"Dublin" refers to Dublin, Ohio, USA where the work originated during the 1995 invitational OCLC/NCSA Metadata Workshop
-
"Core" refers to the metadata terms as "broad and generic being usable for describing a wide range of resources".
-
The Dublin Core Metadata Initiative (DCMI)[9] provides an open forum for the development of interoperable online metadata standards for a broad range of purposes and of business models.
-
The Dublin Core standard includes two levels: Simple and Qualified. Simple Dublin Core comprises 15 elements; Qualified Dublin Core includes three additional elements (Audience, Provenance and RightsHolder), as well as a group of element refinements (also called qualifiers) that refine the semantics of the elements in ways that may be useful in resource discovery.

The Simple Dublin Core Metadata Element Set (DCMES) consists of 15 metadata elements:[4]
-
Audience, Provenance and RightsHolder are elements, but not part of the Simple Dublin Core 15 elements. Use Audience, Provenance and RightsHolder only when using Qualified Dublin Core.
-
metadata is in a form suitable for interpretation both by machines and by human beings.
-
The Dublin Core Abstract Model[14] provides a reference model against which particular Dublin Core encoding guidelines can be compared, independent of any particular encoding syntax. Such a reference model allows implementers to gain a better understanding of the kinds of descriptions they are trying to encode and facilitates the development of better mappings and translations between different syntaxes.

Flavio CarvalhoThe Dublin Core metadata terms are a set of vocabulary terms which can be used to describe resources for the purposes of discovery. The terms can be used to describe a full range of web resources: video, images, web pages etc and physical resources such as books and objects like artworks [1]. The full set of Dublin Core metadata terms can be found on the Dublin Core Metadata Initiative (DCMI) website [2]. The original set of 15 classic [3] metadata terms, known as the Dublin Core Metadata Element Set [4] are endorsed in the following standards documents:
IETF RFC 5013 [5]
ISO Standard 15836-2009 [6]
NISO Standard Z39.85 [7].
Dublin Core Metadata can be used for multiple purposes, from simple resource description, to combining metadata vocabularies of different metadata standards Metadata#Metadata standards, to providing interoperability for metadata vocabularies in the linked data cloud Linked data and semantic web implementations Semantic web -

In addition to element refinements, Qualified Dublin Core includes a set of recommended encoding schemes, designed to aid in the interpretation of an element value. These schemes include controlled vocabularies and formal notations or parsing rules. A value expressed using an encoding scheme may thus be a token selected from a controlled vocabulary (for example, a term from a classification system or set of subject headings) or a string formatted in accordance with a formal notation (for example, "2000-12-31" as the standard expression of a date). If an encoding scheme is not understood by an application, the value may still be useful to human reader.
