Class: Marpa::DcDatastream

Inherits:
ActiveFedora::NokogiriDatastream show all
Defined in:
lib/active_fedora/samples/marpa-dc_datastream.rb

Overview

This is an example of a NokogiriDatastream that defines a terminology for Dublin Core xml

Some things to observe about this Class:

  • Defines a couple of custom terms, tibetan_title and english_title, that map to dc:title with varying @language attributes

  • Indicates which terms should be indexed as facets using :index_as=>

  • Defines an xml template that is an empty dublin core xml document with three namespaces set

  • Sets the namespace using :xmlns argument on the root term

  • Does not override or extend to_solr, so the default solrization approach will be used (Solrizer::XML::TerminologyBasedSolrizer)
