License

The short version

The original prose on this site is available for personal study and short quotation with attribution. Republishing pages in full requires permission. Material that is not original to this site is covered by its own terms.

What is covered

The text written for this site - the pages under sections like the Ubigraph pillar, the demos, the docs, the papers companion notes, and the lab notes - is original to this site unless a passage is clearly marked as a quotation.

Original text on the site is licensed for the following uses without asking:

• Reading on the site itself.
• Linking to a page from anywhere.
• Quoting short passages, with attribution to the page URL.
• Citing pages in a paper, a blog post, or a write-up.
• Saving pages for offline personal study.

Anything beyond that needs a short message through the contact page.

What is not covered

Some material on the site is not original and is not covered by the licence above:

• PDF files at the historical paper paths. These are reference texts. Where a verified original is served, the terms of the original apply. Where a placeholder PDF is served, the placeholder itself is original to this site, but you should not treat it as a stand-in for the original paper.
• Logos, brand marks, and small visual identifiers used on the site.
• External resources reached through links from the site.

If you want to reuse one of these, you need to identify the actual source and consult the terms that apply to it.

Attribution

When you quote or cite the original prose, a normal academic-style attribution is enough. The page URL and the site name are sufficient. There is no required wording beyond that.

If you are citing a specific claim, please cite the specific page rather than the homepage.

Translations

If you want to translate a page on this site for personal study or for a small reading group, that is acceptable without asking. If you want to publish a translation more widely, the contact page is the route to ask first.

Translations that are republished elsewhere should make clear they are translations of the original, and should link back to the original page.

Republishing in full

Republishing a full page on another property is not allowed without permission. There are two practical reasons.

1. Pages on this site are revised. A copy of a page elsewhere will drift out of date.
2. Pages are written carefully and republishing in full undermines the editorial choices that went into them.

If there is a strong reason to republish in full, the contact page is the route to discuss it.

Code samples

Short code samples in the documentation pages are intended to be illustrative and are free for reuse without attribution. They are written to teach a pattern, not as production-ready code. Use them at your own discretion.

If a sample grows into something substantial enough to be considered a separate work, that will be noted on the page where it appears.

Commercial use

Short quotation with attribution is fine in a commercial context. Wider use of the original prose in a commercial product needs permission. The contact page is the route to ask.

Warranties

The site is provided as-is. The license above grants permission to use the content under the listed terms. It does not include any warranty about correctness, completeness, or fitness for any particular purpose.

If you rely on a specific claim on the site for a decision that matters, verify it against an independent source.

Final note

The intent of this license is to keep the prose useful for readers while preventing the kind of bulk republishing that would make the site less useful over time. If your use sits in a grey area, it is usually faster to ask than to guess.
