Hi all! I tried to validate a koha data provider with https://www.openarchives.org/Register/ValidateSite and get this two errors: *1. FAIL baseURL supplied 'https://mysite/cgi-bin/koha/oai.pl <https://mysite/cgi-bin/koha/oai.pl>' does not match the baseURL in the Identify response 'http://mysite/opac/oai.pl <http://mysite/opac/oai.pl>'. The baseURL you enter must EXACTLY match the baseURL returned in the Identify response. It must match in case (http://Wibble.org/ <http://Wibble.org/> does not match http://wibble.org/ <http://wibble.org/>) and include any trailing slashes etc.* *2. FAIL Bad earliestDatestamp: The earliestDatestamp in the identify response (2018-07-13 09:07:21) does not have the correct format for the time part of the UTCdatetime. The overall format must be YYYY-MM-DDThh:mm:ssZ.* I'm using Koha 18.05.01.000 with Plack (and memcached, no warnings/errors on *About > System Information*). Looking at my baseURL?verb=Identify XML I see <request verb='Identify'> http://mysite/opac/oai.pl</request> About first error, seems bug 17785 <https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=17785> but I look my code and this commit <https://github.com/Koha-Community/Koha/commit/1b492938e4eee4d1babe26417cfbf69cede2b844> is already applied, and should be already fixed on 18.05. I get similar (and others) errors trying with http://validator.oaipmh.com. Am I missing something? Using a YAML config file would be a workaround? I wonder what other people gets when validating <https://www.openarchives.org/Register/ValidateSite> their Kohas. Regards, Pablo
