Ontology Development via GitHub¶

The CEON GitHub repository is the central platform for ontology development, versioning, and publication. The collaborative workflow established during Onto-DESIDE will continue to support future maintenance.

Workflow¶

flowchart LR
    A[Create feature\nbranch] --> B[Develop &\ncommit changes]
    B --> C[Open Pull\nRequest]
    C --> D[Review &\ndiscussion]
    D --> E[Merge to\nmain branch]
    E --> F[Auto-deploy\nvia GitHub Actions]

Key practices¶

Branching — development happens on feature branches, keeping the main branch stable
Commit messages — clear, descriptive messages document the history of progress
Pull Requests — formal proposals to merge changes, including summaries, diffs, and links to related issues
Issues — used to track bugs, tasks, and feature requests; can be assigned, labelled, and linked to PRs
Releases — new versions are published using GitHub's release tools, providing clear milestones and version history

Developer guidelines¶

Full developer guidelines are documented in the CEON README.

To support ongoing alignment and interoperability efforts, the Onto-DESIDE project compiled and documented a catalog of CE-related ontologies identified through a comprehensive literature study.

Focus domains¶

Domain	Topics
Circular Economy	Business models, resource recovery, waste, recycling, circularity assessment
Sustainability	Sustainability goals, performance, environment, energy
Materials	Raw materials, material composition
Logistics	Distribution, production, supply chain
Manufacturing	Manufacturing processes
Products	Product lifecycle

Ongoing monitoring¶

The catalog will continue to be maintained beyond the Onto-DESIDE project by regularly monitoring:

prefix.cc — ontology prefix registry where CEON is registered
LOV (Linked Open Vocabularies) — ontology registry where CEON is registered

The full catalog is available at: liusemweb.github.io/Circular-Economy-Ontology-Catalogue
