Background:
The Policy Framework solution uses the TOSCA policy model as a way to allow users to access common Policy Framework capabilities. The model is extended for specific PDPs. All concepts supported in Policy Framework are extensions of the concepts specified in the standard TOSCA policy definition specification. The concept of Targets in the TOSCA specification is not implemented in common Policy Framework functionality. However, equivalent functionality can be realized using policies in existing PDPs e.g. to return a decision on a 'guard' policy, an XACML policy can be used, or to apply a filter an Apex policy could be used. Therefore to deploy Target like functionality in the Policy Framework, a PDP is deployed.
Scenario and Need(s):
It is proposed that a PoC should be executed to analyze how the Policy Framework could evolve to support the TOSCA specification for Targets while ensuring that the existing Policy Framework functionality and requirements are maintained.
