The hwinfo extension to rspecs
''''''''''''''''''''''''''''''

Grid'5000's AM implements an experimental extension to `advertisement rspecs`_ to help tool developpers expose additional information about the different `hardware_type` advertised by an Aggregate Manager.

For extensibility, this additional information is exposed as a list of different media-types information is available under.

A general example can be viewed here:

.. code-block:: xml

  <rspec xmlns="http://www.geni.net/resources/rspec/3" xmlns:hwinfo="https://doc.fed4fire.eu/rspec/ext/hwinfo/1" >
    <!-- ... -->
    <hwinfo:hardware_type_info>
      <hwinfo:overview media-type="text/plain">Short textual overview</overview>
      <hwinfo:overview media-type="text/html" href="https://doc.ilabt.imec.be/ilabt-documentation/virtualwallfacility.html#virtual-wall-2"/>
  
      <hwinfo:hardware_type name="pcgen05" hrn="Generation 5">
         <hwinfo:info media-type="text/plain">
           1x 4 core E3-1220v3 (3.1GHz), 16GB RAM, 1x 250GB harddisk, 2-10 gigabit connections
         </hwinfo:info>

      </hwinfo:hardware_type>
      <hwinfo:hardware_type name="pcgen04" hrn="Generation 4">
