Quavsit Observatory
Quavern/quavsit-observatoryA daily record of 147 French public-transport feeds as an engine reads them: when each timetable ends, how old each real-time feed is, and how much of its real-time data matches the timetable. In trial since 15 September 2026; measurements under CC BY 4.0.

Licence
Quavern's repositories use the Quavern Open Source License, version 1.0 (QOSL-1.0). It is written to meet the Open Source Definition; it is not OSI-approved.
Quavern Open Source License 1.0
- Use, study, change and share the code for any purpose.
- A file of ours that you change stays under the licence when you distribute it or run it as a network service; the rest of your program stays yours.
- Patents held by contributors are licensed with their code.
- Credits to the producers of open data stay attached to the software.
The text of 15 September 2026 is a draft under legal review. This site's repository is its first use; if the review changes the text, the change gets a new version number.
How Quavern opens code
- What stays closed
- Code is opened where people need to inspect it, reuse it or trust it. Marl, Marl Code and the hosted Quavsit API stay closed: running them is the part customers pay for.
- Open data keeps its licence
- Open data keeps its licence and its credit: Licence Ouverte 2.0, ODbL, Licence Mobilités and the others named in each repository.
- No secret in a repository
- Provider keys, share links and personal details stay out of published code. A repository starts with its own history, never a copy of Quavern's private one.
- Security reports stay private
- Write to hello@quavern.com with "Security" in the subject, not in a public issue.
- Contributions
- Issues and pull requests are read. Each repository says what it accepts in its CONTRIBUTING file, and a contribution is received under the repository's licence.
