There is no strong center of the IEEE 1451 web presence, but a google search on "IEEE 1451" finds many interesting and useful references. IEEE 1451 is a comprehensive, extremely detailed standard for describing sensors and actuators (together, "transducers"). From the web site:

A mature and active specification. The model is presented in several different forms (graphical, XML schema), with lots of documentation, and so should be useful to most developers.

The following description was taken from the web site on 2004.11.20.

Purpose: SensorML provides the models and XML schema encoding for defining the geometric, dynamic, and observational characteristics of a sensor. The purpose of SensorML is:

TML is a digital data structure that permits streaming and is used to exchange data between a sensor and a processor. TML is an XML based specification that describes how to capture and time tag sensor data. It also includes a complete description of the data. Since TML is self-contained, a TML enabled processor is able to process data from any sensor without any additional information.
