Observations and Measurements (O&M) is an International
Standard which defines a conceptual schema encoding for observations, and for
features involved in sampling when making observations. While the O&M
standard was developed in the context of geographic information systems, the
model is derived from generic patterns proposed by Fowler and Odell, and is not
limited to spatial information. O&M is one of the core standards in the OGC
Sensor Web Enablement suite, providing the response model for Sensor
Observation Service (SOS).
