Note that any newly discovered resource must have a unique resource key as compared to other sibling resources. That is to say, a parent resource's children must have unique resource keys (the children cannot share keys). A corollary to this is that if a discovery component "re-discovers" a resource, the discovery component must ensure that it assigns the same key to that re-discovered resource (i.e. resource keys must be consistent and stable across multiple discoveries of that same resource). As an example, if you discover a resource "foo" and assign it a resource key of "fooKey"; then the next time that "foo" resource is discovered again, the discovery component must ensure that it discovers it with the resource key "fooKey" again.
