The governance model is a good question. The Apache model may work. The difference here is that it aims for a book. A book should has a clear author list, e.g. the rust book
by Steve Klabnik and Carol Nichols, with contributions from the Rust Community
I expect we can have 2-4 developers who spend a significantly amount of time on it to be the authors, and the authors will maintain the book (committer/PPMC in the Apache model). Similar to other D2L books, the book will be open to download and use, and authors may not receive remuneration to control the physical book price.
If there is a TVM org, it should be straightforward to have the repo to be part of the org. But we have a same problem as MXNet. It’s not a good idea to have the book source within the TVM source code repo. Hosting it under Apache may complicate the copyright issue, which needs to be resolved if printing the book. My current thought is moving the repo to the d2l-ai org once the legal review is finished. There are several other projects on-going for d2l-ai as well with collaborators among multiple universities and companies, it moves towards a neural organization.
