CHEK profiles

This repository defines profiles of standards used in the CHEK project.

It uses automated scripts to transform and validate implementation patterns into a semantic model that can be matched to the business rules. This transformation allows multiple forms of data to coexist (as required to integrate different systems) whilst simplifying using a single profile specification that meets this goal.

The high level architecture (and implementation status) is described in this workflow:

A canonical OWL representation of CityGML is the key blocker.

The "Topo-features" model for handling topological relationships in a manner compatible with OGC-API-Features has been prototyped in a related project and will be migrated to an OGC repository to support ongoing development, testing and reuse.

CityJSON uplift definition

The cityjson/ subdirectory hosts several CityJSON sample files and drafts for JSON Uplift Definitions that can be used to convert CityJSON into RDF.

The configuration for the uplift process is defined in .ogc/catalog.ttl.

A GitHub workflow updates the RDF versions of the JSON files on every push.
