The translation from JSON source data to tabular Congress data places the
limited resources of Congress developers in the way of the Congress users
having the flexibility to quickly try/use any data source and data field as
the need arises in their policy use cases. This spec is a proposal to
experiment with removing the translation step, thus retaining the source JSON
data model, as a promising way to overcome the limitation.

According to Openstack summit session [1],
stestr is maintained project to which all Openstack projects should migrate.
Let's switch to stestr as other projects have already moved to it.

Z3 is an open source automatic theorem prover developed by Microsoft.
This spec describes how to add Z3 as an alternative Datalog engine
in Congress.

In preparation to support more policy engines in addition to the standard
Congress policy engine (e.g., ones based on SQL, influxDB, or Z3), we need
explicit typing of table columns in the data sources and the
data service engine. This spec proposes to support explicit typing, including
custom types, in an extensible, evolutionary, and backwards-compatible manner.

This specification introduces a datasource driver and agents to collect
configuration files handled by the oslo-config library on the different
nodes and make them available to the congress datalog engine as a
datasource.

PollingDataSource class polls all data from related services once
the DataSource is initialized. If the polling spends long time
to fetch the data, even though any policy rule doesn't use some
of the DataSource's translator, it causes performance issue.
This spec resolves the performance issue by diasbling translator
to poll data.

Some applications require Congress to be highly available (HA). Some
applications require a Congress policy engine to handle a high volume
of queries (high throughput - HT).
This spec describes how we can support several deployment schemes that
address some HA and HT requirements.

Currently, Congress only has datasource drivers which polls data
from cloud service. This spec proposes a push type datasource driver
which receives data from cloud service.

The current nova provides availability zones but nova data source
driver does not support it. In order to give more flexible and

Currently Congress specs sphinx doc build broken,
all of the rst files can't be built into html files,
so previewing the html format of specs is impossible.
Fix it so that we can review specs in human readable way.
Some format issues exist in current rst files, so fix these
at the same time so that tox py27 and docs build can pass.

move specification from kilo to liberty
Abstract policy into "name", "object", "violation condition", "action"
and "data", and express this abstraction in Horizon. This abstraction
is not just a expression of datasource drivers, and it makes those
users who are not familiar with Datalog express their intent more
easily and intuitively.

-Clarify the meanings of abstraction elements and give some examples
-Give an example to show how the UI looks like and how to use it
