-Policy life cycle API comprises of policy design API and policy deployment API. This documentation focuses on policy

+The purpose of this API is to support CRUD of TOSCA *PolicyType* entities. This API is provided by the
+*PolicyDevelopment* component of the Policy Framework, see the :ref:`The ONAP Policy Framework Architecture
+<architecture-label>` page. Policy design API backend is running in an independent building block component of policy framework
 that provides REST service for aforementioned CRUD behaviors. Policy design API component interacts with a policy database
 for storing and fetching new policies or policy types as needed. Apart from CRUD, API is also exposed for clients to retrieve
 healthcheck status of this API REST service and statistics report including a variety of counters that reflect the history
 of API invocation.

 To be specific, the following rules are implemented to enforce the version:
 
-1. If the version is not in the database, we simply insert it. For example: if policy version 1.0.0 is stored in the database and now
+1. If the incoming version is not in the database, we simply insert it. For example: if policy version 1.0.0 is stored in the database and now
    a client wants to create the same policy with updated version 3.0.0, this POST call will succeed and return "200" to the client.
 
-2. If the version is already in the database, "406 - Not Acceptable" will be returned along with the message saying "specified version x.x.x"
-   is already existing and the latest version is y.y.y. It can force the client to create a newer version than the latest one.
-   For example, if policy versions "1.0.0" and "2.0.0" are already in the database and a client wants to create version "1.0.0" again, the
-   client will get "406" code returned along with the message "specified version 1.0.0 is already existing and the latest version is 2.0.0".
-   Then the client can change the version to anything newer than "2.0.0", such as "3.0.0".
+2. If the incoming version is already in the database and the incoming payload is different from the same version in the database,
+   "406 - Not Acceptable" will be returned. This forces the client to update the version of the policy if the policy is changed.
+
+3. If a client creates a version of a policy and wishes to update a property on the policy, they must delete that version of the policy and re-create it.
 
-3. If multiple policies or policy types are included in the POST payload, policy API will also check if duplicate version exists in between
+4. If multiple policies are included in the POST payload, policy API will also check if duplicate version exists in between
    any two policies or policy types provided in the payload. For example, a client provides a POST payload which includes two policies with the same
    name and version but different policy properties. This POST call will fail and return "406" error back to the calling application along with a
    message such as "duplicate policy {name}:{version} found in the payload".
 
-4. The same version validation is applied to legacy types of policies and policy types too (i.e. legacy guard and operational) so that everything
-   is consistent.
+5. The same version validation is applied to policy types too.
 
-5. To avoid unnecessary id/version inconsistency between the ones specified in the entity fields and the ones returned in the metadata field,
+6. To avoid unnecessary id/version inconsistency between the ones specified in the entity fields and the ones returned in the metadata field,
    "policy-id" and "policy-version" in the metadata will only be set by policy API. Any incoming explicit specification in the POST payload will be
    ignored. For example, A POST payload has a policy with name "sample-policy-name1" and version "1.0.0" specified. In this policy, the metadata
    also includes "policy-id": "sample-policy-name2" and "policy-version": "2.0.0". The 200 return of this POST call will have this created policy with
    metadata including "policy-id": "sample-policy-name1" and "policy-version": "1.0.0".

-It is worth noting that guard policy name should start with one of the three: *guard.frequency.*, *guard.minmax.*, or *guard.blacklist.*.
-Otherwise, it will complain that guard policy type cannot be found (does not exist). Apart from policy name, the policy version specified
-in API path should be an integer, e.g. 1, 2, 10, instead of "1.0.0", "2.0.1", etc.
-These naming restrictions will disappear after we evolve to use well-formed TOSCA Service Template for guard policies and
-legacy policy design API is then deprecated.

-Likewise, the policy version specified in operational policy API path should be an integer too, e.g. 1, 2, 10, instead of
-"1.0.0", "2.0.1", etc. This restriction will disappear after we deprecate legacy policy design API in the near future release.

-Regarding DELETE APIs for both TOSCA policies and legacy policies, we only expose API to delete one particular version of policy
+Regarding DELETE APIs for TOSCA compliant policies, we only expose API to delete one particular version of policy
