Distinct from Source Digital Collection. Input guidelines: Input name , identifier, and/or URL of digital collections to which the asset belongs, such as those in other access systemsand identifiers of a primary physical or digital collection context from which the asset originated. If you enter information about a primary digital collection to which an asset belongs as Source Collection, do not duplicate this information here. Information about the DAMS parent collection of an asset is automatically added upon ingest. |

in the Digital Collection fields/elements. Recommended for digitized assets, especially those intended for public access. Collection names and identifiers should be as standardized as possible. Follow your unit/collection guidelines per Supervisor/Collection Owner. Enter URI, PID, and local identifiers when available.

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.
