1. Summary

The concept of linked data is to develop a form of linking data using the framework of Semantic Web (specifically using RDF triples). Here the word "data" is used, but it is closer to the concept of "instance." This is in contrast with "concept," the core of Semantic Web, and linked data is expected to be applied to practical cases because it uses a closer representation to entities in the real world.
