Metadata Input Guidelines: Relation

Page Contents 9 minute read.

Element Name

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:
1. Relation type – drop-down menu
2. Relation – text field
Repeatable?
Yes - to include multiple relationships, click ‘Add’ to repeat all field parts

How Should the Relation Information 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 display note or non-display note instead
Guideline Example
  • Include the title of the related material
 Experiment Station Record Volume 61
  • Include a unique identifier or additional information if it is important to identify the item
    • If one item has multiple identifiers (e.g., a photograph with two images, each with a separate identifier), both can be included together
81-01796a-20_02 and 81-01796b-20_02
  • Include the permalink to the record of the related item
    • Since ARKs are only assigned after items are uploaded, some records may need to be edited at a later time to add permalinks
    • Note: When you paste an ARK into the relation field, the system will automatically make it a link in the record
ark:/67531/metapth38109
  • 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 (lower ARK)
  • 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)
