TODO.md

+[d] Evaluating policy synchronously
+    - Creating git infrastructure for the policies with the flow documentation. Will follow with feature branch with dev and production branch. Let's use [policies repo of the code.gitlab](https://code.vereign.com/gaiax/tsa/policies) to push policies. Git is a dependency should be preinstalled.
+  
+    - @kalin Create an environment to demonstrate
+        - Kubernetes
+        - Mongo Replicaset 1 primary and 2 secondary(v3.6)
+        - Redis
+    - Create a pipeline to sync the committed policy with MongoDB
+    - @yuli Create a script to syncrhonise the data from Git to Mongo 
+    - @dancho Sync policies from Mongo (replicaset deployment) with the policy services
+    + @penkovski Create a service with endpoint to evaluate the policy
+    - Create an example policy for the tests and demonstration
+    - @rosen Implement the test logic
+[] Implement the CI pipeline to test the service.
+    - imlement the simplest test.
+    - setup the Gitlab pipeline. Pick the simplest trigger event 
+
+[d] Distributed cache feature
+    - create Rego extensions
+    + create HTTP service
+    - create 2 example policies (1 for setting value, 1 for getting value)
+    - Implement the test logic 
+[] Persistance feature
+[] Resolving DID
+[] Evaluating policy asynchronously
+Evaluatating policy groups asynchronously
+Crypto libs to work with ursa (sign, key management)
+Policy to generate an endpoint in Kong
+Communication with OCM

features/distributedCache.feature

+As policy administrator
+I want to have distributed cache feature provided
+So I am able to use cache functionality in my custom policies
+
+Scenario: Working with cache
+Given one policy to set the value in the cache is uploaded to the system
+And the second policy to get the value from the cache is uploaded to the system as well
+When I evaluate policy to set the value in the cache
+And get a successful response
+When I evaluate policy to get the value from the cache
+Then I get a successful response
+And response body is not empty
+
+
+Acceptance criteria:
+- The plugin for rego language to get/set values is ready to use
+- The working example how to use the plugin
+- Green test based on example commited to the system
+  
+

features/evaluatePolicyAsync.feature

+As user
+I want to evaluate the policy asyncronously
+So I am able to execute the developed Rego code in the future non-blocking
+
+Scenario: Evaluate the policy asyncronously
+Given long running policy is uploaded to the system
+And the task template is uploaded to the system
+When I evaluate the policy asyncronously 
+And the task template is specifyed as an input
+When I get successful response
+And the response contains taskId
+
+Scenario: Getting the result for the executed policy
+Given long running policy is executed
+When I request the result of execution
+And request contains the taskId
+And the task has finished
+Then I get successful response
+And esponse contains the result of execution of the policy
+
+Acceptance criteria:
+- HTTP endpoints to evalute the policy asyncronously and get the result
+- example of long-running policy commited to Git repo
+- Green test based on example commited to the system

features/evaluatePolicySync.feature

+As user
+I want to evaluate the policy
+So I am able to execute it in the future
+
+Scenario: Execute the policy
+When I upload the policy to repository
+And set the policy to productive
+And the policy successfully uploaded to the system
+When I execute the policy
+Then I get successful response
+And response contains the result of execution of the policy
+
+Acceptance criteria:
+- HTTP endpoint to evaluate the policy
+- example policy created and commited to Git repo
+- Green test based on example commited to the system

features/persistance.feature

+As policy administrator
+I want to have persistence functionality 
+So I am able to store the json document inside of the database
+
+Scenario: Store data inside of database
+Given one policy to set the value in the database is uploaded to the system
+And the second policy to query the value from the database is uploaded to the system as well
+When I store the json document inside of the database
+And get a successful response
+When I evaluate policy to get the value from the database
+Then I get a successful response
+And response body is not empty
+
+Acceptance criteria:
+- plugin for rego language to set/query values is ready to use
+- example of usage of the plugin commited to the system
+- green tests based on example commited to the system

features/resolveDID.feature

+As policy administrator
+I want to evaluate resolving DID feature
+So I am able to use my DID features in the custom policies
+
+Scenario: DID resolution
+Given DID document is published
+And the policy to resolve did is uploaded to the system
+When I send a request containing DID
+And DID method is in the list of supported ones
+Then I get successful response
+And response contains DID document
+
+Acceptance criteria:
+- published did document
+- plugin for rego language to get/set values is ready to use
+- example of usage of the plugin commited to the system
+- green tests based on example commited to the system
