Overview

OaiPmh::Metadata::OaiDc

Only one form of metadata is supported out of the box. Dublin Core is the most basic form of metadata, and the one recommended for support in all OAI-PMH repositories.

To add additional metadata types it’s easiest just to subclass OaiPmh::Metadata::OaiDc. Subclasses should override header(xml) to ouput a valid metadata header. They should also set defaults for prefix, schema, namespace, element_ns, and fields.

Example

class CdwaLite < OaiPmh::Metadata::OaiDc
  prefix = 'cdwalite'
  schema = 'http://www.getty.edu/CDWA/CDWALite/CDWALite-xsd-draft-009c2.xsd'
  namespace = 'http://www.getty.edu/CDWA/CDWALite'
  element_ns = 'cdwalite'
  fields = [] # using to_cdwalite in model

  def self.header(xml)
    xml.tag!('cdwalite:cdwalite',
     'xmlns:cdwalite' => "http://www.getty.edu/CDWA/CDWALite",
     'xmlns:xsi' => "http://www.w3.org/2001/XMLSchema-instance",
     'xsi:schemaLocation' => 
       %{http://www.getty.edu/CDWA/CDWALite 
         http://www.getty.edu/CDWA/CDWALite/CDWALite-xsd-draft-009c2.xsd}) do
       yield xml
    end
  end
end

# Now register the new metadata class
OaiPmh.register_metadata_class(CdwaLite)
