Easy, just yaml them to find out how the serialized form should look:

   class Item

     attr_accessor :name
     attr_accessor :type
     attr_accessor :location

     def initialize
       @name = ""
       @type = ""
       @location = ""
     end

   end

   require 'yaml'
   y Item.new


If you run this you get:

--- !ruby/object:Item
location: ""
name: ""
type: ""


Then you can play with the string and check that YAML.load does the 
right thing on this data
