1. Introduction

This document uses the terminology of the DCMI Abstract Model [DCAM]. The relationship types with which this document is principally concerned are described by the DCAM as follows:

  • 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 a described resource is related to a value by that property, 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 a described resource is related to a value by that property, it follows that the value is an instance of that class.

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.

The DCAM relationship types has domain and has range are the same as the RDF Schema [RDFS] properties, rdfs:range and rdfs:domain.

2. Classes

This section describes a set of classes that are needed in order to describe has domain and has range relationships for DCMI properties.

The relationships between the classes are summarized in the UML class diagram in Figure 1:

Figure 1 - the Classes **Figure 1 - the Classes**

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:

3. Domain and Range assertions for DCMI Properties

This section summarizes the assertions to be made for has domain and has range relationships for existing DCMI properties.

3.1. Properties of the Dublin Core™ Metadata Element Set, Version 1.1.

The terms described in this section are existing*properties_ that have already been assigned URIs owned by DCMI, and for which term declarations are already made available by DCMI. No changes to those term declarations are required or proposed. No assertions of has domain or has range relationships will be made for the properties of the Dublin Core™ Metadata Element Set, Version 1.1. (This is equivalent to saying that for each of these properties there exists a has domain relationship with the class rdfs:Resource and a has range relationship with the class rdfs:Resource.)

3.2. Domain and Range assertions for the proposed new Properties of the Dublin Core™ Terms.

The terms described in this section are new*properties_ that are to be assigned URIs owned by DCMI. The URIs will be in the DCMI Namespace http://purl.org/dc/terms. A new set of term declarations will be made available, and those new term declarations are summarized in this section. Those term declarations include:

  • assertions of sub-property of relationships with other existing properties, and
  • assertions of has domain and/or has range relationships with one or more of the classes specified above

The human-readable label, definition, comment etc for these new properties will be the same as for the corresponding existing property of the Dublin Core™ Metadata Element Set, Version 1.1.

Note: for completeness, the tables below include has domain and/or has range relationships with the class rdfs:Resource (italicised in the tables). Such a relationship is implicit even in the absence of an explicit has domain or has range assertion, so those assertions will not be present in the term declarations.

3.3. Domain and Range assertions for the existing Properties of the Dublin Core™ Terms.

The terms described in this section are existing*properties_ that have already been assigned URIs owned by DCMI, and for which term declarations are already made available by DCMI. Some changes to those existing term declarations are proposed, namely the addition of:

  • assertions of sub-property of relationships with the new properties specified above, and
  • assertions of has domain and/or has range relationships with one or more of the classes specified above

Note: for completeness, the tables below include has domain and/or has range relationships with the class rdfs:Resource (italicised in the tables). Such a relationship is implicit even in the absence of an explicit has domain or has range assertion, so those assertions will not be present in the term declarations.

Note that the term declarations listed here also reflect the changes proposed in the document Revisions to DCMI Metadata Terms [REVTERM].
