A new set of term declarations will be made available, and those new term declarations are summarized in this section. The terms described in this section are new*classes_ that are to be assigned URIs owned by DCMI. No changes to those term declarations are required. The terms described in this section are existing*classes_ that have already been assigned URIs owned by DCMI or by other agencies, and for which term declarations are already made available by their owners. ![]() Existing Classes Referenced in this Document **Figure 2 - the Classes associated with the Format property**Ģ.1. The relationships between the classes associated with the Format property and its subproperties are particularly complex and are shown in more detail in Figure 2: The relationships between the classes are summarized in the UML class diagram in Figure 1: This section describes a set of classes that are needed in order to describe has domain and has range relationships for DCMI properties. The DCAM relationship types has domain and has range are the same as the RDF Schema properties, rdfs:range and rdfs:domain. In practice, this means that the domain indicates the class of resources that the property should be used to describe, while the range indicates the class of resources that should be used as values for that property. Where it is stated that a property has such a relationship with a class and a described resource is related to a value by that property, it follows that the value is an instance of that class. Where it is stated that a property has such a relationship with a class and a described resource is related to a value by that property, it follows that the described resource is an instance of that class.Įach property may be related to one or more classes by a has range relationship. The relationship types with which this document is principally concerned are described by the DCAM as follows:Įach property may be related to one or more classes by a has domain relationship. This document uses the terminology of the DCMI Abstract Model.
