Re: [iot-wg] Integrating Eclipse IoT projects

Hi Bob,

thanks for your detailed response :-) I have added some comments below ...

That's great to hear!

At Bosch we are using KeyCloak for that purpose. Since it is also used by
enMasse, it is an obvious option for that purpose.

I cannot promise anything (yet) but our friends from RedHat are also working in
this direction, so I guess there is an excellent opportunity for collaboration.

So far we have deliberately chosen to not put any work into this because it would
be tightly coupled with the management API exposed by the device registry
implementation. Since this API is not in Hono's scope, there is no such thing yet
in Hono. However, this might be a good topic to discuss in the wider context of

I agree that it would be great to have a common "provisioning API" shared by Hono
and Ditto. However, an implementation of this API would (again) depend on the
management API of the device registry used by Hono so there (currently) is not
much room for a "standard" implementation. This seems to be a topic that is
bothering many people, though, so it also seems to be a good topic to discuss in
the context of integration.
