Sort features in a response.

Scope

Conformance Classes

Sorting implements the conformance class "Sorting" of the draft OGC API - Records - Part 1: Coreopen in new window.

Operations

ResourcePathMethodsMedia TypesDescription
Sortables
collections/{collectionId}/sortables
GET
The Sortables resource identifies the properties that can be referenced in the "sortby" parameter to order the features of the collection in the response to a query. The response is returned as a JSON Schema document that describes a single JSON object where each property is a sortable. Note that the Sortables schema does not specify a schema of any object that can be retrieved from the API. JSON Schema is used for the Sortables to have a consistent approach for describing schema information. JSON Schema is used in other parts of the API to describe schemas for JSON responses including in OpenAPI documents.

Query Parameters
