/**
 * Get externalized strings to identify various operating system concepts. These
 * strings can be used in views and analyses to have a common term to identify
 * often used concepts, or as keys for searches and filters by the user.
 *
 * These strings are meant to be used and viewed by the user. Internally, they
 * may be translated into fixed non-externalized strings for actual
 * manipulation. Example: views will display TID in english, SvQQ in klingon,
 * searches for a thread ID would be written TID == 123 in english, SvQQ == 123
 * in klingon or eventually thread.tid in non-externalized (but maybe less
 * discoverable) concepts.
