Spatial Data on the Web Working Group

The Semantic Sensor Network Ontology (commonly known as "SSN" is an ontology for describing sensors and the observations they make of the physical world. SSN is published in a modular architecture that supports the judicious use of "just enough" ontology for diverse applications, including satellite imagery, large scale scientific monitoring, industrial and household infrastructure, citizen observers, and Web of Things.

This specification defines WebVMT, the Web Video Map Tracks format, which is an enabling technology whose main use is for marking up external metadata track resources in connection with the HTML element. WebVMT files provide map presentation, annotation and interpolation synchronized to web media content, and more generally any form of data that is time-aligned with audio or video content, including those from location-aware devices such as dashcams, drones and smartphones.

This document shows how dense geospatial raster data can be represented using the W3C RDF Data Cube ontology in concert with other popular ontologies. SPARQL queries can then be served through an OGC Discrete Global Grid System for observations, coupled with a triple store for observational metadata.

Spatial Data on the Web Working Group

An extension to the RDF Data Cube ontology to support specification of key metadata required to interpret spatio-temporal data. QB4ST provides generalized support for numeric and other ordered references systems, particularly Spatial Reference Systems and Temporal Reference Systems.

This Note describes CoverageJSON, a data format for describing "coverage" data in JavaScript Object Notation (JSON), and provides an overview of its design and capabilities. The primary intended purpose of the format is to enable data transfer between servers and web browsers, to support the development of interactive, data-driven web applications.

Spatial Data on the Web Working Group

This document describes use cases that demand a combination of geospatial and non-geospatial data sources and techniques. It underpins the collaborative work of the Spatial Data on the Web Working Groups operated by both W3C and OGC.

Latest Candidate Recommendation Snapshot

26 March 2020

OWL-Time is an OWL-2 DL ontology of temporal concepts, for describing the temporal properties of resources in the world or described in Web pages. The ontology provides a vocabulary for expressing facts about topological (ordering) relations among instants and intervals, together with information about durations, and about temporal position including date-time information. Time positions and durations may be expressed using either the conventional (Gregorian) calendar and clock, or using another temporal reference system such as Unix-time, geologic time, or different calendars.

Spatial Data on the Web Working Group

This document advises on best practices related to the publication and usage of spatial data on the Web; the use of Web technologies as they may be applied to location. The best practices are intended for practitioners, including Web developers and geospatial experts, and are compiled based on evidence of real-world application.
