this is the DM agreed to R2 and maintenance release page version 20.
the final R3 DM is still under discussion.
any change to this page done by someone other then Victor Gao or Michael Lando will be reverted thank you.

We also need to check the defintion of tosca.capabilities.nfv.Metric in OASIS TOSCA, and figour out why it is derived from Endpoint capability.

Regarding the Monitoring feature we also need to consider the ONAP VES use case where the monitoring events should be handled. To my understanding there is no applicable support in IFA011 spec.

Monitor model here is not enough to be coded and is TBD later.
I see some capablities derived from tosca.capabilities.Node and some derived from tosca.capabilities.Root. Is there some principle?
shitao li
Good question. I think, they should all be derived from tosca.capabilities.Root, not tosca.capabilities.Node.
maopeng zhang
All listed derived from Root maybe are reasonable.
Alexander Vul
We need to align with the specs, not with what is reasonable...
maopeng zhang
So I do not change it, and let us to discuss the issues. If it is a problem, maybe we need to submit the issues. Now the SOL is also a draft, not a final one.
shitao li
we need to change the spec as well. I will do next week.
Arturo Martin de Nicolas
So you are bring this up to the TOSCA YAML, right? Personally I don't see either what's the purpose on deriving some capabilities from capabilities.node instead of from capabilities.root.
maopeng zhang
If discuss the issue, please info me. thanks

I think one thing is missing in tosca.capabilities.nfv.VirtualCompute, the ephemeral root local disk size, which means the amount of disk space to use for the root (
/
) partition to be launched with for a VM. This information is required to create OpenStack flavors.maopeng zhang
My suggestions:
1, The local_disk as a property in the virtualComputer. such as simple tosca compute node.
2, or add a local_disk node, related capacity and relationship,...
In the local disk, mostly it is created with the computer. Option 1 is OK in my mind.
Haibin Chu
I also think option 1 is a better approach. Besides that, the name of "local_disk" sounds a little bit confusing to me, because image could also be a local disk for the virtual compute. Maybe we can just call it "ephemeral" to align the name in VIMs, e.g. Openstack.

Someone keeps changing the definitions of the HPA attributes from
type: map
required: xxxx
to
type: map
entry_schema:
entry: string
required: xxxx
Why?
Alexander Vul
maopeng zhang - is there a reason you changed the type of vdu_storage requirements as described above?
maopeng zhang
Alexander Vul If defined a map in tosca, the entry_schema is needed
shitao li
HI Alex
I think maopeng is correct. Based on TOSCA grammar, for defining a key/value pair, the type of the property should be "map" and the entry_schema is string.
<entry_key_1>: <entry_value_1>
...
<entry_key_n>: <entry_value_n>
for example:
<some_entity>:
...
properties:
emails:
type: map
entry_schema:
description: basic email address
type: string
constraints:
- max_length: 128

It was brought to my attention that tosca.capabilities.nfv.VirtualStorage was not included. Thus, I update the wiki page with tosca.capabilities.nfv.VirtualStorage definition.
