Task
1Create updated DMI Registry Yang Schema (using @yyyy-mm-dd) in changelog/db/changes/data/yang-models/dmi-registry @ 2021-12-13.yang to store Handle State
2

Add StateLockReason and LockReasonDetails as (Yang)Strings to the schema. Any validation or enum-limitations can be handled in the Java code.

3

Consider timestamp modelSyncStartTimesyncStartTime for retry and timeout related scenarios as part of same schema update to reduce overhead of Liquibase changesets 

4

Test/demo using CPS-Core 

  1. Can create anchor with new schema
  2. Can add and create data
