Relation
Definition
Information about another resource that is related to the current resource.
Where Can the Relation Information be Found?
Relation information provides a reference to a related resource which may be found on:
a title page
accompanying or supplementary information
How Relation Works in the Metadata Form
- Parts:
Relation type – drop-down menu
Relation – text field
- Repeatable?
Yes - to include multiple relationships, click ‘Add’ to repeat all field parts
- Required?
No (more information)
How Should the Relation be Filled in?
Enter information about known relationships in the records for both items
It is not necessary to do research to find related resources
If the relationship is unclear, uncertain, or otherwise questionable, the information may be entered into a note instead

Choose the appropriate relation qualifier from the controlled vocabulary
Generally both halves of the reciprocal relation should be represented so that each record references the other
In some cases, if there are a large number of related items on one side (usually has part/is part of), the child items should all reference the parent, but the reciprocal may be eliminated
The direction of the relationship should reflect which of the items was created first or is a more original version
If you cannot determine which is the more original/first created item, default to the one uploaded first (first ARK, sequentially)
If more than one qualifier applies (e.g., transcription and translation), choose one and explain as needed in a display note
If none of the qualifiers applies to the items, the qualifier can be left blank, but consider whether the information might be more appropriate in another field such as:

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.
Items may also have other content-based connections that are not represented best by a formal “Relation.” For example, materials may have topical, geographic, or temporal relationships represented in the Date, Coverage, Subject, or other appropriate fields.
Relationships are drawn primarily from Dublin Core Metadata Initiative (DCMI) standards (a full list of fields and controlled vocabulary terms can be accessed here.
The relationships for transcription and translation are locally added
We include “Conforms To” within our controlled vocabulary as a DCMI relationship, but it is not currently used within the system.
Local practice is to use the Relation field specifically for reciprocal references between items in the Digital Collections, rather than describing relationships between an item in the Digital Collections and an external resource.
Although only the ARK is technically required to establish a relationship, it is highly encouraged to include a title or other identifying information for clarity and to increase metadata shareability (e.g., for harvesting)
