The extension defines these fields in the Item object from OCDS:

Field Title Description Type(s)
deliveryLocation Delivery Location

The extension defines a new Location object with these fields:

Field Title Description Type(s)
description Description

A name or description of this location. This might include the name(s) of the location(s), or might provide a human readable description of the location to be covered. This description may be used in a user-interface.

geometry Geometry

We follow the GeoJSON standard to express basic location information, using longitude, latitude, and (optionally) elevation values in the WGS84 (EPSG:4326) projection. A point location can be identified by geocoding a delivery address. For concession licenses, or other contracts covering a polygon location which is not contained in a known gazetteer, polygon and multi-polygon can be used.

geometry.type Type

The type of GeoJSON Geometry Objects being provided. To provide longitude, latitude, and (optionally) elevation, use 'Point', and enter an array of [longitude, latitude] or [longitude, latitude, elevation] as the value of the coordinates field: e.g. [-122.085, 37.42]. Note the capitalization of type values, in order to maintain compatibility with GeoJSON.

string from closed geometryType codelist
geometry.coordinates Coordinates

The relevant array of points, e.g. [longitude, latitude] or [longitude, latitude, elevation], or a nested array of points, for the GeoJSON geometry being described. The longitude and latitude MUST be expressed in decimal degrees in the WGS84 (EPSG:4326) projection.

array of numbers / arrays
gazetteer Gazetteer

A gazetteer is a geographical index or directory. The specific gazetteer used should be specified in scheme, and one or more codes from that gazetteer used in identifier.

gazetteer.scheme Gazetteer scheme

The entry of the selected gazetteer in the gazetteers codelist. The codelist provides details of services, where available, that can resolve a gazetteer entry to provide location names.

string from open locationGazetteers codelist
gazetteer.identifiers Identifiers

An array of one or more codes drawn from the gazetteer indicated in scheme.

array of strings
uri URI

A URI to a further description of the activity location. This may be a human readable document with information on the location, or a machine-readable description of the location.
