5 November 2012 – The Open Geospatial Consortium (OGC®) seekspublic comment on the candidate OGC SensorML 2.0 Encoding Standard.

SensorML is a machine-readable language for describingsensors, actuators, and processes surrounding measurement. SensorML is a keycomponent of the OGC SensorWeb Enablement (SWE) suite of standards. 

SensorML 2.0 includes the following changes to the previousversion 1.0.1, which was approved in 2007:

  •  Separation of SWE Common Data as a separate standard
  •  More tightly defined rules
  •  Conformance classes allowing for incremental support ofSensorML in software and derived encodings
  •  A host of examples provided at initial release of thespecification.

In addition, SensorML 2.0 includes the following new orimproved features:

  •  Support for property extension using external schema
  •  Better-defined support for positions and dynamic state(e.g. location, orientation, velocity, and acceleration)
  •  Better support for inheritance allowing for compactdescriptions of deployed devices and processes
  •  Direct access to real-time values and data streams
  •  Better support for multiplexed data streaming (i.e.streams with disparate messages).

SensorML 2.0 supports the descriptions of things within theInternet of Things (IoT) and Web of Things (WoT) by providing a common standardfor sensors (“things the measure”), actuators (“things thatact”), and processors (“things that calculate”). Efforts arealso underway to take advantage of the complementary role that SensorML 2.0 canplay with the OGC City Geography Markup Language (CityGML) Encoding Standardand the candidate OGC standard IndoorGML.

The OGC SensorML 2.0 Encoding Standard Evaluation Package isfree and can be downloaded from http://www.opengeospatial.org/standards/requests/93.The deadline for comments is 5 December 2012.

The OGC is an international consortium of more than 465companies, government agencies, research organizations, and universitiesparticipating in a consensus process to develop publicly available geospatialstandards. OGC Standards support interoperable solutions that”geo-enable” the Web, wireless and location-based services, andmainstream IT. OGC Standards empower technology developers to make geospatialinformation and services accessible and useful with any application that needsto be geospatially enabled.
