This example uses the steps that are described in the Create an Empty Library Item procedure.

require 'Com/Vmware/Content/Library'
require 'securerandom'

# 1 - Create an instance of the ItemModel class to specify the item settings.
item_model =
   Com::Vmware::Content::Library::ItemModel.new
item_model.name = 'ESXi ISO image'
item_model.description =
   'ISO image with atest security patches for ESXi 5.5 as of 2/3/2015'
item_model.type = 'iso'

# 2 - Associate the new item with an existing library.
item_model.library_id = $my_library_id

# 3 - Create the new instance of the Item class, using the specified model.
idem_token = SecureRandom.uuid
item_stub =
   Com::Vmware::Content::Library::ItemService.new $my_stub_config
item_id = item_stub.create(create_spec=item_model,
                           client_token=idem_token)
