Cherry feature scope: Detailed list of JIRA items that we plan to work on in Cherry (requires LinuxFoundation login): link(28 items)

PTL: Thoralf Czichy

Status 2020-09-02: (a) I (PTL) am happy to see teams from Samsung and HCL joining the project with them actively working on capabilities related to the E2 simulator (actually in Alex' simulator project), more test automation (using the robot framework), benchmarking, SDL (shared data layer). (b) RIC-372 was the first commit from these new participants (c) we might be aiming for self-certification under LF's CII badge level "basic", (d) work on O1-related functions, like E1 and A1 statistics, or some alarms already done. (e) Adaptation to E2APv1.1 only happening post-Cherry.
