search(:apps) do |app|
  (app["server_roles"] & node.roles).each do |app_role|

    app["type"][app_role].each do |thing|
      node.run_state[:current_app] = app
      include_recipe "application::#{thing}"
    end
    app["type"]["#{app_role}_definitions"].each do |thing|
      node.run_state[:current_app] = app
      eval %Q{#{thing} "#{app['id']}-#{thing}"}
    end

  end

Hm. Where did I get that definitions are deprecated? Anyway. Putting the 
stuff of reusable parts of the application cookbooks into
"resource groupings" aka definitions does work.
