4. Not specific to any particular control system software. Flexible
Design
Not specific to any particular control system software.
Flexible
Easy implementation of new specifics.
Applications have to be tested without being modified.
The user must be able to write extensions in a language and platform of his choice.

6. Multi-platform multi-threaded CORBA server
Implementation
Multi-platform multi-threaded CORBA server
in C++ language
Multi-language, multi-platform clients can be created.
Advantages of the CORBA infrastructure can be exploited.
