Hi all, So going back to this, I started to update the draft so that we will have more concrete propositions to discuss and update and we can also add comments to the doc to help with the discussions. So I added Authentication in the base Endpoint and I added the EndpointAuthentication_t type as open enumeration with 3 values: none, x509 and oidc. Do you think that it would make sense to add something like Authorization in the same way? I added Description (0..1) in the CloudComputingImage. And in the same way, I added Version (0..1) in order to document the image version (not the OS image version). I added the NetworkTrafficProtocol_t type as open enumeration. I added the NetworkTrafficDirection_t type as open enumeration but I think that here we want to enforce usage of inbound or outbound (vs bidrirectional) to ease the search. I added the NetwrokTrafficAddressRange_t type, a string in CIDR format. I added the NetworkTrafficPort_t type as a string and specified the list of accepted formats (80 or 80,443 or 25000:25009) So I'm a bit unsure about how all those NetworkTraffic* attributes should be structured in a single object/type, at first I think we were planning to add a new NetworkTraffic_t type and use it for two new NetworkInput and NetworkOutput attributes but I'm not sure it is possible to have a structure made of custom types, so should we add a NetworkTraffic entity under something like the "Conceptual Model fo the Cloud Computing Service" and associate them to the image? Or should we define something else or somewhere else? One last point, sorry, I don't know at all what the hell happend but while I was adding some content the google doc crashed and asked me to reload. But due to missing content I add to restore a previous version from some minutes ago. And then I saw in the comments threads than some very old suggestions from Salvatore Pinto were shown as rejected by me (but I never did it), I tried to reload some previous version from the same day but the comments did not change, so I manually accepted them as they were looking all appropriate and I found better to have them accepted than rejected and hidden, you should be able to see them in the comments thread window. If you prefer someone can try to revert to a previous version before my edit and if it fixes the comment I can re-add the content I've been adding today (I've downloaded exports).
