Avoiding unnecessary traffic is the main the reason to use two separate nodes (data and metadata). Note that on the normal case you should only subscribe or advertise interest (Entity Caps) in the metadata node. That way you will receive lightweight notifications when the avatar is updated and only retrieve the data when needed. > I just set pubsub options to cancel these notifications like below, and the > server told me success, it's not OK. > > <iq type="set" > to="m...@fuyootrh" > id="config9"> > <pubsub xmlns="http://jabber.org/protocol/pubsub#owner";> > <configure node="urn:xmpp:avatar:data"> > <x xmlns="jabber:x:data" type="submit"> > <field var="pubsub#send_last_published_item"><value>0</value></field> > </x> > </configure> > </pubsub> > </iq> I don't know Openfire but, according to the protocol, '0' is not a valid value here. Try with 'never' or 'on_sub'. Also, as far as I know you need to submit the complete configuration form.
