#solrize_relationships(solr_doc = Hash.new) ⇒ Object

Serialize the datastream’s RDF relationships to solr

Parameters:

def solrize_relationships(solr_doc = Hash.new)
  relationships.each_statement do |statement|
    predicate = Predicates.short_predicate(statement.predicate)
    literal = statement.object.kind_of?(RDF::Literal)
    val = literal ? statement.object.value : statement.object.to_str
    ::Solrizer::Extractor.insert_solr_field_value(solr_doc, solr_name(predicate, :symbol), val )
  end
  return solr_doc
end

#to_solr(solr_doc = Hash.new, opts = {}) ⇒ Object

Return a Hash representation of this object where keys in the hash are appropriate Solr field names. If opts == true, the base object metadata and the RELS-EXT datastream will be omitted. This is mainly to support shelver, which calls .to_solr for each model an object subscribes to.

Parameters:

  • solr_doc (Hash) (defaults to: Hash.new) —

    (optional) Hash to insert the fields into

  • opts (Hash) (defaults to: {}) —

    (optional)
