Definition: 

ExternalMaterial describes the location, structure, and relationship to the DDI metadata instance for any material held external to that instance. This includes citations to such material, an external reference to a URL (or other URI), and a statement about the relationship between the cited ExternalMaterial the contents of the DDI instance. It should be used as follows:as a target object from a relationship which clarifies its role within a class; or as the target of a relatedResource within an annotation.

Explanatory Notes: 

Within the DDI model, ExternalMaterial is used as an extension base for specific external materials found such as an External Aid. It is used as a base for specifically related material (e.g. ExternalAid) by creating a relationship whose name clarifies the purpose of the related material.

Example: 
ExternalMaterial is used to identify material and optionally specific sections of the material that have a relationship to a class. There is a generic relatedMaterial on AnnotatedIdentifiable. This should be used to attach any additional material that the user identifies as important to the class. The properties typeOfMaterial, descriptiveText, and relationshipDescription should be used to clarify the purpose and coverage of the related material.
