This document describes a YANG data model for SUPA (Simplified Use of Policy Abstractions) ECA (Event-Condition-Action) policies using policy abstractions defined in [I-D. strassner-supa-generic- policy-info-model]. The EPDM (ECA policy data model) is refined from SGPIM (SUPA Generic Policy Information Model)and EPRIM (ECA Policy Rule Information Model) to be applied to deliver various management policies for controlling managed entities throughout the service development and deployment lifecycle. The generic ECA policy data model could be augmented by additional YANG data modules modeling and configuring policy-related protocols and functions. Reusability as the major advantage of this approach can be realized. The policy data model described in this document provides common building blocks for such extensions.
