GUIDs/UUIDs are just "unique" values.

Think of them as something like a database table's Counter/AutoNumber ID field primary key, or Enum values, etc. Each one simply stands in for something else, sometimes conceptual.

Like an Enum value, each one is assigned a "meaning" someplace else. Usually in some purpose-oriented directory. XML namespaces use URIs in much the same way.

You'd need to find the appropriate dictionary of WMA GUIDs and their meanings.


It's like the old bit about some guys stranded on an island for years who have told every joke everyone knows time after time. So now every so often somebody just calls out "37!" and everyone chuckles just a little bit.
