This schema declares XML elements for the 15 Dublin Core elements in the "http://purl.org/dc/elements/1.1/" namespace. This is the default type for all of the DC elements. It defines a complexType SimpleLiteral which permits mixed content but disallows child elements by use of minOcccurs/maxOccurs. However, this complexType does permit the derivation of other types which would permit child elements. The scheme attribute may be used as a qualifier to reference an encoding scheme that describes the value domain for a given property. A name given to the resource. Typically, Title will be a name by which the resource is formally known. An entity primarily responsible for making the content of the resource. Examples of Creator include a person, an organization, or a service. Typically, the name of a Creator should be used to indicate the entity. A topic of the content of the resource. Typically, Subject will be expressed as keywords, key phrases, or classification codes that describe a topic of the resource. Recommended best practice is to select a value from a controlled vocabulary or formal classification scheme. An account of the content of the resource. Examples of Description include, but are not limited to, an abstract, table of contents, reference to a graphical representation of content, or free-text account of the content. An entity responsible for making the resource available. Examples of Publisher include a person, an organization, or a service. Typically, the name of a Publisher should be used to indicate the entity. An entity responsible for making contributions to the content of the resource. Examples of Contributor include a person, an organization, or a service. Typically, the name of a Contributor should be used to indicate the entity. A date of an event in the lifecycle of the resource. Typically, Date will be associated with the creation or availability of the resource. Recommended best practice for encoding the date value is defined in a profile of ISO 8601 and includes (among others) dates of the form YYYY-MM-DD. The nature or genre of the content of the resource. Type includes terms describing general categories, functions, genres, or aggregation levels for content. Recommended best practice is to select a value from a controlled vocabulary (for example, the DCMI Type Vocabulary). To describe the physical or digital manifestation of the resource, use the Format element. The physical or digital manifestation of the resource. Typically, Format will include the media-type or dimensions of the resource. Format may be used to identify the software, hardware, or other equipment needed to display or operate the resource. Examples of dimensions include size and duration. Recommended best practice is to select a value from a controlled vocabulary (for example, the list of Internet Media Types defining computer media formats). An unambiguous reference to the resource within a given context. Recommended best practice is to identify the resource by means of a string or number conforming to a formal identification system. Formal identification systems include but are not limited to the Uniform Resource Identifier (URI) (including the Uniform Resource Locator (URL)), the Digital Object Identifier (DOI), and the International Standard Book Number (ISBN). A Reference to a resource from which the present resource is derived. The present resource may be derived from the Source resource in whole or in part. Recommended best practice is to identify the referenced resource by means of a string or number conforming to a formal identification system. A language of the intellectual content of the resource. Recommended best practice is to use RFC 3066, which, in conjunction with ISO 639, defines two- and three-letter primary language tags with optional subtags. Examples include "en" or "eng" for English, "akk" for Akkadian, and "en-GB" for English used in the United Kingdom. A reference to a related resource. Recommended best practice is to identify the referenced resource by means of a string or number conforming to a formal identification system. The extent or scope of the content of the resource. Typically, Coverage will include spatial location (a place name or geographic coordinates), temporal period (a period label, date, or date range), or jurisdiction (such as a named administrative entity). Recommended best practice is to select a value from a controlled vocabulary (for example, the Thesaurus of Geographic Names [TGN]) and to use, where appropriate, named places or time periods in preference to numeric identifiers such as sets of coordinates or date ranges. Information about rights held in and over the resource. Typically, Rights will contain a rights management statement for the resource, or reference a service providing such information. Rights information often encompasses Intellectual Property Rights (IPR), Copyright, and various Property Rights. If the Rights element is absent, no assumptions may be made about any rights held in or over the resource. This group is included as a convenience for schema authors who need to refer to all the elements in the "http://purl.org/dc/elements/1.1/" namespace. This type definition is included as a convenience for schema authors who need a container element for all of the DC elements.
