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
