Abstract

REPEATABLE MULTILINGUAL

MODS Element name: <physicalDescription><form>

Short definition: A designation of a particular physical presentation of a resource, including the physical form or medium of material for a resource.

Input guidelines: Characterize the form of the digitized or analog original using terms describing the material, support, or technique. Use authority control, e.g. AAT, TGM, LCGFT or locally controlled vocabularies. This field/element set is not used to describe the content of a resource. Use the Genre and/or Type of Resource elements to describe the content of the resource. If you do not use a controlled vocabulary, check the Type facet on the Collections portal to avoid spelling variants for uncontrolled terms.

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.

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.
