Rights and removal
The words on this site were written for it. Many of the pictures were not. This page says which is which, and gives anyone who owns something here a direct route to have it taken down.
If you own something here
Ask us to remove it and we will. You do not need to prove ownership, send a formal notice, or explain why. Naming the file or the page is enough.
- We aim to acknowledge within 3 working days and remove within 7.
- Removal is the default. We will not ask you to justify it.
- If you would rather have credit or a licence than removal, say so and we will do that instead.
That opens a short form on the project's GitHub repository. If you would rather not use GitHub, or the matter is sensitive, the repository profile has a direct contact for the project owner.
What is licensed for reuse, and what is not
The technique narrations, receiving notes, translations, syllabus transcriptions and all the underlying data are the project's own work and are published under CC BY-NC-SA 4.0: reuse them for non-commercial purposes, with credit, sharing what you build on under the same terms.
Teaching judo is not what that restriction is for. A club, a school or a coach may use this freely, including where they charge for lessons or membership. Selling the data, or a product built on it, is the part that needs asking, and the answer may well be yes: the project can grant a separate licence. The full position, and how to credit the project, is in the content repository.
The illustrations are not covered by that licence.The project cannot license what it does not own, so it does not try to. If you are reusing this reference, take the data and supply your own images.
Where the images came from
Every image on this site records its rights position, and these counts come straight from that data:
- 65 images: origin not established
- These come from a club reference document compiled over many years from many sources. The original sources were not recorded and cannot now be identified. They are published in good faith as a non-commercial teaching aid, marked honestly rather than passed off as ours, and removed on request.
- 33 images: known to belong to someone else
- Chiefly the Mon and Kyu syllabus sheets, which are federation publications reproduced so judoka can study their own syllabus, with the source named on the page. Credited to: Bill Nauta, Encino Judo Club (watermark on source image); British Judo Association; JudoScotland; judosport.net (watermark on source image). Permission has not been sought, and any of these rights holders can have their material removed by asking.
Replacing the uncertain images with purpose-made illustrations is an open goal. If you draw, that is the most useful contribution the project could receive.
Videos are linked, not copied
Demonstration videos are embedded or linked from the platform they were published on. Nothing is rehosted or downloaded: playback happens on the platform's own player, under its terms, with the view counting to whoever published it. If you would prefer your video not be linked from here at all, the same removal route applies and we will unlink it.
Names and organisations
Japanese technique names and their classification are facts and are claimed by nobody. Grading syllabuses are transcribed as published, with the source document named, because the list of what a grading requires is factual; the prose describing how to perform each technique is written for this project.
Waza Book is independent of the British Judo Association, JudoScotland, the Kodokan and the International Judo Federation, and is endorsed by none of them. Their names are used only to identify whose syllabus or material is being described.
