Applications Using Dublin Core
• CONTENTdm• DSpace• Omeka• OAI-PMH Harvesting (Open Archives
Initiative Protocol for Metadata Harvesting)• RDF
Basic Principles• Everything is optional, and everything is
repeatable!• Is extensible – vocabularies and linked
data
Vocabularies• “The terms in DCMI vocabularies are
intended to be used in combination with terms from other, compatible vocabularies in the context of application profiles and on the basis of the DCMI Abstract Model [DCAM].”
http://dublincore.org/documents/dces/#DCTERMS
Namespaces• “All changes made to terms of the Dublin Core
Metadata Element Set since 2001 have been reviewed by a DCMI Usage Board in the context of a DCMI Namespace Policy [DCMI-NAMESPACE]. The namespace policy describes how DCMI terms are assigned Uniform Resource Identifiers (URIs) and sets limits on the range of editorial changes that may allowably be made to the labels, definitions, and usage comments associated with existing DCMI terms.”
http://dublincore.org/documents/dces/
Dumb Down Principle• “According to this rule, a client should be
able to ignore any qualifier and use the value as if it were unqualified. While this may result in some loss of specificity, the remaining term value (minus the qualifier) must continue to be generally correct and useful for discovery. Qualification is therefore supposed only to refine, not extend the semantic scope of an Element.”
http://dublincore.org/documents/dces/
Qualified Dublin Core• 5.1 Abstract model• A qualified DC record is made up of one or more properties and their
associated values.• Each property is an attribute of the resource being described.• Each property must be either:
– one of the 15 DC elements,– one of the other elements recommended by the DCMI (e.g. audience) [DCTERMS],– one of the element refinements listed in the DCMI Metadata Terms recommendation
[DCTERMS].• Properties may be repeated.• Each value is a literal string.• Each value may have an associated encoding scheme.• Each encoding scheme has a name.• Each literal string value may have an associated language (e.g. en-GB).

Dublin Core Metadata Element Set
• contributor• coverage• creator• date• description• format• identifier• language
• publisher• relation• rights• source• subject• title• type
DCMI Metadata Terms (excluding Element Set, i.e. Qualifiers)
• abstract• accessRights• alternative• available• bibliographicCitation• conformsTo• created• dateAccepted
• dateCopyrighted• dateSubmitted• extent• hasFormat• hasPart• hasVersion
Qualifiers cont.• isFormatOf• isPartOf• isReferencedBy• isReplacedBy• isRequiredBy• issued• isVersionOf• license• medium
• modified• references• replaces• requires• spatial• tableOfContents• temporal• valid
Additional DCMI Metadata Terms (not Element Set)
• Audience– educationLevel– Mediator
• Agent– rightsHolder
• Domain– accrualMethod– accrualPeriodicity– accrualPolicy
• Range– instructionalMethod– Provenance
Relation--Qualifiers• conformsTo• hasFormat• hasPart• hasVersion• isFormatOf• isPartOf• isReferenceBy
• isReplacedBy• isRequiredBy• isVersionOf• references• replaces• requires• source
Source
Label: Source
Definition: A related resource from which the described resource is derived.
Comment:
The described resource may be derived from the related resource in whole or in part. Recommended best practice is to identify the related resource by means of a string conforming to a formal identification system.
Type
Label: TypeDefinition: The nature or genre of the resource.
Comment:
Recommended best practice is to use a controlled vocabulary such as the DCMI Type Vocabulary [DCMITYPE]. To describe the file format, physical medium, or dimensions of the resource, use the Format element.
References: [DCMITYPE] http://dublincore.org/documents/dcmi-type-vocabulary/#H7
Format
Label: Format
Definition: The file format, physical medium, or dimensions of the resource.
Comment: Examples of dimensions include size and duration. Recommended best practice is to use a controlled vocabulary such as the list of Internet Media Types [MIME].

CONTENTdm Example
Vocabulary Encoding Schemes - example
Term Name: DCMIType URI: http://purl.org/dc/terms/DCMIType Label: DCMI Type Vocabulary
Definition: The set of classes specified by the DCMI Type Vocabulary, used to categorize the nature or genre of the resource.
See: http://purl.org/dc/dcmitype/
Type of Term: http://purl.org/dc/dcam/VocabularyEncodingScheme
Version: http://dublincore.org/usage/terms/history/#DCMIType-005
Syntax Encoding Scheme - example
Term Name: ISO639-2 URI: http://purl.org/dc/terms/ISO639-2 Label: ISO 639-2
Definition: The three-letter alphabetic codes listed in ISO639-2 for the representation of names of languages.
See: http://lcweb.loc.gov/standards/iso639-2/langhome.html
Type of Term: Datatype Version: http://dublincore.org/usage/terms/histor

Class - exampleTerm Name: SizeOrDuration URI: http://purl.org/dc/terms/SizeOrDuration Label: Size or Duration
Definition: A dimension or extent, or a time taken to play or execute.
Comment: Examples include a number of pages, a specification of length, width, and breadth, or a period in hours, minutes, and seconds.
