The Target ID (TID)

Each target (object that can receive messages) receives an ID during registration. The target ID (short: TID) is of type ID and is unique for a target within a namespace. The same TID can exist again in other namespaces. This is used when loading multiple instances of apps.

If no TID is given when registering the target, then a "random" numeric TID is generated. This is the normal case.

If a TID is given, it will be used if no target with this ID has been registered in this namespace yet.

By using a name database it is possible to output a speaking string in the LOG instead of a randomly generated TID . - Innovative Distributed System
