List of Standards Working Groups

Members can access SWG sites by visiting Agora (Member Community).


If you would like to join a SWG but are not currently an OGC member, please get in touch.

PubSub SWG (PubSub SWG)

The purpose of the OGC PubSub SWG is to define an OGC Implementation Standard that enables publish/subscribe functionality for resources supported by OGC API Standards in a well-defined manner.

Routing SWG (Routing SWG)

The Routing SWG is chartered to develop and maintain an OGC API – Routes core standard and its extensions. Further, the SWG plans to publish and maintain a route exchange model.

SensorThings SWG (SensorThings)

The OGC SensorThings API provides an open and unified way to interconnect Internet of Things (IoT) devices, data, and applications over the Web. The OGC SensorThings API is an open Standard, and that means it is non-proprietary, platform-independent, and perpetual royalty-free.

Simple Features SWG (SF SWG)

The purpose of the ISO 19125 SWG is to update the common Standard that is both the OGC Simple Features Implementation Standard and the ISO 19125 Standards (Part 1: Common Architecture, and Part 2 SQL Option).

Styles and Symbology Encoding SWG (Styles SE SWG)

This working group defines a conceptual model and encodings for symbolizing digital Feature and Coverage data. It is also responsible for maintaining SLD/SE, an XML encoding for styles & symbology.

Temporal WKT for Calendars SWG (TemporalWKT)

The purpose of this SWG is to adapt a set of existing Standards to provide the capability to represent and encode temporal metadata within data sets and protocols which uses a customized calendar.

TimeSeriesML SWG (TimeSeriesML)

The purpose of this SWG is to manage and update the TimeSeriesML Standard. The work derived, in part, from WaterML 2.0 Part 1.

Training Data Markup Language for AI SWG (TrainingDML SWG)

The TrainingDML-AI SWG is chartered to develop the model and encodings for geospatial Machine Learning training data.
