Plain-language summary
HHM is shared so people can explore, test, and build on it. For now, we ask for kind attribution and hold a simple ethical line: please don’t use this work for military applications or in ways that harm human rights.
- Attribution: Please credit Cato Erga and link to harmonia.to when you use the model, code, figures, or text.
- Do no harm: No military use. No applications that violate human rights or intentionally cause physical or psychological harm.
- Non-commercial by default: Research, education, and personal projects are welcome. Please contact me for commercial use.
This keeps things fair while HHM is new. I plan to relax terms over time as the community grows.
The license (Hippocratic + Attribution Rider)
The text below adopts the spirit of the Hippocratic License (do-no-harm) with a short attribution rider. It’s simple to read; if you need a formal, lawyerly copy, reach out and I’ll share a notarized PDF version.
1) Permission
You are permitted to use, copy, modify, and share this work (the “HHM Materials”) for non-commercial, ethical purposes, provided you follow the terms below.
2) Required attribution
In any public or private use where the HHM Materials are used in analysis, figures, derivative code, or documentation, please include:
- “Holographic Harmonic Model (HHM) by Cato Erga — harmonia.to”
- A link to the HHM home page or the relevant DOI (when applicable)
This can be in an acknowledgments section, README, slide footnote, or methods paragraph — no need to be formal; just be clear.
3) Do No Harm
You may not use the HHM Materials to enable, support, or facilitate:
- Military, weapons, or combat applications
- Surveillance or targeting of individuals or groups
- Activities that violate the Universal Declaration of Human Rights or applicable human-rights law
- Applications intended to cause physical injury, psychological harm, or unlawful discrimination
4) Non-commercial use
Use is non-commercial by default. For commercial licensing (startups, products, paid services), please contact me.
5) Derivatives & sharing
- You may share derivatives and adapted works under these same terms (include this page or a link to it).
- If you add significant new research, feel free to release your additions under an additional license, as long as HHM portions keep this notice.
6) No warranty
The HHM Materials are provided “as is,” without warranty of any kind. Use at your own risk.
7) Term & future changes
These terms may be relaxed in the future to make sharing even easier. If that happens, I’ll keep a permalink to this version for anyone relying on it.
