Abstract

MULTILINGUAL

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

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

Input guidelines: Input name and identifiers of a primary physical or digital collection context 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.

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.

Definition

Primary physical or digital collection the asset originated from. Distinct from Digital Collection.

Mappings

Dublin Core

Depending on the direction of mapping necessary, check

DC to MODS: https://www.loc.gov/standards/mods/dcsimple-mods.html
MODS to DC: http://www.loc.gov/standards/mods/mods-dcsimple.html

Dublin Core field	Mapping condition	MODS element	Notes
dc:source		relatedItem[@type="source" and @displayLabel="Source collection"]	MODS subelements are mapped into single dc:source element by concatenating the element values, separated by double dashes (--).

MARC 21

See http://www.loc.gov/standards/mods/mods-mapping.html#relateditem. The following specific guidelines apply for the DAMS:

MARC 21 field	Mapping condition	MODS element	Notes
590		relatedItem[@type="host" and @displayLabel="Source collection"]/*	Check local note in MARC field 590 for information about Source Collection.
79x		relatedItem[@type="host" and @displayLabel="Source collection"]/*	Check local added entries in MARC fields 790-799 for information about Source 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	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/titleInfo/title	mods_relatedItem_titleInfo_title	N/A	All relatedItem/titleInfo/title information is merged into a multivalued Solr field.
relatedItem[@type="source"]/titleInfo/title	mods_relatedItem_titleInfo_title_source	mods_relatedItem_titleInfo_title_source
