Hi, Koha Developers. I wrote a Dublin Core metadata support to export in XML and RDF formats. This code follow the Dublin Core Specifications at: < http://dublincore.org/specifications/> specially DC-XML, Simple DC-RDF, and DC-RDF recommendations. Aditionally support OAI-DC schema at < http://www.openarchives.org/OAI/2.0/oai_dc.xsd>. RDF can be exported as multiple formats like: rdfxml, rdfjson, ntriples, turtle, etc. It was neccesary to create a custom module (C4::DublinCoreTransformer) to transform the object created by DublinCore::Record and MARC::Crosswalk::DublinCore. The module returns all the formats as string. I file a bug to test it at: < http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13642> Regards, -- Atte, Héctor Eduardo Castro Avalos Universidad de El Salvador Facultad Multidisciplinaria Oriental
