F.9 DC – Dublin Core
The Dublin Core schema is a small set of vocabulary terms that can be used to describe digital resources (video, images, web pages, etc.), as well as physical resources such as books or CDs, and objects like artworks.

Extract 1 – The DCMI Vocabulary Model
2.3 The DCMI Vocabulary Model
The abstract model of the vocabularies used in DC metadata descriptions is as follows:
- A vocabulary is a set of one or more terms. Each term is a member of one or more vocabularies.
- A term is a property (element), class, vocabulary encoding scheme, or syntax encoding scheme.
- Each property may be related to one or more classes by a has domain relationship. Where it is stated that a property has such a relationship with a class and the property is part of a property/value pair, it follows that the described resource is an instance of that class.
- Each property may be related to one or more classes by a has range relationship. Where it is stated that a property has such a relationship with a class and the property is part of a property/value pair, it follows that the value is an instance of that class.
- Each resource may be an instance of one or more classes.
- Each resource may be a member of one or more vocabulary encoding schemes.
Each class may be related to one or more other classes by a sub-class of relationship (where the two classes are defined such that all resources that are instances of the sub-class are also instances of the related class).
Each property may be related to one or more other properties by a sub-property of relationship. Where it is stated that such a relationship exists, the two properties are defined such that whenever the sub-property is part of a property/value pair describing a resource, it follows that the resource is also described using a second property/value pair made up of the property and the value.
Each syntax encoding scheme is a class (of literals).
Note that the word “vocabulary” is used here to refer specifically to a set of terms, a set in which the members are properties (elements), classes, vocabulary encoding schemes, and/or syntax encoding schemes.
