# Key_value[Key_size-8]

An array of 8-bit integers, each containing the actual name of the metadata key.

## Overview

Overview Keys with the ‘mdta’ namespace use a reverse DNS naming convention. For example, the location metadata coordinates use a metadata key_value of ‘com.apple.quicktime.location.ISO6709’.
