How does DOI System metadata relate to the Dublin Core Metadata Initiative?
Dublin Core aims to be an easy-to-create and maintain descriptive format to facilitate cross-domain resource discovery on the Web. “Qualified Dublin Core” supports the use of DC elements as the basis for extended but simple statements about resources, rather than as a foundation for more descriptive clauses. Complex descriptions may be necessary for some Web resources and for some purposes, such as administration, preservation, and reference linking. However, complex descriptions require more expressive data models that differentiate between agents, documents, contexts, events, and the like. This is achieved through the indecs model. While DC starts from a small group of “core” elements, and DOI Application Profiles include a small group of “kernel” elements, the two do not serve the same purpose. The kernel is derived from a comprehensive data model and has strict rules for mandating implementation.
