# Third-Party Notices `@silurus/ooxml` is MIT-licensed (see [LICENSE](./LICENSE)). It bundles the third-party components listed below, none of which are copyleft. This file is included in the npm tarball so it travels with every install. ## JavaScript / bundled asset ### Natural Earth Admin 0 Countries, 1:110m The optional Region Map renderer contains a coordinate-quantized derivative of Natural Earth's Admin 0 Countries 1:110m vector dataset. Natural Earth states that all versions of its raster and vector data are in the public domain. The generated source records the exact upstream SHA-256 and fixed feature/vertex bounds. The boundaries are illustrative, show Natural Earth's default de-facto point of view, and do not imply this project's endorsement of any territorial claim. - Source: - Terms: ### MathJax + STIX Two Math (`mathjax-stix2.js`) The optional equation-rendering engine (`@silurus/ooxml/math`, opt-in — see the [README's "Rendering equations" section](./README.md#rendering-equations)) pre-bundles two Apache-2.0 packages into a single ~3 MB asset (`packages/core/assets/mathjax-stix2.js`, built by [`packages/core/build/build-mathjax.mjs`](./packages/core/build/build-mathjax.mjs)). It ships in the npm tarball but is only fetched by a consuming app at runtime if that app imports `@silurus/ooxml/math` **and** the loaded document actually contains an equation. - **[MathJax](https://www.mathjax.org/)** (`@mathjax/src`, v4.1.2) — Copyright © MathJax Consortium. Licensed under the [Apache License, Version 2.0](#apache-license-20-full-text). - **STIX Two Math font, as packaged for MathJax v4** (`@mathjax/mathjax-stix2-font`, v4.1.2) — Copyright © MathJax Consortium. The npm package declares `"license": "Apache-2.0"` in its `package.json` (verified by reading `node_modules/@mathjax/mathjax-stix2-font/package.json` directly; the package does not bundle its own `LICENSE` file, so this is the authoritative declaration). Licensed under the [Apache License, Version 2.0](#apache-license-20-full-text). Note: the STIX Two Math font is also separately distributed upstream () under the SIL Open Font License 1.1. The build in this repository consumes the Apache-2.0-licensed `@mathjax/mathjax-stix2-font` npm package specifically, not the upstream OFL font files directly, so Apache-2.0 is the governing license for the bytes actually shipped here. Neither package includes a Apache-2.0 §4(d) `NOTICE` file (checked in the installed `node_modules` tree), so there is no additional NOTICE content to reproduce beyond the attribution above. ### Build-time only (not shipped) The library also declares `esbuild` (MIT) as a build-time dependency (bundles `mathjax-stix2.js` above) and TypeScript (Apache-2.0) as a dev/type-check dependency. Neither's code is included in the published package — noted here for completeness only. ## Rust / WebAssembly The three parser crates (`docx-parser`, `pptx-parser`, `xlsx-parser`) and their shared `ooxml-common` crate compile to the `*_parser_bg.wasm` binaries shipped in `dist/`. Their `wasm32-unknown-unknown` dependency graph is identical across all three crates (verified with `cargo license --filter-platform wasm32-unknown-unknown`) and consists entirely of permissively-licensed crates — no copyleft (GPL/LGPL/AGPL) dependencies: | License | Crates | |---|---| | MIT OR Apache-2.0 | bumpalo, cfg-if, console_error_panic_hook, crc32fast, displaydoc, equivalent, flate2, hashbrown, indexmap, itoa, log, once_cell, proc-macro2, quote, roxmltree, rustversion, serde, serde_core, serde_derive, serde_json, syn, thiserror, thiserror-impl, wasm-bindgen, wasm-bindgen-macro, wasm-bindgen-macro-support, wasm-bindgen-shared | | (Apache-2.0 OR MIT) AND Unicode-3.0 | unicode-ident | | 0BSD OR Apache-2.0 OR MIT | adler2 | | Apache-2.0 | zopfli | | Apache-2.0 OR MIT OR Zlib | miniz_oxide | | MIT | simd-adler32, zip, zmij | | MIT OR Unlicense | memchr | Full license texts for each crate are available from [crates.io](https://crates.io/) or the crate's own repository; SPDX identifiers above match each crate's `Cargo.toml` `license` field. This list was generated with: ```bash cargo install cargo-license cargo license --manifest-path packages/pptx/parser/Cargo.toml \ --avoid-dev-deps --filter-platform wasm32-unknown-unknown # docx-parser / xlsx-parser produce an identical dependency set ``` ### MCP server (`ooxml-mcp-server`, separate distribution) `packages/mcp-server` is not part of the `@silurus/ooxml` npm package — it is a standalone binary distributed independently (see the repository's MCP server documentation). Its dependency graph is a superset of the table above (adds `tokio`, `rmcp`, `anyhow`, `schemars`, `tracing`, and their transitive deps for the async runtime and MCP protocol implementation) and remains entirely MIT / Apache-2.0, with no copyleft licenses: ```bash cargo license --manifest-path packages/mcp-server/Cargo.toml --avoid-dev-deps ``` ## Unicode Character Database data The line-breaking, vertical-orientation and Arabic-shaping logic is driven by tables generated from the Unicode Character Database (UCD), © Unicode, Inc., licensed under the [Unicode License v3](#unicode-license-v3-full-text) (SPDX: `Unicode-3.0`), which expressly permits copying, modification and redistribution of the data files with this notice. Checked into this repository (generator inputs, each retaining its original Unicode copyright header; not part of the npm tarball): - `packages/core/scripts/VerticalOrientation.txt` (UAX #50 Vertical_Orientation, UCD 17.0.0) - `packages/docx/scripts/ArabicShaping.txt` (Joining_Type / Joining_Group, UCD 17.0.0) - `packages/docx/scripts/DerivedJoiningType.txt` (UCD 17.0.0) Shipped in `dist/` as UCD-derived data compiled from the above and from `LineBreak.txt` / `DerivedGeneralCategory.txt` / `EastAsianWidth.txt` (fetched at generation time, not checked in): the `*.generated.ts` tables under `packages/core/src/text/` and `packages/docx/src/` (line-break classes, East Asian width, vertical orientation, bidi character data, Arabic joining classes). The `unicode-ident` Rust crate listed above also carries `Unicode-3.0` in its SPDX expression for the same reason (embedded UCD-derived tables). ## License texts - **MIT** — see [LICENSE](./LICENSE) (this repository's own license; the MIT-licensed dependencies above use the same standard text with their own copyright holder). - **Unicode License v3** — canonical text at , reproduced below. - **Apache License, Version 2.0** — full text at , reproduced below for convenience. ### Unicode License v3 (full text) ``` UNICODE LICENSE V3 COPYRIGHT AND PERMISSION NOTICE Copyright © 1991-2026 Unicode, Inc.
