Re: [occi-wg] Atompub: Can we see an example of top level storage and network rendering ?

      Thanks....

I'm assuming value multipliers like ,Kb, Gb, Tb  will be defined and we 
will delineate between bits, bytes and blocks. Note: they all "b"egin 
with "B"s

I would also like to see the current AtomPub example extended with
    a few actual attributes
    on the nouns (e.g. cpu cores, memory size, storage size) and
    showing a few
    example actuators (e.g. server start/stop, etc) since I understand
    that they
    will also appear in the feed.
Ok so for attributes I have thus far been adding them directly to the 
atom <entry> elements to keep things nice and flat and the <content> 
free for other purposes (e.g. expanding on a simple OCCI description 
of a compute or network resource with DMTF/OVF and SNIA standard 
descriptors respectively). For example:
<entry>
      <id>...</id>
      <compute:cores>4</compute:cores>
      <compute:memory>16Gb</compute:memory>
      ...
    </entry>
If you're worried about burning 1's and 0's on namespaces then you can 
trim them back:
<entry>
      <id>...</id>
      <c:cores>4</c:cores>
      <c:memory>16Gb</c:memory>
      ...
    </entry>
For the state transition links you need a few things:
* The link itself (URL)
    * A machine-readable identifier for the link (e.g.
      http://purl.org/occi/state#start)
    * A human-friendly identifier for the link in requested/local
      language (e.g. "Take Snapshot")
How this looks in atom:
<link title="Start" rel="http://purl.org/occi/state#start"
    href="http://example.com/{uuid}/state/start
    <http://example.com/%7Buuid%7D/state/start>" />
Note that anybody can create new transitions but those that may need 
to be interoperable would end up in our registries.
Cheers,
