Hi Michael,

My reasoning is that the philosophy of REST is to include links to context so if you are looking at something you can with a single link, find out what it pertains to. Outwith REST you'd usually do this by peeling back the path segments of the URL.

We could have sensor_resource point to sensors_resource instead, and sensors_resource point to camp_resource, but that felt less useful than having the camp_resource that the sensors list, or a sensor, (or an op or the ops list) referenced as a link.

Or we could do away with the context, there is no technical requirement, but in practice I find it helpful.

Good points about back pointers Tom, I was not suggesting that however.

I'm just wondering about the sensors (plural) to camp_resource as shown in the diagram.   The attribute target_resource is available from both the sensors and the sensor class.  Would having it available from just the sensor be sufficient?  Same question would apply to the link from operations (plural) to camp_resource.

Almost all of our associations have navigation in only one direction

Maintaining an array of back pointers from CampResource pointing at all its sensors is difficult and unnecessary.

The part of the UML model for sensors and operations is attached as a pdf file.

We do not put pointers in both directions unless there is a strong need.

Looks good Gil.

Is the model available?

Also, what is the require for the sensors (plural) to have a one to many link to the target resource vice just sensor to resource?  Just checking because the JSON sample seems to have just one link from Sensors to a target resource.  Maybe just having the individual sensor relationship to target resource is sufficient?

Submitter's message
Initial proposal lacking Tom's changes to the UML diagrams. Please check the description of the "characteristics" attribute of the "service resource" as that is the crucial piece of this proposal.
