Hi Madhu,
If you are trying to expose data from a new service, you need to add a new
data-source driver (examples from nova and neutron are in the tree.) Once a
data-source driver is registered, data from the data source will be exposed
through the API automatically, and you will also be able to write policy based
on the data. (Note that using the current code in master your data source will
not be activated until it is referenced by a policy - a commit is in flight to
change that, however.)
If, instead, you are trying to expose non datasource data in the API, it would
involve implementing the DataModel interface (see api/webservice.py) and
binding it to a URI and handler in congress_server.py. If this is what you
want to do, please provide more details on what you are exposing and I can walk
you through it.

Subject: [openstack-dev] [Congress] Help in understanding API Flow
Hi,
Can some one help me understand how an API is exposed to the clients from
Congress server ?
I see that a cage service ('api-policy') is created in congress_server.py.
I believe this is implemented in policy_model. I tried to send a json_request
from my client on the server.
I tried sending list_members, get_items, PUT and POST as methods and
all these give me NotImplemented error response.
Any help in this direction ?
I also want to add new APIs and hence understanding the API flow is crucial.
Thanks,
Madhu Mohan
