RDFDublin Core Metadata Initiative
The Dublin Core Metadata Initiative (DCMI) has created predefined properties for describing documents.
Dublin Core
RDF is metadata (data about data). RDF is used to describe information resources.
The Dublin Core is a set of predefined properties for describing documents.
The first Dublin Core properties were defined in 1995 by the metadata working group in Dublin, Ohio, and are now maintained by the Dublin Core Metadata Initiative.
| Property | Definition |
|---|---|
| Contributor | An entity responsible for making contributions to the resource content (e.g., author). |
| Coverage | The extent or scope of the resource content. |
| Creator | An entity primarily responsible for creating the resource content. |
| Format | The physical or digital manifestation of the resource. |
| Date | A date associated with an event in the lifecycle of the resource. |
| Description | An account of the resource content. |
| Identifier | An unambiguous reference to the resource within a given context. |
| Language | The language used for the intellectual content of the resource. |
| Publisher | An entity responsible for making the resource content available. |
| Relation | A reference to a related resource. |
| Rights | Information about rights held in and over the resource. |
| Source | A reference to a resource from which the present resource is derived. |
| Subject | The topic of the resource content. |
| Title | A name given to the resource. |
| Type | The nature or genre of the resource content. |
By examining the table above, we can see that RDF is well-suited for representing Dublin Core information.
