![]() ![]() The spatial or temporal topic of the resource, spatial applicability of the resource, or jurisdiction under which the resource is relevant. Section 2: Properties in the /terms/ namespace Where applicable, the following attributes provide additional information about a term:Īdditional information about the term or its application.Īuthoritative documentation related to the term.Ī property of which the described term is a sub-property.Ī class of which the described term is a super-class.Ī class of which the described term is a sub-class.Ī class of which a resource described by the term is an instance.Ī suggested class for subjects of this property.Ī class of which a value described by the term is an instance.Ī suggested class for values of this property.Īn enumerated set of resources (Vocabulary Encoding Scheme) of which the term is a member.Ī class of which the described term is an instance.Ī property to which the described term is equivalent. The type of term: property, class, datatype, or vocabulary encoding scheme. The Uniform Resource Identifier used to uniquely identify a term.Ī statement that represents the concept and essential nature of the term. The human-readable label assigned to the term. The /dcam/ namespace was created in 2008 for terms used in the description of DCMI metadata terms.Įach term is specified with the following minimal set of attributes:Ī token appended to the URI of a DCMI namespace to create the URI of the term.The /dcmitype/ namespace was created in 2001 for the DCMI Type Vocabulary, which defines classes for basic types of thing that can be described using DCMI metadata terms.While the /elements/1.1/ namespace will be supported indefinitely, DCMI gently encourages use of the /terms/ namespace. The most useful properties and classes of DCMI Metadata Terms have now been published as ISO 15836-2:2019. While these distinctions are significant for creators of RDF applications, most users can safely treat the fifteen parallel properties as equivalent. As a result, there exists both a dc:date ( ) with no formal range and a corresponding dcterms:date ( ) with a formal range of "literal". In 2008, in the context of defining formal semantic constraints for DCMI metadata terms in support of RDF applications, the original fifteen elements themselves were mirrored in the /terms/ namespace. The /terms/ namespace was originally created in 2001 for identifying new terms coined outside of the original fifteen-element Dublin Core.This namespace corresponds to the original scope of ISO 15836, which was published first in 2003 and last revised in 2017 as ISO 15836-1:2017 [ ISO 15836-1:2017. The /elements/1.1/ namespace was created in 2000 for the RDF representation of the fifteen-element Dublin Core and has been widely used in data for more than twenty years.In Linked Data, the URIs for DCMI namespaces are often declared as prefixes in order to make data, queries, and schemas more concise and readable. The scope of each RDF schema corresponds to a "DCMI namespace", or set of DCMI metadata terms that are identified using a common base URI, as enumerated in the DCMI Namespace Policy. Term URIs resolve to the ( DCMI Metadata Terms) document when selected in a browser or, when referenced programmatically by RDF applications, to one of four RDF schemas. Such users can take domain, range, subproperty, and subclass relations as usage suggestions and focus on the natural-language text of definitions, usage notes, and examples.Įach term is identified with a Uniform Resource Identifier (URI), a global identifier usable in Linked Data. Creators of non-RDF metadata can use the terms in contexts such as XML, JSON, UML, or relational databases by disregarding both the global identifier and the formal implications of the RDF-specific aspects of term definitions. These terms are intended to be used in combination with metadata terms from other, compatible vocabularies in the context of application profiles.ĭCMI metadata terms are expressed in RDF vocabularies for use in Linked Data. The "Dublin Core" plus these extension vocabularies are collectively referred to as "DCMI metadata terms" ("Dublin Core terms" for short). Included are the fifteen terms of the Dublin Core™ Metadata Element Set (also known as "the Dublin Core") plus several dozen properties, classes, datatypes, and vocabulary encoding schemes. This document is an up-to-date, authoritative specification of all metadata terms maintained by the Dublin Core™ Metadata Initiative. Properties in the /elements/1.1/ namespace: Properties in the /elements/1.1/ namespace.This document is an up-to-date specification of all metadata terms maintained by the Dublin Core Metadata Initiative, including properties, vocabulary encoding schemes, syntax encoding schemes, and classes. ![]()
