Some Instance schema URI is missing in Collection schema URI Feb 22, 2021 3:30:29 GMT

Hi,

I found some wired cases about the relation between Collection and Instance schema URIs.

For example, NetworkPortCollection.json schema includes these uris :

"/redfish/v1/Chassis/{ChassisId}/NetworkAdapters/{NetworkAdapterId}/NetworkPorts",

"/redfish/v1/Systems/{ComputerSystemId}/NetworkInterfaces/{NetworkInterfaceId}/NetworkPorts",
...
...

But in NetworkPort.json schema, there is only one uri :

"/redfish/v1/Chassis/{ChassisId}/NetworkAdapters/{NetworkAdapterId}/NetworkPorts/{NetworkPortId}"

And this is not a single case, I also found NetworkDeviceFunction and NetworkDeviceFunctionCollection have the same problem.

Is there any reason for this design?

Thanks,
Alvin

Yes, those URI patterns are accurate. The intent is the members of "NetworkPorts" within "NetworkInterface" will point to the NetworkPort instances underneath Chassis. So, your "NetworkPortCollection" underneath systems will look like this:

{
    "@odata.id": "/redfish/v1/Systems/1/NetworkInterfaces/1/NetworkPorts",
    "@odata.type": "#NetworkPortCollection.NetworkPortCollection",
    "Name": "Network ports for interface 1",
    "Members": [
        {
            "@odata.id": "/redfish/v1/Chassis/1/NetworkAdapters/Adapter1/NetworkPorts/1"
        },
        {
            "@odata.id": "/redfish/v1/Chassis/1/NetworkAdapters/Adapter1/NetworkPorts/2"
        }
    ]
}

The same is true for NetworkDeviceFunctions. The reason for this is to allow for complex types of designs where physical ports and functions can be shared by multiple systems. So, in order to prevent duplication of resources, the collections under a given system will ultimately point back to their physical representation under chassis. I think we can add some additional language in the descriptions in NetworkInterface to make this clear.

We also have a YouTube video that explains this model here: www.youtube.com/watch?v=jJeHgvnUc3w

And yes I think it will be helpful if you can add some descriptions for this purpose. Thanks for your reply!
