OxiGAF: Licence and Sponsorship

What OxiGAF is

Gaussian avatar reconstruction in Pure Rust.

It is published on crates.io as oxigaf.

The licence in short

OxiGAF is source-available, not open source. Source-available means that you may read the source, copy it, change it and redistribute it with its licence attached. Until the Change Date it does not mean that you may run it in production, or publish software that depends on it, without a sponsorship.

The parts of OxiGAF are under these licences:

• Every crate of the repository (oxigaf and the oxigaf-* crates), with the documentation and the other files of the repository: Business Source License 1.1 (SPDX BUSL-1.1) until 2030-01-01, the Apache License, Version 2.0 from that day.

THIRD-PARTY-NOTICES.md lists what the repository and its packages redistribute that others wrote, with its origin and its licence.

The LICENSE file states these parameters:

The licence of a version released before OxiGAF 0.1.3 does not change. From the Change Date the Licensor grants the rights of the Apache License, Version 2.0 on every version released with that Change Date, and the limit on production use ends for them. Nothing has to be requested.

The LICENSE file shipped with each release governs. This page is a summary and the list of ways to sponsor. It changes the terms of no released version. Where this page and that file differ, the file is right.

The source repository is private. A release is the crates on crates.io and nothing else. Each package carries its source and the LICENSE file that applies to it, and each crate carries LICENSING.md, the plain-language summary for its version. The amounts, what needs a sponsorship and what is free are stated in those files, for that version, and this page does not change them.

What is free and what needs a sponsorship

Free. Non-production use needs no sponsorship, no registration and no key:

• evaluating the software, that is, trying it, on your own data and code too, in order to decide whether to adopt it;
• developing, building and testing the software itself;
• non-commercial research, academic research included, and teaching;
• non-commercial personal projects.

None of these covers publishing software that depends on the software. The Licensor regards that as production use, as the paragraphs below say.

Evaluation has no time limit. What ends it is adoption. Once the software is a dependency of software that is developed, distributed or operated commercially or in the course of business, or a standing part of how a business operates or of what it offers, the Licensor regards that use as production use and no longer as evaluation, whatever it is called.

Free on the Licensor’s own projects. Anyone may use the software without a sponsorship on a software project of the Licensor, in order to develop that project or to contribute to it. A software project of the Licensor is a software project that the Licensor publishes in its own repositories. Work on a copy of such a project that is done in order to contribute to it counts as work on that project. A fork that is maintained as a separate product is not such a project.

Unrestricted: what the software produces. The licence does not restrict the software’s output: the avatars, Gaussian splats, meshes, rendered images and trained parameters it produces, and the files it writes from them. That output may be used, changed and distributed for any purpose, production use included, with or without a sponsorship. Software that includes the software, or is built with it, is not its output. Material written by others that appears in output stays under its own licence.

Needs a sponsorship. Production use does. The Licensor regards any commercial use of the software as production use, that is, using it in the course of business: building it into software that is developed, distributed or operated commercially or otherwise in the course of business, whether as a Rust crate, through a package built from it for another language or as a program, and running it, or such software, to serve users or devices, to process data or to provide a service, for the business itself or for others. The Licensor regards a developer building such software on the software as part of the job as production use, and likewise a use inside a business that the business does not offer to others.

Publishing software that depends on the software. The Licensor also regards as production use publishing software that depends on the software, whether or not for a fee and whether or not that software is commercial. Software depends on the software when it names the software, or a package built from it, as a dependency, for example in its Cargo.toml. It is published when it, or its source, is made available to others, for example in a public repository on GitHub or another hosting service, or on crates.io or another package registry. This does not limit copying and redistributing the software itself with its licence attached, which the LICENSE file allows.

A sponsorship covers OxiGAF at any of three levels:

• USD 1,500 per month or more for OxiGAF alone. A sponsorship of that level for another of the Licensor’s works does not cover OxiGAF;
• USD 4,500 per month or more, with OxiGAF among at most five works that the Licensor licenses under the Business Source License and that the sponsor names to the Licensor in writing;
• USD 12,000 per month or more, which covers every work that the Licensor licenses under the Business Source License.

The sponsor is whoever uses the software: an organisation or an individual. An organisation’s sponsorship covers its employees, and the contractors working for it, when they use the software on its behalf. A sponsorship is active during each period for which its payment has been made. The right to production use that it gives lasts while the sponsorship is active and ends when it ends.

How to sponsor

There are four ways to take out a sponsorship that covers OxiGAF. They stand equal: use any one.

A sponsorship taken out in any way this page lists, and active, is a sponsorship in the sense of the Additional Use Grant in the LICENSE file. Which works it covers is as section 3 says. A card subscription of USD 1,500 taken out on this page is for OxiGAF. A card subscription of USD 4,500 is for the works named in the Works field of its checkout: naming them there is naming them to the Licensor in writing. To change them later, write to contact@cooljapan.tech.

This page can change. A sponsorship taken out in a way this page listed at the time remains one for as long as it is active, whatever the page lists later.

All the works under the Business Source License, and the ways to sponsor each, are on one page.

If none of these ways can be used, and other terms

If none of these ways can be used, write to the address below. An arrangement made with the Licensor in writing, at one of the levels of section 3 or above, counts the same as a sponsorship of that level taken out in one of those ways, and is for the works it names.

A commercial licence on other terms is asked for at the same address.

Practical notes

There is no licence key. OxiGAF does not ask for one and does not check for a sponsorship: the licence is kept on trust.

Payments by card are processed by Stripe. The checkout asks for the sponsor’s name, its billing address and a GitHub account: the account or organisation on GitHub under which the sponsor publishes software, so that the Licensor can match the sponsorship to it. A sponsor without one enters “none”. After paying, the checkout returns to a page that says what to do next.

A card subscription is managed in Stripe’s customer portal, billing.stripe.com, which signs you in with the e-mail address used at checkout: there you update the card or the billing details, find the invoices, or cancel. A cancellation takes effect at the end of the period already paid for.

So that a sponsorship can be matched to the organisation that uses OxiGAF, please sponsor from the organisation’s account, or write to contact@cooljapan.tech and name the organisation. This request only helps to match payments. Section 3 states who the sponsor is and whose use a sponsorship covers.

The Licensor, COOLJAPAN OÜ, is a company registered in Estonia (registry code 17287804). This is version 1.0 of this page.
