index.type :boolean for NtriplesRdfDatastream

[acurley]

Is it possible to index an attribute in an NtriplesRDFDatastream as a :boolean? I see from the specs that :date, :text and :integer are possible (and they work against the master branch of ActiveFedora) but :boolean seems unsupported.

module RDF
  class MyRDF < Vocabulary("http://example.com/terms/")
    property :has_boolean
    property :number
  end
end

class MyDatastream < ActiveFedora::NtriplesRDFDatastream
  map_predicates do |map|
    map.has_boolean(in: RDF::MyRDF) do |index|
      index.type :boolean
      index.as :stored_searchable
    end
    map.number(in: RDF::MyRDF) do |index|
      index.type :integer
      index.as :stored_searchable
    end
  end
end

class MyObject < ActiveFedora::Base
  has_metadata :name=>'rdf', :type=>MyDatastream
  has_attributes :has_boolean, :number, datastream: 'rdf', multiple: false
end

Given the above the following are true:

MyObject.defined_attributes[:has_boolean].type == :boolean
MyObject.defined_attributes[:number].type == :integer
MyObject.defined_attributes[:has_boolean].primary_solr_name == "rdf__has_boolean_bsi"
MyObject.defined_attributes[:number].primary_solr_name == "rdf__number_isim"

So far so good! But when it comes to .to_solr, things don't work for the :has_boolean column.

m = MyObject.create(has_boolean: true, number: 2)
pp m.to_solr => 
....
 "rdf__has_boolean_tesim"=>["true"],
 "rdf__number_isim"=>["2"],
...

I cannot figure out how or why the field changes from _bsi to _tesim. Any ideas?

It may not be possible now, but you could submit that as a pull request. Otherwise, I suggest overriding #to_solr on your datastream to manually add that field to the solr document.

This is patched in AF 7.0 RC3.
