OGC Members propose update to work of Features API Standards Working Group; public comment sought

The Open Geospatial Consortium (OGC) seeks public comment on the proposed updated charter for the Features API Standards Working Group (SWG). Comments are due by February 5, 2021.

The purpose of the Features API SWG is to: develop new and maintain existing parts of the OGC API - Features multipart standard; develop corrigenda for the related WFS 2.0 and FES 2.0 standards; and review draft Engineering Reports from the OGC Innovation Program related to OGC API - Features.

The recharter adds the following new work items to the SWG:

• Property selection - the ability to specify which feature properties should be presented in a response document.

• Geometry simplification - the ability to specify a resolution so that geometries are appropriately simplified (e.g., if you are zoomed out quite far, a polygon may be sufficiently represented as a point).

• Schema - will specify resources for various schemas related to a feature. For example: presentation schema - the properties that can appear in a response document; query schema - the properties that can be used to formulate query expressions, or; mutation schema - the schema of the feature that can be used to insert/update/delete features.

• Queries - specify new resources to handle long query expressions, multi-collection queries, and stored queries (with and without parameters).

OGC API - Features is a multi-part standard that offers the capability to create, modify, and query spatial data ‘features’ on the Web (features are simply the digital representations of objects of interest in the real world) and specifies requirements and recommendations for APIs that want to follow a standard way of sharing feature data.
