Yes, that is definitely a solution. However you will only have to PUT the  
full
representation of the resource as far as Links are concerned, if I  
understand
things correctly.

So in order to increase the memory of a compute resource the sequence would
be:
1. GET /compute/xxx
2. Remember all Links with class='link'
3. Issue PUT /compute/xxx with occi.compute.memory = X and include
all the links from step 2.

In other words all Links must always by present in a PUT while only those
attributes one wishes to change has to be present. Correct?

Yep, as long as the deleting of a resource removes all Links but no other
resources I am happy.
