This is the repository for the Spatial Data on the Web Working Group, a collaborative project between W3C and OGC.
The repo has been used for developing editors drafts of the Working Group's deliverables and related resources.
The Working Group follows in the footsteps of the Spatial Data on the Web Interest Group and the Spatial Data on the Web Working Group, and some of the material in this repository was initially developed and published by these predecessors.
Work on a new edition of the Semantic Sensor Network (SSN) Ontology is recorded in a separate repository: https://github.com/w3c/sdw-sosa-ssn. The editor's draft is available at https://w3c.github.io/sdw-sosa-ssn/ssn/.
The new edition adds many of the terms from ssn-extensions into the core SSN Ontology, as well as functionality from the 2023 Revision of ISO 19156 - Observations, Measurements and Samples (available freely as OGC Abstract Specification - Topic 20).

This folder is no longer used actively. It contains the state of things as they were left after SOSA/SSN was published by the Spatial Data on the Web Working Group in October 2017. Development of The Semantic Sensor Network Ontology Recommendation continues in a separate Github repository "sdw-sosa-ssn".
Editor's Draft
W3C Recommendation - time-aggregates
-
Extension to the Time Ontology in OWL defining a class for temporal aggregates.
Editor's Draft
W3C Interest Group Note - time-entity-relations
-
Extension to the Time Ontology in OWL defining additional relations between time intervals.
Editor's Draft
W3C Interest Group Note - time
-
The Time Ontology in OWL Recommendation initially developed by the Spatial Data on the Web Working Group.
