MODS Element name: <relatedItem type="source" displayLabel="Source collection" usage="primary">

Short definition: Physical or digital collection the asset originated from. Distinct from Digital Collection.

Input guidelines: Input name and identifiers of a physical or digital collection from which the asset originated. If you enter information about a primary digital collection as Source Collection, do not duplicate this information 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.

Note

The title entered for Source Collection is used to generate a search facet in the Collections portal.

Use consistent spelling for the Source Collection Title, as spelling variants or typos will result in separate facets being generated.

Source Collection information is not required, but it is highly recommended to enter at least the title of a Source Collection. Consider supplying a collection name to facilitate browsing if now established collection name exists. Information in this field/element is currently the only structured information allowing to browse assets by their collection context in the Collections portal.

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.
