Subject: RE: [camp] Groups - camp-spec-v1.1-wd45-173.doc uploaded

I see no problem with the current pointers.

Having "redudant" links from sensors to campResource and individual Sensor to campResource is an optimization.

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.

>> 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?
