## OTKO license
|
|
|
|
OTKO's own source code is licensed under the **GNU Affero General Public
|
|
License v3.0** (AGPL-3.0). The full text is in [`LICENSE`](LICENSE). This
|
|
`NOTICE` file does not replace or modify that license; where the two
|
|
disagree, `LICENSE` governs.
|
|
|
|
OTKO is **not** an MIT-licensed project. Portions of the codebase were
|
|
ported or adapted from an earlier, MIT-licensed prototype called
|
|
`otko-development`, so the original MIT notice is reproduced below as
|
|
required by that license.

## Ported / adapted code: `otko-development`

|

Portions of OTKO were ported or adapted from the `otko-development`
|
|
project, which is distributed under the MIT License. The MIT

## Runtime dependencies
|
|
|
|
OTKO depends on third-party software that is not covered by OTKO's
|
|
AGPL-3.0 license. Each component remains under its own license, and its
|
|
license text ships with the corresponding package. The notes below are a
|
|
summary for attribution, not a substitute for those license texts.
|
|
|
|
- **OpenSees / OpenSeesPy** — the finite-element solver invoked by
|
|
`otko.services.opensees_runner`. OpenSees is copyright The Regents of
|
|
the University of California and is distributed under a BSD-style
|
|
license; the notice is shipped inside the `openseespy` package.
|
|
- **PySide6** — the Qt 6 bindings used by the desktop GUI. PySide6 is
|
|
available under the GNU Lesser General Public License v3 (LGPLv3) or a
|
|
commercial license. OTKO links against it dynamically, which keeps the
|
|
LGPL relinking obligation satisfiable for redistributors.
|
|
- **numpy**, **pydantic**, **h5py**, **pyvista**, **VTK**,
|
|
**pyqtgraph**, and **imageio** — each is distributed under its own
|
|
license (for example BSD-3-Clause, MIT, and similar permissive terms).
|
|
See the license file bundled with each installed package for the exact
|
|
terms.
|
|
|
|
When redistributing OTKO, keep `LICENSE`, this `NOTICE`, and the license
|
|
notices of the dependencies above.
