='Identify'>https://bibliothek.iunworld.com/opac/oai.pl</request> <Identify> <repositoryName>IUN World</repositoryName> <baseURL>https://bibliothek.iunworld.com/opac/oai.pl</baseURL> <protocolVersion>2.0</protocolVersion> <adminEmail>root@localhost</adminEmail> <earliestDatestamp>2020-01-21T13:25:14Z</earliestDatestamp> <deletedRecord>persistent</deletedRecord> <granularity>YYYY-MM-DDThh:mm:ssZ</granularity> <compression>gzip</compression> </Identify> </OAI-PMH> As you see in both the tags <request> and <baseURL> there is an incorrect URL ( https://bibliothek.iunworld.com/opac/oai.pl ) which only leads to a 404 error page. The correct URL would be https://bibliothek.iunworld.com/cgi-bin/koha/oai.pl I have changed the following line in file "/usr/share/koha/lib/Koha/OAI/Server/Identify.pm" to get the correct URL at least in tag <baseURL>: #baseURL => $baseURL, baseURL => 'https://bibliothek.iunworld.com/cgi-bin/koha/oai.pl', But I couldn't find out how to get the correct URL also in tag <request>. In fact I doubt what I'm doing is the correct way but I couldn't find any information in the manual on how to configure OAI-PMH except via the system preferences. Why is Koha showing the incorrect URL https://bibliothek.iunworld.com/opac/oai.pl at all and how can I change this?
