The OS names and versions received in telemetry is not necessarily the accepted common name.
normalized_os_version tables in the
static dataset serve as a
lookup table for mapping the telemetry name to the common name.
For OS names, Mac clients send
Darwin, Windows clients send
Windows_NT, and Linux may send the
Pings should already have a
normalized_os field that corrects this.
normalized_os_name table exists as an alternative lookup table.
ON (environment.system.os.name = os_name)
OS versions for some OS's are not properly normalized in telemetry. For example, the version
reported by Mac clients is the Darwin version instead of the MacOS version and the version
reported by Android Fennec clients is the Android SDK version instead of the Android version.
normalized_os_version table can be used to map the sent version to the "display version"
of the OS.
The table uses a regular expression to look up the OS version so
REGEXP_CONTAINS should be used.
