This is the point.

As you already found out, digikam supports mount paths as well and uses them 
as fallback if no UUID is available. Additional form can be added in the 
future (for the SQLite case and the hard drives you mentioned, one could think 
about a "relative to location of database" identifier). We definitely need 
better identifiers for network storage, we may need alternate identifiers to 
make things work cross-platform.

So we assume that the collection is located by some identifier, and that the 
files are available, as you say, by some file path. At runtime, we resolve the 
identifier to the current file path of the location. The path can also change 
at runtime (plug in a removable device) and is never written to the database.
