H2KG Ontology

Import Guide

EMMO-aligned ontology for hydrogen electrochemical systems, experiments, materials, measurements, and FAIR metadata

H2KG Ontology logoOntology release

Developed through DECODE, the Helmholtz Metadata Collaboration (HMC), and AIMWORKS to support FAIR ontology publication and reusable metadata infrastructure for hydrogen electrochemical systems.

Nested ODK Import Flow

Imports are refreshed through the nested ODK workbench and then surfaced through the AIMWORKS release pipeline.

  1. Open ontology_release/odk/src/ontology/.
  2. Run run.bat make refresh-imports.
  3. Review generated import modules under ontology_release/odk/src/ontology/imports/.
  4. Run the normal AIMWORKS release pipeline so the refreshed import status is copied into output/odk/ and reflected in the site.

Shadow Mode Context

ODK is currently operating in shadow mode. The AIMWORKS pipeline remains authoritative while ODK manages standard machine artefacts and import/QC infrastructure in parallel.

HDO role: HDO is the preferred Helmholtz-community source for data-management, metadata, identifier, digital-object, information-profile, schema, and validation concepts.

Current HDO-reviewed term count: 96
