 Policy Administration Point (PAP) Architecture
-----------------------------------------------
+==============================================
 .. toctree::
-   :maxdepth: 1
 
+The PAP keeps track of PDPs, supporting the deployment of PDP groups and the
+deployment of a *policy set* across those PDP groups.  Policies are created
+using the Policy API, but are deployed via the PAP. 
 
+A PAP is stateless in
+a RESTful sense, using the database (persistent storage) to track PDPs and
+the deployment of policies to those PDPs. In short, policy management on PDPs
+is the responsibility of PAPs; management of policy sets or policies by any
+other manner is not permitted.
 
+Because the PDP is the main unit of scalability in the Policy Framework, the
+framework is designed to allow PDPs in a PDP group to arbitrarily appear and
+disappear and for policy consistency across all PDPs in a PDP group to be
+easily maintained.  The PAP is responsible for controlling the state across
+the PDPs in a PDP group. The PAP interacts with the Policy database and
+transfers policy sets to PDPs.
+
+
+REST API
+--------
+
+PAP supports the operations listed in the following table, via its REST API:
+
+.. csv-table::
+   :header: "Operation", "Description"
+   :widths: 25,70
+
+   "Health check", "Queries the health of the PAP"
+   "Statistics", "Queries various statistics"
+   "PDP state change", "Changes the state of all PDPs in a PDP Group"
+   "PDP Group create/update", "Creates/updates PDP Groups"
+   "PDP Group delete", "Deletes a PDP Group"
+   "PDP Group query", "Queries all PDP Groups"
+   "Deploy policy", "Deploys one or more policies to the PDPs"
+   "Undeploy policy", "Undeploys a policy from the PDPs"
+
+
+DMaaP API
+---------
+
+PAP interacts with the PDPs via the DMaaP Message Router.  The messages listed
+in the following table are transmitted via DMaaP:
+
+.. csv-table::
+   :header: "Message", "Direction", "Description"
+   :widths: 25,10,70
+
+   "PDP status", "Incoming", "Registers a PDP with PAP; also sent as a periodic heart beat; also sent in response to requests from the PAP"
+   "PDP update", "Outgoing", "Assigns a PDP to a PDP Group and Subgroup; also deploys or undeploys policies from the PDP"
+   "PDP state change", "Outgoing", "Changes the state of a PDP or all PDPs within a PDP Group or Subgroup"
+
+
+PAP REST API Swagger
+--------------------
+
+It is worth noting that we use basic authorization for access with user name
+and password set to *healthcheck* and *zb!XztG34*, respectively.
+
+For every call, the client is encouraged to insert a uuid-type *requestID* as
+parameter. It is helpful for tracking each http transaction and facilitates
+debugging. More importantly, it complies with Logging requirements v1.2. If
+the client does not provide the requestID in a call, one will be randomly
+generated and attached to the response header, *x-onap-requestid*.
+
+In accordance with `ONAP API Common Versioning Strategy Guidelines <https://wiki.onap.org/display/DW/ONAP+API+Common+Versioning+Strategy+%28CVS%29+Guidelines>`_,
+several custom headers are added in the response to each call:
+
+.. csv-table::
+   :header: "Header", "Example value", "Description"
+   :widths: 25,10,70
+
+   "x-latestversion", "1.0.0", "latest version of the API"
+   "x-minorversion", "0", "MINOR version of the API"
+   "x-patchversion", "0", "PATCH version of the API"
+   "x-onap-requestid", "e1763e61-9eef-4911-b952-1be1edd9812b", "described above; used for logging purposes"
+    
+
+.. swaggerv2doc:: swagger/health-check-pap.json
+
+.. swaggerv2doc:: swagger/statistics-pap.json
+
+Note: while this API is supported, most of the statistics
+are not currently updated; that work has been deferred to a later release.
+
+.. swaggerv2doc:: swagger/state-change-pap.json
+
+.. swaggerv2doc:: swagger/group-pap.json
+
+Note: due to current limitations, if a subgroup is to be deleted from a PDP
+Group, then the policies must be removed from the subgroup in one request,
+and then the subgroup deleted in a subsequent request.
+
+.. swaggerv2doc:: swagger/group-delete-pap.json
+
+.. swaggerv2doc:: swagger/group-query-pap.json
+
+.. swaggerv2doc:: swagger/policy-deploy-pap.json
+
+Note: the policy version is optional.  If left unspecified, then the latest
+version of the policy is deployed. On the other hand, if it is specified, it
+may be an integer, or it may be a fully qualified version (e.g., "3.0.2").
+
+.. swaggerv2doc:: swagger/policy-undeploy-pap.json
+
+Note: if the policy version is specified, then it
+may be an integer, or it may be a fully qualified version (e.g., "3.0.2").
+On the other hand, if left unspecified, then the latest deployed version
+will be undeployed.
+
+Note: due to current limitations, a fully qualified policy version must
+always be specified.
