Hi,
To check LOADED(or ENABLED) data source drivers for a running system, you can
use congress cli. Maybe we could add a command to list SUPPORTED data source
drivers?
zhenzan@zhenzan-openstack:~$ openstack congress datasource list

Hi Bryan,
I wish we could claim Congress has most of the data from OpenStack APIs already
available for policy, but that's not the case today.
If it were me, I'd start with your use cases, figure out which services and API
calls you'll need to support those use cases, and then check if those APIs are
already available in Congress.

Thanks for clarifying, Tim (and Alex for the other response).
Since I have to understand the code anyway going to the drivers for current
info is reasonable.
Can I derive from your statement "One of Congress's goals is to make any data
available via an API call to policy-related" that Congress already exposes (in
Congress tables) most/all data available through OpenStack component APIs? That
would save me digging through the OpenStack code as well.

Hi, I have a question about where to find the complete set of currently

seems to cover only Nova and Neutron. I'm sure that I can pull this info from
the source at
https://github.com/stackforge/congress/tree/master/congress/datasources<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_stackforge_congress_tree_master_congress_datasources&d=AwMFAw&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=B6BWd4kFfgOzAREgThxkmTZKy7dDXE2-eBAmL0PBK7s&m=7K6Tq1uqgCY-gmJMedkayeCZgjUEWp7QD_HaJg6pHmY&s=XeNw_NiKGg3HrR5R6oVbN9EVV2RhB3CQ4waMWGvBAHM&e=>
but I was looking for any documentation on the current state of that code's
design. The existing blueprints (e.g. at
https://github.com/stackforge/congress-specs)<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_stackforge_congress-2Dspecs-29&d=AwMFAw&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=B6BWd4kFfgOzAREgThxkmTZKy7dDXE2-eBAmL0PBK7s&m=7K6Tq1uqgCY-gmJMedkayeCZgjUEWp7QD_HaJg6pHmY&s=AjqWychcmYYsMd9oOGytLq3rXOqzhJGLbUTi2OuX2_0&e=>
do not go into this detail AFAICT.
I'd definitely just do a directory listing on the source code. Syncing the
docs is something we do before a major release. Things are just changing too
quickly to do anything else.
Also, since I'm looking into how the current supported Congress tables will
support use cases of the OPNFV Copper project [1], it will be also helpful to
know where I would look for the set of potential policy-related data items
inside OpenStack docs/code for the various components. If I find a gap against
a use case, I would want to be able to specify related patches (e.g. where data
source driver extensions should get the additional data) so I need to know
where the data comes from (and what's available) inside OpenStack.
One of Congress's goals is to make any data available via an API call to
policy-related. So anything the API calls of OpenStack returns are reasonable
candidates for writing policy over.
