C4::OAI::Repository - Handles OAI-PMH requests for a Koha database.
use C4::OAI::Repository; my $repository = C4::OAI::Repository->new();
This object extend HTTP::OAI::Repository object. It accepts OAI-PMH HTTP requests and returns result.
This OAI-PMH server can operate in a simple mode and extended one.
In simple mode, repository configuration comes entirely from Koha system preferences (OAI-PMH:archiveID and OAI-PMH:MaxCount) and the server returns records in marcxml or dublin core format. Dublin core records are created from koha marcxml records tranformed with XSLT. Used XSL file is located in koha-tmpl/intranet-tmpl/prog/en/xslt directory and choosed based on marcflavour, respecively MARC21slim2OAIDC.xsl for MARC21 and MARC21slim2OAIDC.xsl for UNIMARC.
In extende mode, it's possible to parameter other format than marcxml or Dublin Core. A new syspref OAI-PMH:ConfFile specify a YAML configuration file which list available metadata formats and XSL file used to create them from marcxml records. If this syspref isn't set, Koha OAI server works in simple mode. A configuration file koha-oai.conf can look like that:
