Contransus™ Translation Project

The "Contransus" (源译识) Translation Project, initiated by the OpenAtom Foundation, aims to build open source consensus via translation, in the hope of developing a widerly-shared open source ecosystem. This project is launched to promote better understanding of open source by offering professionally-reviewed, publicly available and community-oriented translations of various open source resources, primarily into Chinese. The project focuses on not only translation of open-source licenses, but also of open-source-related judgments, books, key reports, etc.

Through the Project Repository, you are warmly welcome to participate in the Contransus Project by using approved translations, filing your translation, sharing your opinion on any translation texts, as well as recommending useful resources and expert in open source domain.

Translations of Open Source License

The open source license section are open to community for contributions and discussions. Aiming to provide a permanent and reliable Chinese translation of open-source licenses that is accessible to everyone, we established a Review Panel of experts in regard to both open source and languages, including Professor ZHOU Minghui (leading professor of OSI-approved Mulan PSLv2, etc.), WEI Sir (translator of OS licenses), SHEN Fen (top open source legal counsel from Huawei and a recognized legal expert in OS community), Professor SONG Lei (the chief editor of the English-Chinese Dictionary of Law Terms), and Professor XU Meiling (assistant professor from UIBE). The panel has been working collaboratively in reviewing and revising candidate translation texts line by line to develop a finalized version of translation.
