Mappings

Dublin Core

Currently, no data from <geographicCode> subelements is mapped to DC elements.

MARC 21

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

MARC 21 fieldMapping conditionMODS elementNotes
043$a
N/A

Do not map from MARC subfield 043$a.

MARC codes for geographic area are not implemented in the DAMS MODS.

043$c
subject/geographicCode

Data transformation required.

Map the Alpha-2 code from MARC subfield 043$c to the corresponding Alpha-3 code from the directory of ISO-3166 standard country codes.

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.
