| <h2>Introduction</h2> | ||
|
|
||
| <p> | ||
| Sensors are a major source of data available on the Web today. | ||
| However, searching, reusing, integrating, and interpreting sensor data requires more than just the sensing results. | ||
| For the proper interpretation of these values, knowledge of the feature of interest, such as a river, the observed | ||
| property, such as flow velocity, the sampling strategy, such as the specific locations and | ||
| times at which the velocity was measured, and a variety of other information are required. | ||
| </p> | ||
| <p> | ||
| OGC's Sensor Web Enablement standards [[SWE]], [[SensorML]], [[OandM]], [[OMS]], [[STA]] provide | ||
| conceptual models, as well as some encodings for the annotation of sensors and their observations. | ||
| [[OMS]] provides a comprehensive description of the characteristics of observations and samples. | ||
| Integration and alignment of these with W3C Semantic Web technologies and Linked Data embeds this in a global and | ||
| densely interconnected graph of data. | ||
| </p> | ||
| <p> | ||
| With the rise of the Web of Things and smart cities and homes more generally, actuators and the data they produce | ||
| also become first-class citizens of the Web. | ||
| Given their close relation to sensors and observations, it is desirable to provide an ontology that also includes | ||
| actuators and actuation. | ||
| </p> | ||
| <p> | ||
| Finally, with the increasing diversity of data and data providers, definitions for sensors need to be broadened, to | ||
| include human agents and social sensing. | ||
| </p> | ||
| <p> | ||
| This specification defines the Semantic Sensor Network (<b>SSN</b>) ontology. | ||
| It sets out to provide flexible but coherent perspectives for representing the entities, relations, and activities | ||
| involved in sensing, sampling, and actuation. | ||
| A lightweight core for SSN, known as <b>SOSA</b> (Sensor, Observation, Sample, and Actuator) aims at broadening the | ||
| target audience and application areas that do not need the full capabilities of Semantic Web ontologies. | ||
| SOSA acts as minimal interoperability fall-back level, i.e., it defines terms (classes and properties) with which | ||
| data can be safely exchanged across all uses of SSN, its modules, and SOSA. | ||
| </p> | ||
| <p> | ||
| The previous edition of the SSN Ontology [[vocab-ssn-20171019]] harmonised earlier work from OGC ([[OandM]]) and W3C | ||
| ([[SSNX]]) . | ||
| A new edition of the OGC/ISO standard [[[OMS]]] has updated [[[OandM]]] with a number of additional features arising | ||
| from more than 10 years implementation experience. | ||
| <b>This new edition of the SSN Ontology is primarily intended to align with OMS, so that SSN may serve as the | ||
| canonical RDF implementation of OMS.</b> | ||
| </p> | ||
| <p> | ||
| In addition, developments in <em>Internet of Things</em> implementations have contributed some ideas particularly | ||
| around actuation. | ||
| Finally, direct experience with SSN has uncovered a variety of more minor issues that have been addressed or | ||
| accommodated. | ||

| This change log describes the changes since the 2017 edition [[vocab-ssn-20171019]]. | ||
| For earlier changes during the development of the SSN Ontology, please consult Annex "D. Change History" in | ||
| [[vocab-ssn-20171019]]. | ||

| An <a href="#origins">Annex to this document</a> provides a brief account of the origins of the SSN ontology through | ||
| various OGC and W3C initiatives. | ||
