This example uses the steps that are described in the Edit the Settings of a Library Item procedure.

require 'Com/Vmware/Content'
require 'Com/Vmware/Content/Library/Item'

# 1 - List the items in a published library.
item_stub =
   Com::Vmware::Content::Library::ItemService.new $my_stub_config
item_ids = item_stub.list $my_library_id

# 2 - List the files uploaded to each library item
#     and print their names and sizes.
file_stub =
   Com::Vmware::Content::Library::Item::File.new $my_stub_config
item_ids.each do |item_id|
  item = item_stub.get item_id
  file_infos = file_stub.list item_id
  file_infos.each do |info|
    puts "Library item #{item.name} has file #{info.name}" +
         " with size #{info.size}"
  end

# 3 - For a library item with a specified name,
#     create an ItemModel to change the name and description of the item.
  if item.name == 'simpleVmTemplate'
    puts "Library item '#{item.name}' with description" + 
         " '#{item.description}'"
    item_model =
       Com::Vmware::Content::Library::ItemModel.new
    item_model.name = 'newItemName'
    item_model.description = 'Description of the newItemName'
    item_stub.update(library_item_id=item_id,
                     update_spec=item_model)
    puts 'has been changed to:'
    puts "Library item '#{item_model.name}' with description" +
         " '#{item_model.description}'"
  end  # if item.name

end  # |item_id|
