module ActiveTriples
  ##
  # Module to include configurable class-wide properties common to
  # RDFSources.
  #
  # Define properties at the class level with:
  #
  # @example
  #   configure base_uri: "http://oregondigital.org/resource/",
  #     repository: :default
  #
  # Available properties are base_uri, rdf_label, type, and repository
  module Configurable

      configuration[:base_uri]
    end

    def rdf_label

    ##
    # API for configuring class properties on a RDFSource. This is an
    # alternative to overriding the methods in this module.
    #
    # Can configure the following values:
    #  - base_uri (allows passing slugs to the RDFSource initializer
    #    in place of fully qualified URIs)
    #  - rdf_label (overrides default label predicates)
    #  - type (a default rdf:type to include when initializing a
    #    new RDFSource)
    #  - repository (the target persist location to for the RDFSource)
    #
    # @example
    #   configure base_uri: "http://oregondigital.org/resource/", repository: :default
    #
    # @param options [Hash]
    def configure(options = {})
      options = options.map do |key, value|

        end
        [key, value]
      end

    end

    def transform_type(values)
      Array.wrap(values).map do |value|
        RDF::URI.intern(value).tap do |uri|
