Reference Implementation Based on near-RT RIC

This section documents the details of the O-RAN App SDK which is primarily covering the implementation for near-RT RIC xApps.

information about how the O-RAN App SDK will evolve to cover other O-RAN apps can be found here.

Description

xappframework is a simple framework for rapid development of RIC xapps, and supports various services essential for RIC xapps such as RESTful APIs, RMR (RIC Message Routing), database backend services and watching and populating config-map changes in K8S environment. Currently there are three language specific frameworks: Python, Go, and C++. Features supported vary by each framework; please refer to the specific documentation for details.
