Hello Boris,
I have one comment on your OCCI Compute Resource Templates. This specification does not explicitly define in which category (Kind or Mixin) the attribute eu.egi.fedcloud.occi.compute.ephemeral is defined. It could be defined in each of the six mixins or as I did it could be defined in an ephemeral mixin inherited by the six mixins. I prefer the second solution, which factorizes common elements of the six mixins.
it might not be explicitly mentioned there, but we adopted the first approach you mentioned. We had a few reasons for doing that: 1.) the whole point of that attribute is setting a default value different for each of those six mixins ; therefore it would have to be "included" in all of them anyway ... and in a separate additional mixin if we adopted the second approach (6 vs. 7 mixins with that attribute) 2.) we do not use OCCI for modeling purposes, features such as attribute inheritance from related mixins are not implemented ; this means that defining an attribute in one mixin and setting a default value for that attribute in a different related mixin wouldn't work 3.) this is all about practical applications for OCCI Infrastructure ; we made it as simple as possible If that makes any sense to you ...
A+ Philippe
Cheers, Boris

Hello everyone,
I have here, for your consideration, one of the first "formal" outputs of EGI FedCloud's work with OCCI -- The OCCI Resource Template Profile. We would very much like to hear your opinions, comments and/or suggestions.
After this (brief, hopefully) internal discussion phase, we would like to push for a public comment phase as soon as possible.
Thank you!
Cheers, Boris --- CESNET / EGI FedCloud
