MODS Element	Attributes	Subelements
<mods:relatedItem>	@type	All MODS elements

Usage Guidelines

1. One <mods:relatedItem type=”host”>, with a title and link, is required in every record to identify the collection.
2. Any MODS element may be used as a subelement of <mods:relatedItem>, except nested <mods:relatedItem> elements.
4. <mods:relatedItem> may be used:
   • If you need to point to a record for a related item, using xlink and an empty element.
   • If you need to provide contextual information, such as a description of a series or version.
   • If you need to provide specific and detailed information about constituent parts, like the tracks on a CD.
5. The analog version of a digital surrogate should be described in the main record.
6. <mods:tableOfContents> is preferred over <mods:relatedItem>, unless more information is needed about constituent parts.
