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. 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. The OGC API Features is made up of several parts, each of which is a separate standard. 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. Part 2 specifies capabilities for extracting features whose geometries are represented in all other coordinate reference systems. Part 3, which is in the development phase, concerns data filtering as well as queries using the Common Query Language (CQL). 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 7 Kathmandu 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>).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.k2geospatial.com/en2/administrator/jmap-server-administrator-manual/spatial-data-sources/vector-data-sources/ogc-api-features.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
