Markkit
Copyright 2024-2026 Everruns

Licensed under the MIT License.

=== Design Inspirations ===

Markkit is an independent implementation. The following projects
inspired aspects of its design:

* Readability (Apache 2.0) – Mozilla's approach to content extraction
  informed our HTML-to-markdown pipeline design.

* Pandoc (GPL-2.0) – The universal document converter's format
  coverage and conversion philosophy inspired our multi-format
  architecture.

* turndown (MIT) – The JavaScript HTML-to-markdown converter's
  rule-based approach influenced our conversion engine design.

Markkit's parser, converter, and extraction pipeline are original
Rust implementations. This project is not affiliated with, endorsed
by, or derived from any of the above projects.

=== Key Dependencies ===

Markkit relies on permissively licensed crates, including:

* scraper (ISC), html5ever (MIT/Apache-2.0) – HTML parsing
* zip (MIT), quick-xml (MIT), calamine (MIT), cfb (MIT) – Office document containers and XML
* hayro-syntax / hayro (MIT/Apache-2.0) – PDF parsing and page rendering
* ocrs, rten (MIT/Apache-2.0) – optional Rust OCR backend
* reqwest (MIT/Apache-2.0), rustls (Apache-2.0/ISC/MIT) – optional HTTP client
* tokio (MIT) – async runtime
* serde / serde_json (MIT/Apache-2.0) – serialization
* pyo3 (MIT/Apache-2.0), napi (MIT), wasm-bindgen (MIT/Apache-2.0) – bindings

The allowed license set is enforced by `cargo deny check licenses` (deny.toml).
Binary packages (CLI, Python wheels, Node native addon, WebAssembly) statically
link these crates; their license texts and copyright notices are in each
crate's source on crates.io, pinned by Cargo.lock. cssparser and selectors
(via scraper) are MPL-2.0; their unmodified source is available from crates.io.

=== Bundled Third-Party Data ===

The `pdf-ocr` feature renders PDF pages with hayro, which compiles the
following data into the binary. It is enabled in the CLI, the Python package
and the native Node package (not in the default crate build or WebAssembly).

=== Not Bundled ===

OCR model weights (CC-BY-SA 4.0), Tesseract and its language data are not
included in any markkit package. `just ocr-models` downloads the pinned models
and writes their license and attribution to target/ocr-models/NOTICE.json.

=== Public Benchmark Tooling ===

scripts/public_benchmarks/vendor includes the Mira Python SDK (Everruns, MIT),
the AgentDocBench scorer (SylphxAI, MIT), and the WCXB scorer (Murrough Foley,
CC-BY-4.0), each with its license. Input documents retain the individual
licenses and attribution in scripts/public_benchmarks/CORPUS-NOTICE and
agentdocbench-corpus.json. The downloaded corpora are not included in packages.
