This document provides an overview of Dublin Core including its basic principles, vocabularies, namespaces, and elements. It discusses Dublin Core applications like CONTENTdm and DSpace, and provides examples and documentation resources for implementing Dublin Core metadata.
![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].”

![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.”

![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).

![Type
Label: Type
Definition: 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.

![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].

- 2. Applications Using Dublin Core • CONTENTdm • DSpace • Omeka • OAI-PMH Harvesting (Open Archives Initiative Protocol for Metadata Harvesting) • RDF
- 3. Basic Principles • Everything is optional, and everything is repeatable! • Is extensible – vocabularies and linked data
- 4. 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
- 5. 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/
- 6. 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/
- 7. 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). http://dublincore.org/documents/dc-xml-guidelines/
