Abstract
Repeatable
MODS Element name: <relatedItem type="host" displayLabel="Digital collection">
Short definition: Digital collection/s in the DAMS or other access systems to which the asset belongs. Distinct from Source Collection.
Input guidelines: Input name, identifier, and/or URL of digital collections to which the asset belongs, such as those in other access systems. If you enter information about a collection to which an asset belongs as Source Collection, do not duplicate this information here.

Dublin Core field | Mapping condition | MODS element | Notes |

Solr
In general, all MODS metadata is imported into the DAMS Solr server upon ingest. The ingest process generates Solr fields typically named according to the following schema:
mods_value*_suffix
where
value* can be one or multiple element, subelement or attribute names that allow to distinguish Solr fields
suffix is s, t, ss, ms or mt, which refers to the type of data stored in a Solr field and how it is indexed. The Solr index usually contains multiple copies of each field with the same content, distinguished by their suffix.
The following table shows mappings between MODS elements and Solr fields for those fields that are currently used for display in the Collections portal, or where additional processing happens in Islandora or during the publishing process. Suffixes are ignored, unless relevant for the mapping.
MODS element | Mapping condition | Solr DAMS | Solr Collections Portal | Notes |
|---|---|---|---|---|
