[occi-wg] OCCI Link question

[Ralf Nyren]

Hi Florian,

You can do this by specifying both the NetworkInterface Kind and the
IPNetworkInterface Mixin in the "category=" parameter.

E.g.:
Link: </network/722bb908-0c48-11e1-b25e-00163e211147>;
  rel="http://schemas.ogf.org/occi/core#link";
  category="http://schemas.ogf.org/occi/infrastructure#networkinterface
http://schemas.ogf.org/occi/infrastructure/networkinterface#ipnetworkinterface";
  occi.networkinterface.mac="00:11:22:33:44:55";
  occi.networkinterface.interface="eth0";
  occi.networkinterface.address="192.168.0.2";
  occi.networkinterface.gateway="192.168.0.1";
  occi.networkinterface.allocation="static";
  X-OCCI-Attribute: occi.compute.cores=2

This allows inline creation of Links with associated mixins.

The relevant ABNF from the HTTP spec would be:
...
[ ";" "category" "=" link-type
... ]
link-type = type-identifier *( 1*SP type-identifier )

regards, Ralf
