Example of an RSpec advertisement with just a single node.

Some component managers may only manage a single node. Their advertisements will be pretty straightforward and look something like the one below:

<?xml version="1.0" encoding="UTF-8"?>
<rspec xmlns="http://www.protogeni.net/resources/rspec/0.1"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.protogeni.net/resources/rspec/0.1 http://www.protogeni.net/resources/rspec/0.1/ad.xsd"
       type="advertisement"
       generated="2009-07-21T19:19:06Z"
       valid_until="2009-07-21T19:19:06Z" >
  <node component_manager_uuid="urn:publicid:IDN+emulab.geni.emulab.net+authority+cm"
        component_name="pc160"
        component_uuid="urn:publicid:IDN+emulab.geni.emulab.net+node+pc160" >
    <node_type 
      type_name="pc850"
      type_slots="1"
    />
    <node_type 
      type_name="pc"
      type_slots="1"
    />
    <available>true</available>
    <exclusive>true</exclusive>
    <interface component_id="urn:publicid:IDN+emulab.geni.emulab.net+interface+pc160:eth0"/>
    <interface component_id="urn:publicid:IDN+emulab.geni.emulab.net+interface+pc160:eth1"/>
  </node>
</rspec>
