We consider the information validation process one of the most important parts in any information system.

KEMETEX Information model provides four levels of validation:

1. The object definition may state which attributes are required and which are not.
2. Each data type performs its own validation (as mentioned in the previous section).
3. The object logic validation preformed by the Validation Extension.
4. Services in addition may provide custom validation and data integrity.
