The project aimed to advance the ability to validate knowledge based systems. The objective was to develop a toolbox based on a common representation within which the validation concepts could be defined and analysed.

The research provided a knowledge based system (KBS) project leader with a quality manual that described the related actions to be performed during the whole KBS life cycle, and a toolbox that contained a validation metalanguage (VETA) and validation tools.
The KBS quality assurance and control gathers a set of actions to be done during the whole life cycle. The Quality Manual describes each action in regards to its goals, the validation tools required and the people involved in the action. VETA is a metalanguage that gathers around 1000 primitives dedicated to validation, working on a common conceptual knowledge representation (CCR). This CCR allows support to any KBS that deals with: knowledge representation based on objects and rules, monoinheritance, first order logic, rule set, metarules, etc. The validation tools have been developed within VETA.
7 validation tools cover a wide area of validation problems, ranging from purely practical validation tools to validation problems that are research topics.
The approach was to develop the following methodologies:

- the definition of a KBS quality manual, with special attention to validation actions during the different phases of KBS life cycles
- a common conceptual representation (CCR) in which most KBSs can be expressed
- the definition of a validation metalanguage (VETA) to provide the abstract mechanisms necessary to build validation tools.

These have provided the basis for several software products:

- an implementation of VETA;
- a set of representative tools for the validation of KBSs;
- interfaces to a set of existing KBSs.
