The main issue with using path names for identifying configuration items is that path names are attributes of configuration items and thus, can also change. Assume for example that directories represent subsystems (e.g., storage, notification, user interface, train tracking). In the case of a change of the subsystem decomposition, the directory structure may change (e.g., the storage directory may be split into a database directory and a JDBC directory). For tools which use path names as identifiers, this translates into configuration items being deleted and added under a different path name. Since different versions of the same configuration items have different identifiers, operations such as merging branches are consequently not possible.
