SSN
General information
Abstract
SSN follows a horizontal and vertical modularization architecture by including a lightweight but self-contained core ontology called SOSA (Sensor, Observation, Sample, and Actuator) for its elementary classes and properties.
Description
This ontology describes sensors, actuators and observations, and related concepts. It does not describe domain concepts, time, locations, etc. these are intended to be included from other ontologies via OWL imports.

Projects and usage information
Known usage
With their different scope and different degrees of axiomatization, SSN and SOSA are able to support a wide range of applications and use cases, including satellite imagery, large-scale scientific monitoring, industrial and household infrastructures, social sensing, citizen science, observation-driven ontology engineering, and the Web of Things.

Community
Audience
The initial SSN was developed with ontology engineers in mind as the primary audience. Due to the widespread adoption of SSN, the increasing role of citizen science, the strong focus on lightweight vocabularies by the Linked Data community, and vocabularies such as Schema.org, the ontology was streamlined. The new SSN introduces additional classes and relations on top of SOSA to model the capabilities of sensors and actuators, the compositionality of systems, and so forth to suit more complex needs or cases in which more provenance data is required, e.g., to improve reproducibility.Repository

Notes
The SSN ontology adds formal axiomatization consistent with the text definitions in SOSA, and adds classes and properties to accommodate the scope of the original SSN ontology. , Please report any errors to the W3C Spatial Data on the Web Working Group via the SDW WG Public List public-sdw-wg@w3.orgContent
