Spatial Data on the Web Working Group

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.

SSN New Edition

Work on a new edition of the Semantic Sensor Network (SSN) Ontology is in a separate repo: https://github.com/w3c/sdw-sosa-ssn.
