Hi,

Nova emits notifications for many different event, like different 
instance actions[1]. Also the nova developer community is working on 
making nova notifications well defined and easy to consume [2].

The goal of this mail is twofold.

1) We in the nova developer community would like to see which projects 
are using (or planning to use) the nova notification interface. Also we 
would like to know if you are using the legacy unversioned 
notifications or the new versioned ones. We would like to know what are 
your use cases towards our notification interface and we also would 
like to get any type of feedback about the interface (both the old and 
the new one). Based on this information we can make better decision 
where to focus our development effort. As a good example we already 
have a  cooperation with the searchlight project to enhance nova's 
versioned notification interface based on their needs [3].

I opened an etherpad [4] to collect the projects and the feedback and 
we can go through that feedback in the PTG to define some actions.

2) Creating a well defined and easy to use notification interface gives 
us plenty of work in nova. So we are also looking for developers who 
can help us in this work. Big chunk of [2] is considered as low hanging 
fruit and I'm happy to mentor anybody who is interested learning this 
part of nova. If you want to join to this work just ping me (gibi) or 
IRC.

Cheers,
gibi
