- **Upstream license:** GPL-3.0-or-later
- **Used descriptively in accordance with the OpenFOAM® Trademark Policy**
(https://www.openfoam.com/trademark-policy).
- Outram Park's `outram-foam-basic-lib`, `outram-foam-turbulence-lib`, and
`outram-foam-appbuilder-lib` crates are Rust translations of selected

- Outram Park's `outram-mc-libs` crate is a Rust translation of selected
OpenMC transport methods, ~~GPL-3.0~~ **AGPL-3.0-only** (relicensed 2026-10-20,
gh:#973) as permitted by the terms of the upstream MIT license. It is not an official OpenMC product and is not
sanctioned by MIT or Argonne National Laboratory.
### NJOY
- **Stewardship:** Los Alamos National Laboratory (LANL) and the
NJOY development team
- **Upstream URL:** https://www.njoy21.io (and https://github.com/njoy)
- **Upstream license:** BSD-style (see NJOY2016 LICENSE)
- Outram Park's `outram-park-njoy-fork` crate is a Rust translation of
selected NJOY nuclear data processing modules (RECONR, BROADR, ACER),
~~GPL-3.0~~ **AGPL-3.0-only** (relicensed 2026-10-20, gh:#973) as permitted
by the terms of the upstream BSD license. It is not an official NJOY product and is not sanctioned by

### CoolProp
- **Copyright:** Ian H. Bell and other CoolProp developers (2012-2018)
- **Upstream URL:** https://github.com/CoolProp/CoolProp
- **Upstream license:** MIT
- Outram Park's `outram-park-fork-coolprop` crate is a Rust translation of
selected CoolProp thermophysical-property methods (Helmholtz-energy-explicit
equations of state, incompressibles, mixtures, humid air),
~~GPL-3.0~~ **AGPL-3.0-only** (relicensed 2026-10-20, gh:#973) as permitted
by the terms of the upstream MIT license. It is not
an official CoolProp product and is not sanctioned by Ian H. Bell or the
CoolProp development team. Individual equations of state retain their own
original-author attribution where CoolProp itself documents one (e.g. the
IAPWS-95 formulation for Water: Wagner & Pruss, 2002) — see that crate's
`NOTICE` file.
### DWSIM
- **Trademark holder:** DWSIM Inc.
- **Copyright:** Daniel Medeiros and DWSIM contributors
- **Upstream URL:** https://dwsim.org
- **Upstream license:** GPL-3.0
- Outram Park's `outram-park-dwsim-fork` crate is a Rust translation of
selected DWSIM chemical process simulation methods. It is not an
official DWSIM product and is not sanctioned by DWSIM Inc. or its
contributors.
## Good-faith attribution commitment
Every source file in Outram Park that ports code from an upstream project
carries a header block naming:
- The upstream project and specific source file
- The upstream version or commit SHA
- The upstream copyright holder and license
- The upstream trademark (if any) and its holder
- An explicit non-affiliation notice
This documentary discipline is described in
`docs/CONTRIBUTING.md` and enforced during code review.
## Publication and citation
