A suggestion by mjethanandani lead to a common definition for O-RAN-SC namespaces in YANG module:

• namespace "urn:o-ran-sc:specification:yang:xml:<yang-module-name>";

Note: o-ran-sc according to https://o-ran-sc.org I know a  lot of ppl use osc instead of o-ran-sc but osc conflics with https://www.osc.org/ http://osc.com – that is the main reason not using „osc“ in namespaces.

The change of the namespace should lead to a new revision statement in the yang modules:

revision 2021-03-?? {
  description
    "The namespace was updated according to O-RAN-SC yang guidelines.";
  reference
    "<link to this jira>";
}
