+Decision API
+#######################
+
+The Decision API is used by ONAP components that enforce policies and need a decision on which policy to enforce for a specific situation. The Decision API mimics closely the XACML request standard in that it supports a subject, action and resource.
+
+.. csv-table::
+   :header: "Field", "Required", "XACML equivalent", "Description"
+
+   "ONAPName", "True", "subject", "The name of the ONAP project making the call"
+   "ONAPComponent", "True", "subject", "The name of the ONAP sub component making the call"
+   "ONAPInstance", "False", "subject", "An optional instance ID for that sub component"
+   "action", "True", "action", "The action being performed"
+   "resource", "True", "resource", "An object specific to the action that contains properties describing the resource"
+
+It is worth noting that we use basic authorization for API access with username and password set to *healthcheck* and *zb!XztG34* respectively.
+Also, the new APIs support both *http* and *https*.
+
+For every API call, the client is encouraged to insert an uuid-type requestID as parameter. It is helpful for tracking each http transaction
+and facilitates debugging. Most importantly, it complies with Logging requirements v1.2. If the client does not provide the requestID in the API 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>`_,
+in the response of each API call, several custom headers are added::
+
+    x-latestversion: 1.0.0
+    x-minorversion: 0
+    x-patchversion: 0
+    x-onap-requestid: e1763e61-9eef-4911-b952-1be1edd9812b
+
+x-latestversion is used only to communicate an API's latest version.
+
+x-minorversion is used to request or communicate a MINOR version back from the client to the server, and from the server back to the client.
+
+x-patchversion is used only to communicate a PATCH version in a response for troubleshooting purposes only, and will be provided to the client on request.
+
+x-onap-requestid is used to track REST transactions for logging purpose, as described above.

+*************************************
 
-In ONAP the following Policy Types are supported. Each Policy Type is implemented as an application that extends the **XacmlApplicationServiceProvider**. For details on each implementation, please refer to the `applications submodule of the onap/xacml-pdp project <https://gerrit.onap.org/r/gitweb?p=policy/xacml-pdp.git;a=tree;f=applications;h=047878fe14851d8a51998e065b8aca583ed8c994;hb=refs/heads/master>`__.

+
+XACML PDP TOSCA Translators
+===========================
+
+The following common translators are available in ONAP for use by developers. Each is used or extended by the standard PDP-X applications in ONAP.
+
+StdCombinedPolicyResultsTranslator Translator
+---------------------------------------------
+A simple translator that wraps the TOSCA policy into a XACML policy and performs matching of the policy based on either policy-id and/or policy-type. The use of this translator is discouraged as it behaves like a database call and does not take advantage of the fine-grain decision making features described by the XACML OASIS 3.0 standard. It is used to support backward compatibility of legacy "configure" policies.
+
+`Implementation of Combined Results Translator <https://github.com/onap/policy-xacml-pdp/blob/master/applications/common/src/main/java/org/onap/policy/pdp/xacml/application/common/std/StdCombinedPolicyResultsTranslator.java>`_.
+
+The Monitoring and Naming applications use this translator.
+
+StdMatchableTranslator Translator
+---------------------------------
+More robust translator that searches metadata of TOSCA properties for a **matchable** field set to **true**. The translator then uses those "matchable" properties to translate a policy into a XACML OASIS 3.0 policy which allows for fine-grained decision making such that ONAP applications can retrieve the appropriate policy(s) to be enforced during runtime.
+
+Each of the properties designated as "matchable" are treated relative to each other as an "AND" during a Decision request call. In addition, each value of a "matchable property that is an array, is treated as an "OR". The more properties specified in a decision request, the more fine-grained a policy will be returned. In addition, the use of "policy-type" can be used in a decision request to further filter the decision results to a specific type of policy.
+
+`Implementation of Matchable Translator <https://github.com/onap/policy-xacml-pdp/blob/master/applications/common/src/main/java/org/onap/policy/pdp/xacml/application/common/std/StdMatchableTranslator.java>`_.
+
+The Optimization application uses this translator.
+
+GuardTranslator and CoordinationGuardTranslator
+-----------------------------------------------
+These two translators are used by the Guard application and are very specific to those Policy Types. They are good examples on how to build your own translator for a very specific implementation of a policy type. This can be the case if any of the Std* translators are not appropriate to use directly or override for your application.
+
+`Implementation of Guard Translator <https://github.com/onap/policy-xacml-pdp/blob/master/applications/guard/src/main/java/org/onap/policy/xacml/pdp/application/guard/GuardTranslator.java>`_
+
+`Implementation of Coordination Translator <https://github.com/onap/policy-xacml-pdp/blob/master/applications/guard/src/main/java/org/onap/policy/xacml/pdp/application/guard/CoordinationGuardTranslator.java>`_
+
+Native XACML OAISIS 3.0 XML Policy Translator
+-----------------------------------------------
+
+This translator pulls a URL encoded XML XACML policy from a TOSCA Policy and loads it into a XACML Engine. This allows native XACML policies to be used to support complex use cases in which a translation from TOSCA to XACML is too difficult.

 Monitoring Policy Types
 =======================
-These Policy Types are used by Control Loop DCAE microservice components to support monitoring of VNF's during Control Loops. The DCAE Platform makes a call to Decision API to request the contents of these policies. The implementation involves creating an overarching XACML Policy that contains the TOSCA policy as a payload that is returned to the DCAE Platform.

-======================================
-These Policy Types are similar to the guard Policy Types and are called by the Control Loop Drools PDP Engine to support guarding of Control Loops during runtime control loop execution. NOTE: For Dublin, these Policy Types are not tested by the Integration team and are available as prototypes.
+Guard and Control Loop Coordination Policy Types
+================================================
+These Policy Types are used by Control Loop Drools Engine to support guarding control loop operations and coordination of Control Loops during runtime control loop execution.

For example, when a new policy is loaded the translator copies the template to a new policy and replaces the CONTROL_LOOP_ONE and CONTROL_LOOP_TWO values with the specified control loops. See the `XAMCL Coordination Template for more details <https://gerrit.onap.org/r/gitweb?p=policy/xacml-pdp.git;a=blob;f=applications/guard/src/main/resources/coordination/function/onap.policies.controlloop.guard.coordination.FirstBlocksSecond.xml;h=bea05f264be5e422eb2da448d40057f736b7555c;hb=refs/heads/master>`__.

+  :language: JSON
 
 Optimization Policy Types
 =========================
-These Policy Types are designed to be used by the OOF Project support placement in ONAP. The OOF Platform makes a call to the Decision API to request these Policies based on the values specified in the onap.policies.Optimization properties that have a metadata property called "matchable" and its value is set to "true". NOTE: For El Alto, this is dark code and OOF has not yet upgraded to the new Decision API to support this. Please refer to the OOF Project for more details on how it currently uses the Legacy API and policy models in their platform.
+These Policy Types are designed to be used by the OOF Project support several domains including VNF placement in ONAP. The OOF Platform makes a call to the Decision API to request these Policies based on the values specified in the onap.policies.Optimization properties. Each of these properties are treated relative to each other as an "AND". In addition, each value for each property itself is treated as an "OR".

+
+The optimization application extends the StdMatchablePolicyTranslator in that the application applies a "closest match" algorithm internally after a XACML decision. This filters the results of the decision to return the one or more policies that match the incoming decision request as close as possible. In addition, there is special consideration for the Subscriber Policy Type. If a decision request contains subscriber context attributes, then internally the application will apply an initial decision to retrieve the scope of the subscriber. The resulting scope attributes are then added into a final internal decision call.

 Native XACML Policy Type
-=======================
+========================
+
 This Policy type is used by any client or ONAP component who has the need of native XACML evaluation. A native XACML policy or policy set encoded in XML can be created off this policy type and loaded into the XACML PDP engine by invoking the PAP policy deployment API. Native XACML requests encoded in either JSON or XML can be sent to the XACML PDP engine for evaluation by invoking the native decision API. Native XACML responses will be returned upon evaluating the requests against the matching XACML policies.

-Supporting Custom Policy Types
-******************************
-In order to support your own custom Policy Type that the XACML PDP Engine can support, one needs to build a Java service application that extends the **XacmlApplicationServiceProvider** interface and implement a **ToscaTranslator** application. Your application should register itself as a Java service application and expose it in the classpath used to be loaded into the ONAP XACML PDP Engine. Ensure you define and create the TOSCA Policy Type according to these :ref:`Policy Design and Development <design-label>`. You should be able to load your custom Policy Type using the :ref:`Policy Lifecycle API <api-label>`. Once successful, you should be able to start creating policies from your custom Policy Type.
+Supporting Your Own Policy Types and Translators

-See each of the ONAP Policy Type application implementations for for ONAP re-use the **StdXacmlApplicationServiceProvider** class. They give simple examples on how to use various implementations of **ToscaTranslator** applications.

+XacmlApplicationServiceProvider
+===============================
 
-Once your application is developed and the ONAP XACML PDP Engine can find your application via setting the classpath appropriately, then use the :ref:`PAP REST API <pap-label>` to ensure the ONAP XACML PDP is registering your custom Policy Type with the PAP. Once successful, then you should be able to start deploying the created policies to the XACML PDP Engine.

-Decision API
-************
-The Decision API is used by ONAP components that enforce policies and need a decision on which policy to enforce for a specific situation. The Decision API mimics closely the XACML request standard in that it supports a subject, action and resource.
+`Standard Application Service Provider implementation <https://github.com/onap/policy-xacml-pdp/blob/master/applications/common/src/main/java/org/onap/policy/pdp/xacml/application/common/std/StdXacmlApplicationServiceProvider.java>`_

-It is worth noting that we use basic authorization for API access with username and password set to *healthcheck* and *zb!XztG34* respectively.
-Also, the new APIs support both *http* and *https*.
+ToscaPolicyTranslator
+=====================
 
-For every API call, client is encouraged to insert an uuid-type requestID as parameter. It is helpful for tracking each http transaction
-and facilitates debugging. Mostly importantly, it complies with Logging requirements v1.2. If client does not provider the requestID in API call,
-one will be randomly generated and attached to response header *x-onap-requestid*.
+Your custom **XacmlApplicationServiceProvider** must provide an implementation of a *ToscaPolicyTranslator*.
 
-In accordance with `ONAP API Common Versioning Strategy Guidelines <https://wiki.onap.org/display/DW/ONAP+API+Common+Versioning+Strategy+%28CVS%29+Guidelines>`_,
-in the response of each API call, several custom headers are added::
