Abstract
REPEATABLE MULTILINGUAL
MODS Element name: <subject><temporal>
Short definition: The time period, date, or date range the content of the resource is about.
Input guidelines: Temporal Coverage may be expressed as a controlled subject term or as a structured date. Enter a named time period (Elizabethan), date (YYYY-MM-DD), or date range (YYYY/YYYY, YYYY-YYYY, YYYY to YYYY). Recommended authorities are AAT, LCSH and PeriodO. Input dates in structured format YYYY-MM-DD. If only part of a date is known, enter year and month only (YYYY-MM) or year only (YYYY). To record time intervals, preferably append a forward slash ('/') to the start date of the interval, followed by the end date of the interval, without spaces between dates and separator (example: 2012-05-29/2012-05-31).
Definition
The time period, date, or date range the content of the resource is about.

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 |
