How Should the Relation Information be Filled in?

To show that the item has a different format	Is format of / Has format
To show that the item is part of a larger resource	Is part of / Has part

To show that an item is intellectually interrelated	References / Is referenced by
To show that a later version overrides an earlier one	Replaces / Is replaced by
To show that an item needs another component	Requires / Is required by
To show that an item is compliant with a set of standards**	Conforms to

Comments

• To make observations about related subject matter in the intellectual content of another resource (for example, photographs of the same storm-damaged building taken from different viewpoints), use the Note element.
• Relationships are drawn primarily from Dublin Core Metadata Initiative (DCMI) standards (a full list of fields and controlled vocabulary terms can be accessed here). 
  

**We include "Conforms To" within our controlled vocabulary as a DCMI relationship, but it is not currently used within the system.
