FPWD Request for Semantic Sensor Network Ontology 2023 Edition - vocab-ssn-2023 from https://github.com/w3c/transitions/issues/728 # Document title, URLs, estimated publication date * **Title:** Semantic Sensor Network Ontology 2023 Edition * **URL:** https://www.w3.org/TR/vocab-ssn-2023/ * **Editors' draft:** https://w3c.github.io/sdw-sosa-ssn/ssn/ * **Publication date:** July 2025 Note: At this moment (9 July), the editors' draft is not ready. The title and the shortname still need to be changed to those given above. The lists of editors and contributors still need to be updated. And [pull request #334](https://github.com/w3c/sdw-sosa-ssn/pull/334), which rewrites appendix E, still needs to be merged. This transition request has been prepared in advance for the resulting draft. # Abstract The Semantic Sensor Network (SSN) ontology is an ontology for describing sensors and their observations, the involved procedures, the studied features of interest, the samples used to do so, and the observed properties, as well as actuators. SSN follows a horizontal and vertical modularization architecture, with the core classes and properties defined using minimal axiomatization in a graph called SOSA (Sensor, Observation, Sample, and Actuator) supplemented with additional axiomatization and terms in further graphs. These allow SSN 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. The namespace for the core terms is http://www.w3.org/ns/sosa/. The suggested prefix for the SOSA namespace is sosa. The SOSA graph containing the core definitions is available at http://www.w3.org/ns/sosa/. The SSN graph with the full axiomatization of the core terms is available at http://www.w3.org/ns/ssn/. # Status The status, see https://w3c.github.io/sdw-sosa-ssn/ssn/#sotd , is mostly standard, except for: > For OGC this is a Public Draft of a document prepared by the Spatial Data on the Web Working Group ([SDWWG](http://www.opengeospatial.org/projects/groups/sdwwg)) — a joint W3C-OGC project (see [charter](https://www.w3.org/2015/spatial/charter)). The document is prepared following W3C conventions. The document is released at this time to solicit public comment. > > This document was published by the [Spatio-temporal Data on the Web Working Group](https://www.w3.org/groups/wg/sdw) # Is it a delta specification intended to become a W3C Recommendation?
