Hi,
I'm going through the IoT discovery XEP (XEP-0347). In chapter 3.17 (disowning Thing)
the following is stated:
If such a Thing is found, and it is owned by the
caller, but not online as a friend, the Thing cannot be disowned, since it would put the
Thing in a state from which it cannot be re-claimed. Therefore, the Thing Registry must
respond in the following manner:
I am wondering about the piece "but not online as a friend". A
"friend" of whom? How should this be checked?
Wouldn't it be more practical to determine this situation by just sending the disowned
IQ message to the Thing?
When the server responds with a service-unavailable message it can be assumed that the
thing is currently offline (or at least unavailable). Otherwise there always should be a
friendship relation between the thing and the registry.
Cheers,
Eelco
