Omega-X Ontology Repository

Welcome to the Omega-X Ontology repository!

Repository Structure

The repository structure is built to fit multi-level modular ontologies. It hosts also relevant alignements to external resources (ontologies/standards).

The tooling section includes automation scripts for various tasks: ontology building, documentation release, semantic validation, data semantization...

The omega-X ontology is defined by two modules: a core ontology for Events and Time Series (ETS) and a domain ontology for Energy Data Set (EDS).
