TYPING:
Identifies a programming language type conversion and characteristics. 
For instance, strong typing means that conversions between different data types in expressions require explicit conversions.
Typing is inherently Language Implementation Dependent

CONCURRENCY:
In distributed architectures, objects can be distributed across multiple processors. 
Since they are no longer controlled by a single process (program), their operations, states, and interactions must be controlled and coordinated in order to avoid resource contention and processing deadlocks.
Object Synchronization is Part of Distributed Objects

PERSISTENCE:
In distributed architectures or database applications, as a process terminates, the state of critical objects associated with the terminated process must be stored in a database or in a file. 
This provides persistence, i.e. objects from other processes can reactivate and interact with the persistent objects without loss of information.
How Objects / Agents Live is Part of Distributed Objects
