Subelement <subject><hierarchicalGeographic>

Guidelines for use

<hierarchicalGeographic> is a wrapper element for the hierarchical form of place name. Use geographic name terms that are as specific as necessary or appropriate. First order political divisions may have different terms depending on the country. It is recommended to provide geographic terms that fall above the most specific term in the hierarchy (i.e. referring to larger geographic entities), to avoid ambiguity and to facilitate search and browsing.

In general, use the term(s) most commonly used in the original language or its translation for a geographic entity. Form fields in a fieldset must be input in the same language.

Attributes

No attributes for <hierarchicalGeographic> are currently implemented in the DAMS.

Subelements

The following subelements of <hierarchicalGeographic> are used in the DAMS:

• <country> Name of a country, i.e. a political entity considered a country.
• <region> Includes regions that have status as a jurisdiction, as well as regions incorporating more than one first level jurisdiction (e.g. Middle East).
• <state>Includes first order political divisions called states within a country, e.g. in U.S., Argentina, Italy. Use also for French départements.
• <territory> Name of a geographical area belonging to or under the jurisdiction of a governmental authority.
• <county> Name of the largest local administrative unit in various countries.
• <city> Name of an inhabited place incorporated as a city, town, etc.
• <citySection>Name of a smaller unit within a populated place, e.g., neighborhood, city or local park, street, street address, zip/postal code, census tract number, or district.
• <area>Names of non-jurisdictional geographic entities. Use area for continents, islands (a tract of land surrounded by water and smaller than a continent but not itself a separate country), and extraterrestrial areas (any extraterrestrial entity or space, including solar systems, galaxies, star systems, planets and geographic features of individual planets). Area may be used for terms that do not fit neatly into other designations in this hierarchy.

No attributes for the listed subelements of <hierarchicalGeographic> are currently implemented in the DAMS.

Mappings

Dublin Core

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

For mapping hierarchical geographic data, follow the DPLA Geographic and Temporal Guidelines (http://bit.ly/dpla-geo-styleguide). The guidelines recommend collapsing the data from subelements of each <hierarchicalGeographic> element to a single <dc:coverage> element, with values in ascending or descending order, separated by comma or semicolon.

MARC 21

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.
