The Open Geospatial Consortium (OGC) seeks public comment on a revision to the joint ISO and OGC Standard, Observations and Measurements (O&M). 

The O&M Standard defines a conceptual schema for observations, including for features involved in the observation process, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities.

O&M enables other Standards and specifications for capturing information originating from sensors as well as various environmental prediction models, using shared semantic concepts. Application areas can be as diverse as scientific devices capturing water and air quality measures, to cameras on drones, to tracking devices on commercial transport.

The O&M standard arose from work originally undertaken through OGC’s Sensor Web Enablement (SWE) activity. A set of interfaces and protocols was standardized, through which applications and services are able to access sensors of all types, and observations generated by them, over the Web. O&M now forms the foundation for a number of other OGC Standards, such as TimeseriesML and GroundwaterML.

A new generation of geospatial standards is now emerging, based on general Web standards, architecture, and current practice, as described in the W3C/OGC Spatial Data on the Web Best Practices and exemplified by the OGC API family of standards. This includes several new standards for describing and publishing sensors and observations, such as OGC SensorThings API and W3C/OGC Semantic Sensor Network Ontology. This new version of the O&M Standard is informed by these recent developments and is aimed at enabling the publication of observation data as part of the Web of Data, while also supporting other means of data exchange.
