The members of the Open Geospatial Consortium, Inc. (OGC) have approved Version 1.0 of the Transducer Markup Language Implementation Specification ("TML" or "TransducerML").
Sensor systems have two basic parts – a sensing element and a transducer that converts energy from one form to another form (usually an electric signal) that can be interpreted. TML defines the conceptual model and XML Schema for describing transducers and supporting real-time streaming of data to and from sensor systems. TML defines:
– A set of models describing the response characteristics of a transducer.
– An efficient method for transporting sensor data and preparing it for use with other data through spatial and temporal associations.
Along with other specifications coming out of the OGC’s Sensor Web Enablement activity, TML enables developers to create loosely coupled open systems for discovering, controlling and using Web-accessible sensors and transducers of all kinds, from simple digital switches to satellite-borne imaging systems.
