+Validate release(d) version information
+---------------------------------------
+
+- Visit Maven Central.
+- Sanity check deployed pom.xml files contain correct
+
+  - Package and api versions.
+  - ONOS package version
+  - Dependent package version.
+
+- Yes an automation script should be created for this task.
+- A jenkins job can be run post deployment to perform validation.
+
+  - Input would be a config file containing expected versions.
+  - For complete coverage the job could be run:
+
+    - pre-release: validate incoming SNAPSHOT version(s).
+    - post-release: verify deployed artifact and pom.xml versions.
+    - post-validation: jenkins would increment expected versions.
+
+- TODO: Start by creating a config file populated with version strings.
+
+  - Static text can be used to maintain docs.voltha.org/release_notes/
+  - Config would also be used as input to voltha-release (hardcoded values).
