OpenGIS Transducer Markup Language (TML) Encoding Specification

*THIS STANDARD HAS BEEN RETIRED* The OpenGIS® Transducer Markup Language Encoding Standard (TML) is an application and presentation layer communication protocol for exchanging live streaming or archived data to (i.e. control data) and/or sensor data from any sensor system. A sensor system can be one or more sensors, receivers, actuators, transmitters, and processes. A TML client can be capable of handling any TML enabled sensor system without prior knowledge of that system.

General Description

The goal of this Working Group is to clarify the role of time as a first-class alignment concept next to space, and to strive for a handling of time which is coherent and integrated with that of space. As the issue of time in CRSs is an overarching one across all OGC, the WG will seek to include background from as many OGC stakeholder groups and WGs as possible.



On 22 April 2015 the Open Geospatial Consortium (OGC®) issued a Request for Quotations/Call for Participation (RFQ/CFP) for the OGC Incident Management Information Sharing (IMIS) Internet of Things Pilot (IoT) Pilot – called IMIS IoT. This Pilot will prototype and demonstrate standards-based approaches to address a series of challenges that hinder effective use of large numbers of diverse sensors for use in emergency response and disaster response situations.
