An announcement from The Open Geospatial Consortium (OGC) describes the publication of the OpenGIS Transducer Markup Language (TML) Implementation Specification as an approved OpenGIS Publicly Available Standard.
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. The OGC TML specification defines the conceptual model and XML Schema for describing transducers and supporting real-time streaming of data to and from sensor systems. TML thus defines (a) a set of models describing the response characteristics of a transducer, and (b) an efficient method for transporting sensor data and preparing it for use with other data through spatial and temporal associations.”
