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

Use URL of registered Organization, the registered Organization URL
information is registered in MDR
Case 2

In case of registered and standardized metadata using registry system of
MDR administered Organization: Use URL of Organization that
administers MDR.
