Label Access Rights
URI https://opengeometadata.org/ogm-aardvark/#access-rights
Field Name dct_accessRights_s
Field Type String
Obligation Required
Multivalued False
Purpose To clarify to the user if the resource is public (any user can access) or restricted (a user will need to log in to some kind of authentication protocol) and if the application should provide a web service preview and/or a download function.
Entry Guidelines Only one of two values are allowed: Public or Restricted.
Commentary This field can be set to "Public", which allows users to view and download an item, or "Restricted", which requires a user to log in to an authentication service.
Controlled Vocabulary Yes - strict
Example Value "Public"
Element Set DCMI

Alternative Title

Label Alternative Title
URI https://opengeometadata.org/ogm-aardvark/#alternative-title
Field Name dct_alternative_sm
Field Type Array of strings
Obligation Optional
Multivalued True
Purpose To provide the user with the another title if needed.
Entry Guidelines This could be for a secondary or original title or subtitle.
Commentary For discoverability, improving titles for data is encouraged. This field could be a place to keep the original title. It could also be useful for scanned maps. Some have long titles that include MARC subtitle fields, such as 245$b. Whether or not this field should appear in your GeoBlacklight item view pages can be customized in the application.
Controlled Vocabulary No
Example Value ["NEZ H Districts"]

Bounding Box

Label Bounding Box
URI https://opengeometadata.org/ogm-aardvark/#bounding-box
Field Name dcat_bbox
Field Type String
Obligation Suggested
Multivalued False
Purpose To support overlap ratio boosting in spatial searches.
Entry Guidelines This should be a bounding box in this format: ENVELOPE(W,E,N,S).
Commentary If the Geometry field uses the ENVELOPE syntax, then these fields will be identical.
Controlled Vocabulary No
Example Value "ENVELOPE(-111.1, -104.0, 45.0, 40.9)"
Element Set DCAT
Group Spatial

Centroid

Label Centroid
URI https://opengeometadata.org/ogm-aardvark/#centroid
Field Name dcat_centroid
Field Type String
Obligation Optional
Multivalued False
Purpose To display the centerpoint of a resource.
Entry Guidelines Enter two decimal degree coordinates separated by a comma in this order: latitude, longitude.
Commentary This field is currently only supported by customizations to the GeoBlacklight application.
Controlled Vocabulary No
Example Value "46.4218,-94.087"
Element Set DCAT
Group Spatial

Creator

Label Creator
URI https://opengeometadata.org/ogm-aardvark/#creator
Field Name dct_creator_sm
Field Type Array of strings
Obligation Suggested
Multivalued True
Purpose To credit the person/organization that collected or authored the resource.
Entry Guidelines The suggested controlled vocabulary is the Library of Congress Name Authority File.
Commentary The distinction between Creator and Publisher is often vague. This field is best reserved for instances in which an individual person has collected, produced, or generated analyses of data (as opposed to an agency releasing a data product or resource). It can be a person or an organization.
Controlled Vocabulary No
Example Value ["Geological Survey (U.S.)"]
Element Set DCMI
Group Credits

Date Issued

Label Date Issued
URI https://opengeometadata.org/ogm-aardvark/#date-issued
Field Name dct_issued_s
Field Type String
Obligation Optional
Multivalued False
Purpose To provide the user with the date when an item was published, and to allow administrators to determine the age of the resource.
Entry Guidelines A single year is the preferred format. For more precise dates, use the ISO format without the time value: YYYY-MM-DD or YYYY-MM.
Commentary Although the field is optional, it is often useful when a clear Temporal Coverage value is not present. For example, one may want to preserve a dataset with an uncertain lineage, but there is an indicator on a data portal on the date of last update. In most cases, the 4-digit year is sufficient.
Controlled Vocabulary No
Example Value "1999"
Element Set DCMI
Group Temporal

Date Range

Label Date Range
URI https://opengeometadata.org/ogm-aardvark/#date-range
Field Name gbl_dateRange_drsim
Field Type String
Obligation Optional
Multivalued True
Purpose To power other time widgets that use a date range.
Entry Guidelines Enter a start date and end date in the Solr date range field convention. In JSON, the value should be formatted as a string that includes the brackets, rather than as an array or list containing a string. Incorrect: ["YYYY TO YYYY"]. Correct: "[YYYY TO YYYY]".
Commentary This field is not yet supported by GeoBlacklight, but the application can be customized to use it.
Controlled Vocabulary No
Example Value "[1980 TO 1995]"
Element Set GBL
Group Temporal

Description

Label Description
URI https://opengeometadata.org/ogm-aardvark/#description
Field Name dct_description_sm
Field Type Array of strings
Obligation Suggested
Multivalued True
Purpose To provide the user with a summary of the resource.
Entry Guidelines At a minimum, this is a reiteration of the title in sentence format. Other relevant information, such as data creation methods, data sources, and special licenses, may also be included.
Commentary This field is the second-most prominent value (after Title) that users see when search or browsing for items. Although not required, it is strongly recommended. If the description is minimal or lacking, it can be improved by concatenating available metadata fields, such as title, date, format, and place. This is a plain text field by default, but it can include clickable links if the GeoBlacklight software is customized; see the GeoBlacklight documentation on how to render HTML from a text field.
Controlled Vocabulary No
Example Value "This polygon shapefile represents boundaries of election districts in New York City. It was harvested from the NYC Open Data Portal."
Element Set DCMI
Group Descriptive

Field Name gbl_displayNote_sm
Field Type Array of strings
Obligation Optional
Multivalued True
Purpose To highlight additional information about a resource, such as warnings or tips for using the data.
Entry Guidelines Prefix the string with "Danger:", "Info:", "Tip:", or "Warning:" to specify the type of note.
Commentary Starting in GeoBlacklight version 4.1, text in this field is prominently displayed in a shaded box just after the title, with the prefixes controlling the style of the displayed note. Styles and additional prefixes (for example, in other languages) can be added by customizing the GeoBlacklight software; see the v4.1.0 release notes.
Controlled Vocabulary No
Example Value ["Danger: This text will be displayed in a red box","Info: This text will be displayed in a blue box","Tip: This text will be displayed in a green box","Warning: This text will be displayed in a yellow box","This is text without a tag and it will be assigned the default 'note' style"]

Geometry

Label Geometry
URI https://opengeometadata.org/ogm-aardvark/#geometry
Field Name locn_geometry
Field Type String
Obligation Suggested
Multivalued False
Purpose To display the extent of the resource and to power the map search.
Entry Guidelines This may be a bounding box or more complex geometry. For a bounding box, it should use the ENVELOPE(W,E,N,S) syntax. For a more complex geometry, it should use the WKT ("well-known text") POLYGON or MULTIPOLYGON syntax. Note that WKT polygon vertices should be defined in counter-clockwise order.
Commentary Since this field is not repeatable, multiple polygons should be represented using the WKT "MULTIPOLYGON" syntax. Geometries that span the 180th meridian, aka the antimeridian, should be broken up into multiple bounding boxes or polygons for each side of the earth's hemisphere. This is because Solr, the underlying indexer for GeoBlacklight, cannot interpret these coordinates correctly and will display the geometry improperly (horizontally flipped).
Controlled Vocabulary No
Example Value Simple bounding box: "ENVELOPE(-111.1, -104.0, 45.0, 40.9)" | Bermuda Triangle: "POLYGON((-80 25, -65 18, -64 33, -80 25))" | Split bounding box for Alaska: "MULTIPOLYGON (((-179.3 51.1, -129.9 51.1, -129.9 71.5, -179.3 71.5, -179.3 51.1)),((172.3 51.2, 179.9 51.2, 179.9 53.1, 172.3 53.1, 172.3 51.2)))"

Georeferenced

Label Georeferenced
URI https://opengeometadata.org/ogm-aardvark/#georeferenced
Field Name gbl_georeferenced_b
Field Type Boolean or string
Obligation Optional
Multivalued False
Purpose To indicate whether or not a scanned map or other imagery has a georeferenced version.
Entry Guidelines Only one of two values are allowed: true or false.
Commentary This field can be a shortcut for users to find georeferenced maps. Administrators can also employ the Source field to link a paper map with its scan (e.g. a TIFF) and its georeferenced version (e.g. a GeoTIFF).
Controlled Vocabulary Yes - strict
Example Value false or "false"

ID

Label ID
URI https://opengeometadata.org/ogm-aardvark/#id
Field Name id
Field Type String
Obligation Required
Multivalued False
Purpose To provide a unique alpha-numeric ID for the item that will act as the primary key in Solr and to create a unique landing page for the item.
Entry Guidelines Enter a string of alpha-numeric characters separated by dashes. The ID must be globally unique across all institutions in your GeoBlacklight index.
Commentary This field makes up the URL for the resource in GeoBlacklight. It is visible to the user and is used to create permalinks. If having a readable slug is desired, it is common to use the form institution-keyword1-keyword2.
Controlled Vocabulary No
Example Value "princeton-rv042w38t"

Label Index Year
URI https://opengeometadata.org/ogm-aardvark/#index-year
Field Name gbl_indexYear_im
Field Type Array of integers
Obligation Suggested
Multivalued True
Purpose To power the "Year" facet and time slider widgets that rely on integers for dates.
Entry Guidelines Enter one or more 4-digit integers.
Commentary Ideally this field should describe the date(s) depicted in a resource. Because it powers the "Year" facet, it is one of the key ways users can find items by their date.
