Dublin Core No.2

—For deeper understanding—

Abstract

This paper is the second half of the two consecutive articles on Dublin Core. The goal of this article is to describe fundamental issues of Dublin Core for deeper understanding. The issues include the roles of core metadata, the Warwick Framework, the concepts of qualifiers, the Dumb-down principle, element sets and application profiles. This article also explains Resource Description Framework (RDF), which is adopted as the infrastructure technology for metadata interoperability on the Web, and the organization structure of the Dublin Core Metadata Initiative (DCMI). Some discussions for future development of Dublin Core are given to conclude this article.
