The core of the architecture is a micro-kernel (the MELDC

kernel), which encapsulates a minimum set of entities that

cannot be modelled as objects. All components outside of the

kernel are implemented as objects in MELDC itself and are

modularised in the MELDC libraries. MELDC is reflective in

three dimensions: structural, computational and architectural.

The structural reflection indicates that classes and

meta-classes are objects, which are written in MELDC. The

computational reflection means that object behaviours can be

computed and extended at run time. The architectural

reflection indicates that new features/properties

(e.g. persistency and remoteness) can be constructed in MELDC.
