Class Method Details

.library(record, location_map: Mappers.location) ⇒ Array<String>

Retrieves library location from enriched marc ‘itm’ or ‘hld’ fields, giving priority to the item location over the holdings location. Returns item’s location if available. Otherwise, returns holding’s location. Enriched maps enriched marc fields and subfields created during Alma publishing.

Parameters:

  • record (MARC::Record)
  • location_map (Hash) (defaults to: Mappers.location) —

    hash with location_code as key and location hash as value

Returns:

  • (Array<String>) —

    Array of library locations retrieved from location_map

end

.location(record:, display_value:, location_map:) ⇒ Array<String>

Base method to retrieve location data from enriched marc ‘itm’ or ‘hld’ fields, giving priority to the item location over the holdings location. Returns item location if available. Otherwise, returns holdings location. Enriched maps enriched marc fields and subfields created during Alma publishing.

Parameters:

  • record (MARC::Record)
  • display_value (Symbol, String) —

    field in location hash to retrieve

  • location_map (Hash) —

    hash with location_code as key and location hash as value

Returns:

  • (Array<String>)

.specific_location(record, location_map: Mappers.location) ⇒ Array<String>

Retrieves the specific location from enriched marc ‘itm’ or ‘hld’ fields, giving priority to the item location over the holdings location. Returns item library location if available. Otherwise, returns holdings library location. Enriched maps enriched marc fields and subfields created during Alma publishing.

Parameters:

  • record (MARC::Record)
  • location_map (Hash) (defaults to: Mappers.location) —

    hash with location_code as key and location hash as value

Returns:

  • (Array<String>) —

    Array of specific locations retrieved from location_map
