The Dublin Core Metadata Initiative
Wednesday 7th December 2016

The Dublin Core Metadata Initiative

  • The Dublin Core Metadata Initiative (DCMI) is an organization dedicated to promoting the widespread adoption of interoperable metadata standards and developing specialized metadata vocabularies for describing resources that enable more intelligent information discovery systems.
  • The mission of DCMI is to make it easier to find resources using the Internet through the following activities:
  1. Developing metadata standards for discovery across domains,
  2. Defining frameworks for the interoperation of metadata sets, and,
  3. Facilitating the development of community- or disciplinary-specific metadata sets that are consistent with items 1 and 2
  • The Dublin Core Metadata Element Set is a vocabulary of fifteen properties for use in resource description. The name "Dublin" is due to its origin at a 1995 invitational workshop in Dublin, Ohio; "core" because its elements are broad and generic, usable for describing a wide range of resources.
  • The Dublin Core Metadata brought together librarians, digital library researchers, content experts, and text-markup experts to promote better discovery standards for electronic resources. The resulting metadata element set defines fifteen metadata elements for resource description in a cross-disciplinary information environment.
  • The fifteen element "Dublin Core" described in this standard is part of a larger set of metadata vocabularies and technical specifications maintained by the Dublin Core Metadata Initiative (DCMI). 
  • Since 1998, when these fifteen elements entered into a standardization track, notions of best practice in the Semantic Web have evolved to include the assignment of formal domains and ranges in addition to definitions in natural language.
  • Domains and ranges express the meanings implicit in natural-language definitions in an explicit form that is usable for the automatic processing of logical inferences. When a given property is encountered, an inferencing application may use information about the domains and ranges assigned to a property in order to make inferences about the resources described thereby.
