            :with => /\A[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]+\z/
          }
        }
      }, {

        :type => Date
      }
    ]
  }, {
    :name => 'Employee',
    :extends => 'Person',
    :includes => %w(Mongoid::Timestamps),
    :fields => [
      {
        :name => 'birthdate',
        :validators => {
          :presence => true

    ]
  }

Build your models :

Mongoid::ModelBuilder.load('config/models.rb')
 => [Person, Employee]

Person.new
 => #<Person _id: ..., _type: "Person", name: nil, email: nil, birthdate: nil>

Employee.new
 => #<Employee _id: ..., _type: "Employee", name: nil, email: nil, birthdate: nil, salary: 1000>
