  1. OSC work on CM Handling (Nov 2021). The following page
    CM handling guide - Developer Wiki - Confluence (onap.org) 
    describes a CM VES message and procedure for handling it, especially mapping the schema url to a local url. This refers to a 3GGP Rel16 scheme which needs to be updated to https://forge.3gpp.org/rep/sa5/MnS/-/blob/Rel-18/OpenAPI/TS28532_ProvMnS.yaml
  2. ONAP work on defining a CM VES message. This is an older format and does not have a path specified, but may be useful in designing the solution
    https://jira.onap.org/secure/attachment/17656/CMNotificationFormat_son_poc.json
