Motivation
An MDR provides a good introduction to metadata concepts,
including a lot of insight into certain aspects of the granularity of
metadata
metadata
The MDR contributes knowledge integrity in a large scale

The simplicity provides the organization of implemental adaptation

The representational simplicity allows for easy sharing of metadata
Semantic Web promotes structured metadata representation,
such as an ontology schema that data concepts are associated
via relationships

For creating Web ontology, concepts are firstly defined and then
relationships are linked between the concepts
