JMap Server can connect to services complying with the OGC API Features standard (<https://ogcapi.ogc.org/features/>) to use them as spatial data source.&#x20;

{% hint style="info" %}
This new OGC standard replaces the WFS services standard.

OGC API Features provides APIs for creating, modifying, and querying “features” (real world elements or entities) on the web.&#x20;

The OGC API Features is made up of several parts, each of which is a separate standard.&#x20;

Part 1, the “core”, specifies the basic capabilities and is limited to the recovery of features where the geometries are represented in the WGS 84 longitude/latitude coordinate reference system.&#x20;

Part 2 specifies capabilities for extracting features whose geometries are represented in all other coordinate reference systems.&#x20;

Part 3, which is in the development phase, concerns data filtering as well as queries using the Common Query Language (CQL).&#x20;

Additional capabilities that meet more advanced needs will be specified in additional parts: support for creating and modifying features, more complex data models, multiple data sets, and collection hierarchies (<https://www.ogc.org/standards/ogcapi-features>).

JMap Server implements part 1 of the standard, which provides access to spatial data (entities or features) organized in collections. The data is sent in HTML or GeoJSON format (<https://ogcapi.ogc.org/features/overview.html>).
