Thank you Davide for a very interesting description of how XMPP solves many of the issues
related to Industry 4.0.
One reflection on what you wrote regarding thresholds and alarms:
Thresholds can be set to rise alarms in case some
parameters exceed
the optimal values.
This use case is managed in a general way by the proposed XEP IoT Events that I submitted
some time ago, but that the council wanted to change to use data forms instead of the more
XEP-0323-like approach that it uses today. My personal conviction is that such an approach
is highly counter productive and difficult to implement/validate and would effectively
kill the XEP, which is why I did not pursue the subject. But if interest exists, it might
be a good idea to brush off this proposal again, and re-address the issues in a pragmatic
manner.
