Dublin Core Metadata Element Set
What it is
The Dublin Core Metadata Element Set 1.1 is a vocabulary of fifteen broad, generic properties for describing many kinds of resources. The fetched 2012 reference is explicitly a historical snapshot; current documentation for these terms is part of the larger DCMI Metadata Terms specification.
Key concepts
- The fifteen elements are contributor, coverage, creator, date, description, format, identifier, language, publisher, relation, rights, source, subject, title, and type.
- The legacy
dc:properties have no formal domains or ranges so existing “simple Dublin Core” RDF implementations remain conformant. - Correspondingly named
dcterms:properties are subproperties of the legacy terms and add formal domains and ranges for machine-processable inference. - DCMI terms are designed to be combined with compatible vocabularies in application profiles.
How you’d use it
Attach a small, interoperable metadata record to a resource using the fifteen generic properties, applying controlled vocabularies or formal identifiers where the term guidance recommends them. Choose between the legacy dc: and dcterms: variants according to application requirements, while following DCMI’s encouragement to prefer the more semantically precise dcterms: properties over time.

Pitfalls & lessons
The page warns that this version is somewhat out of date and directs implementers to DCMI Metadata Terms for current documentation. The two namespaces are not interchangeable in semantics: dcterms: adds domains and ranges that the legacy dc: properties intentionally omit.
Verdict
A compact historical reference for the original fifteen Dublin Core properties; useful for legacy interpretation, while new work should consult the current DCMI terms and favor their more precise variants where appropriate.
