[leshan-dev] Plan for a 0.9 or 1.0 version of Leshan

[Simon Bernard <contact@xxxxxxxxxxxxxxx>]

Hi all,

  Having a release for Leshan could be great. We're still waiting for a 
1.0 version of the spec, but we identify several points we would like to 
see for a first release of Leshan and we should focus on.

  You could find the identified issues here : 
https://github.com/eclipse/leshan/labels/1.0
  This is not specially ordered by priority. (all seems really 
essential except #198)

  To release Leshan we will also need a Californium release. We 
currently depends on the "persistent observationStore" which is in the 
2.0 branch.
  So if we want to release Leshan we also need to focus on a stable 
Californium release. Currently there is a lot changes in Californium, 
and I think we should identify a limited number of new feature we want 
for this release.
  Here is what it seems important to me:
     1)This issue seems essentials : 
https://github.com/eclipse/californium/issues/104.
     2)As I explain here[1], I think that correlate request/response by 
session/epoch is really too strong I would also be able to just made the 
correlation by Identity in Leshan. Having a way to do that in 
Californium by offering a way to implement your own correlator or by 
adding a new correlation mode could be a good point.
     3)(optional) ObservationStore currently identify an observation 
just by token. We should probably use an additional information like 
Identity or CorrelationContext to identify it.
  This 3 issues focus on security and observe behind NAT.
