[occi-wg] OCCI-notifications

[Jean Parpaillon]

Hi Augusto, all,
Thanks for all the interesting discussions in OGF, first.

Regarding the notifications, we discussed 2 approaches:
- the first include the notion of notification into the meta-model, with
versions of it in each rendering/protocol
- the second one add categories for a notification system, hence a model

IMO, the second approach, hence simpler, has the problem of being
limited to notifications on resources. I don't see how to plug
notifications on collections, links or user mixins, for instance.

Have I missed somthing ?

Another possible approach should be to consider notifications only at
the level of protocol, not touching meta-model.

My opinion is we should first think about at which level we want to
introduce this notion of notifications.

Regards,
Jean
