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
The following specific guidelines apply for the DAMS:
| Dublin Core field | Mapping condition | MODS element | Notes |
|---|---|---|---|
| dc:format | internetMediaType | Approximate mapping. Depending on the exact content, dc:format might also map to MODS elements extent or form. |
MARC 21
see https://www.loc.gov/standards/mods/mods-mapping.html#physicaldescription. The following specific guidelines apply for the DAMS:
| MARC 21 field | Mapping condition | MODS element | Notes |
|---|---|---|---|
| 347 | internetMediaType | Approximate mapping. The information given in MARC field 347 typically does not align with the list of expected file format values. The information can be used, however, to determine a resource's file type. | |
| 352$q | internetMediaType | Approximate mapping. The information given in MARC subfield 352$q typically does not align with the list of expected file format values. The information can be used, however, to determine a resource's file type. | |
| 856$q | internetMediaType | Approximate mapping. Check if the value given in MARC subfield 856$q aligns with the list of expected file format values for the DAMS. |
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 |
|---|---|---|---|---|
| physicalDescription/ internetMediaType | mods_type_consolidated_ms | mods_type_consolidated_ms | The value for file format is merged with metadata values for Genre and Type of Resource for display on the Collections portal (label "Type"). | |
| physicalDescription/ internetMediaType | mods_type_consolidated_ms | display_type_ms | The value for file format is merged with metadata values for Genre and Type of Resource for display on the Collections portal (label "Type"). The Solr field display_type_ms is generated from mods_type_consolidated_ms upon publishing, to feed the "Type" facet on the Collections portal start page. The first letter of each word is capitalized. |
