The keystone team has a new spec being proposed for the Ocata release, it
essentially boils down to adding properties / metadata for projects (for
We have somewhat had support for this, we have an "extras" column defined
in our database schema, whatever a user puts in a request that doesn't
match up with our API, those key-values are dumped into the "extras"
column. It's not a pleasant user experience, since you can't really "unset"
the data easily, or grab it, or update it. There's actually been patches to
keystoneclient for getting around this, but its rather hacky and hardcodes
a lot of values  
I've added nova and cinder here since the APIs that are being proposed are
more or less carbon copies of what is available through their APIs (for
server and volumes, respectively). What has been your project's experience
with handling metadata / properties? I assume that its been there a while
and you can't remove it. If you could go back and redo things, would you do
it another way? Would you take a more purist stance and enforce more strict
APIs, metadata be damned?
I also added horizon because i'm curious about the impact this causes when
representing a resource.
Personally, I am for the idea, we've had numerous requests from operators
about providing this support and I like to make them happy.
