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.

Mappings
Dublin Core
Depending on the direction of mapping necessary, check

- MODS to DC: http://www.loc.gov/standards/mods/mods-dcsimple.html
Note |
---|
Specific guidelines for mapping information from the DAMS MODS relatedItem element to the Dublin Core <dc:relation> element have not been finalized. |
MARC 21
See http://www.loc.gov/standards/mods/mods-mapping.html. The following specific guidelines apply for the DAMS:
MARC 21 field | Mapping condition | MODS element | Notes |
---|---|---|---|
590 | relatedItem[@type="host" and @displayLabel="Digital Collection"]/* | Check local note in MARC field 590 for information about Digital Collection. |
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 |
---|---|---|---|---|
relatedItem/identifier | mods_relatedItem_identifier | N/A | All relatedItem/identifier information is merged into a multivalued Solr field. | |
relatedItem[@type="host"]/identifier | mods_relatedItem_identifier_uri_host | N/A | All identifier information for relatedItem elements of type host is merged into a multivalued Solr field. | |
relatedItem/titleInfo/title | mods_relatedItem_titleInfo_title | N/A | All relatedItem/titleInfo/title information is merged into a multivalued Solr field. | |
relatedItem[@type="host"]/titleInfo/title | mods_relatedItem_titleInfo_title_host | N/A | All title information for relatedItem elements of type host is merged into a multivalued Solr field. | |
relatedItem/location/url | mods_relatedItem_location_url | N/A | All relatedItem/location/url information is merged into a multivalued Solr field. | |
relatedItem[@type="host" and @displayLabel="Digital collection"]/titleInfo/title | mods_host_related_resource_consolidated | mods_host_related_resource_consolidated | For display in the Collections portal, information from this element is combined with information from the relatedItem/location/url element. The respective type of information (in this case: Title) is added in parentheses. | |
relatedItem[@type="host" and @displayLabel="Digital collection"]/location/url | mods_host_related_resource_consolidated | mods_host_related_resource_consolidated | For display in the Collections portal, information from this element is combined with information from the relatedItem/titleInfo/title element.
