Detailed Description

Parent class of Element.

MetaElement provides most of the services of Element. It has three roles:

• specify the interface of Element<S, T>,
• offer additional abstract services implemented using only services in the specified interfaces,
• link services to their external implementations.

Of course this class must be specialized over S and T, and no generic implementation is provided.

For additional genericity, the hierarchy between concepts should be mapped to a hierarchy of between their specialization of MetaElement.
