All A1 policies instances in the network. Each policy is targeted to a Nearnear-RT-RIC instance and is owned by a 'service' (R-APP or the NONRTRIC Dashboard).
All Nearnear-RT-RICs in the network. This information can be maintained using the ONAP CDS database (which is using the Cloudify Consul database) or using a plain text file.
All Policy types supported by each Nearnear-RT-RIC

The service provides :

Unified REST API for managing A1 Policies in all near-RT-RICs.
A DMAAP DMaaP API for A1 Policy management.
Synchronized view of A1 Policy instances for each R-APP
Synchronized view of A1 Policy instances in each Nearnear-RT-RIC
Synchronized view of A1 Policy types supported by each Nearnear-RT-RIC
Lookup service to find the Nearnear-RT-RIC to control resources in the RAN as defined in O1 (e.g. which Nearnear-RT-RIC should be accessed to control a certain CU or DU, which in turn controls a certain cell).
Monitors all Nearnear-RT-RICs and maintains data consistency – e.g. recovery from Nearnear-RT-RIC restarts
Support for different Southbound APIs to the Nearnear-RT-RICs (different versions of the A1-P and other similar APIs).

...
