Abstract
REPEATABLE
MODS Element name: <subject><cartographics>
Short definition: Cartographic (maps or charts) data indicating spatial coverage.
Input guidelines: Fill out all cartographic subelements or leave all blank. Use to record scale (e.g. 1:25,000), projection, and/or coordinates. You may record: "not drawn to scale", "scales differ", or "no projection statement" in these fields.
Do not enter scales for non-cartographic materials in this subelement.
Add scales for non-cartographic materials in a Note filed of type "scale" instead.
Definition
Cartographic (maps or charts) data indicating spatial coverage.
DAMS input form fields
Cartographics
| DAMS form field name | form field type | required | MODS element | Collections Portal display | notes |
|---|---|---|---|---|---|
| Coordinates | text field | no | subject/cartographics/coordinates | Cartographic Information | Contains a statement of coordinates covered by the resource. One or more statements may be supplied. Enter point coordinates in decimal format, with the value for latitude first (e.g.: 18.2975,-65.9914). Preferably, use positive values for coordinates on the Northern and Eastern hemisphere, and negative values for coordinates on the Southern and Western hemisphere. If you provide a compass direction, place it after the numeric coordinate, not before. Specifications for coordinates for bounding boxes (rectangles) or polygons have not yet been finalised. Please contact the DAMS Management team to coordinate a suitable representation for your geospatial data. Information from this field is consolidated with other cartographic subject information for display on the Collections portal. |
| Scale | text field | no | subject/cartographics/scale | Cartographic Information | Use this field to describe cartographic resources only. To record scale for non-cartographic resources, use the Note field with note type "scale". Information from this field is consolidated with other cartographic subject information for display on the Collections portal. |
| Coordinate/ spatial reference information | text field | no | subject/cartographics/projection | Cartographic Information | Information about the Coordinate or Spatial Reference System. For map content, typically a projection statement is available. You may also record: "no projection statement". In addition, this field can include information about coordinate system and datum, if available. Information from this field is consolidated with other cartographic subject information for display on the Collections portal. |
MODS Element description
Element <subject>
http://www.loc.gov/standards/mods/userguide/subject.html
Guidelines for use
<subject> is a container element that contains subelements relating to the subject aspect of the resource.
Attributes
No attributes are currently implemented in the DAMS for <subject> when used with the <cartographics> subelement.
Subelements
The following subelements of <subject> are used in the DAMS:
- cartographics
- (temporal)
- (topic)
- (geographic)
- (hierarchicalGeographic)
- (geographicCode)
Subelement <subject><cartographics>
Guidelines for use
<cartographics> is a container element; data content is entered in the subelements.
Fill out all <cartographics> subelements or leave all blank.
Attributes
Attribute name | Details | XPath syntax examples |
|---|---|---|
| displayLabel | value:
| subject/cartographics[@displayLabel="Cartographic properties"] |
Subelements
The following subelements of <subject><cartographics> are used in the DAMS:
- coordinates
- scale
- projection
Subelement <subject><cartographics><coordinates>
Guidelines for use
Contains a statement of coordinates covered by the resource. One or more statements may be supplied.
Enter point coordinates in decimal format, with the value for latitude first (e.g.: 18.2975,-65.9914). Preferably, use positive values for coordinates on the Northern and Eastern hemisphere, and negative values for coordinates on the Southern and Western hemisphere. If you provide a compass direction, place it after the numeric coordinate, not before.
Specifications for coordinates for bounding boxes (rectangles) or polygons have not yet been finalised. Please contact the DAMS Management team to coordinate a suitable representation for your geospatial data.

Subelements
No subelements for <coordinates>.
Subelement <subject><cartographics><scale>
Guidelines for use
Provides a statement of scale. Use this element to describe cartographic resources only. To record scale for non-cartographic resources, use the a note element with type "scale". You may also record: "not drawn to scale", or "scales differ".

Subelements
No subelements for <scale>.
Subelement <subject><cartographics><projection>
Guidelines for use
Information about the Coordinate or Spatial Reference System. For map content, typically a projection statement is available. You may also record: "no projection statement". In addition, this field can include information about coordinate system and datum, if available.

Mappings
Dublin Core
Currently, no data from <cartographics> subelements is mapped to DC elements.
MARC 21
See http://www.loc.gov/standards/mods/mods-mapping.html. The following specific guidelines apply for the DAMS:
| MARC 21 field | Mapping condition | MODS element | Notes |
|---|---|---|---|
| 500 | subject/cartographic/* | Use information in general notes (MARC field 500) for additional information about coordinates, zone, and equinox. | |
| 034$d$e$f$g | subject/cartographic/coordinates | Data transformation may be required. The target format for point coordinates in the DAMS MODS should be decimal, with the value for latitude first (e.g.: 18.2975,-65.9914). Preferably, use positive values for coordinates on the Northern and Eastern hemisphere, and negative values for coordinates on the Southern and Western hemisphere. If you provide a compass direction, place it after the numeric coordinate, not before. Specifications for coordinates for bounding boxes (rectangles) or polygons have not yet been finalised. Please contact the DAMS Management team to coordinate a suitable representation for your geospatial data. | |
| 255$c | subject/cartographic/coordinates | Data transformation required. The target format for point coordinates in the DAMS MODS should be decimal, with the value for latitude first (e.g.: 18.2975,-65.9914). Preferably, use positive values for coordinates on the Northern and Eastern hemisphere, and negative values for coordinates on the Southern and Western hemisphere.

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.
