HAMON — Licensing
=================

Copyright (c) 2026 Universidad de Alicante.

The software was written by Patricia Garcia-Iasci and David Rizo. The standard
and the ICCCM'26 paper it accompanies are the work of Patricia Garcia-Iasci,
Johannes Hentschel, Fabian C. Moss and David Rizo. Authorship and ownership are
different things: the citation under "Attribution" below is what both licences
require of you.

HAMON is a standard plus its reference implementation, so it is released under
two licences — one for software, one for the specification and its data. Pick the
one that matches the file you are using.

    Software                   Apache License 2.0        LICENSES/Apache-2.0.txt
    Specification & data       CC BY 4.0                 LICENSES/CC-BY-4.0.txt

Software (SPDX: Apache-2.0)
---------------------------

    hamonpy/           the Python reference implementation, incl. generated
                       ANTLR parsers and the CLI
    tools/             build, release and validation scripts
    verovio-hamon/     build scripts
    site/, ICCCM26/    the code that builds them

Apache-2.0 is a software licence: unlike Creative Commons it handles source vs
binary distribution and grants patent rights explicitly, which is what an
implementable standard needs.

Specification and data (SPDX: CC-BY-4.0)
----------------------------------------

    grammar/           the normative EBNF and the JSON schema
    antlr/             the .g4 grammars
    conformance/       the corpus and the golden output
    fixtures/          the fixture corpus
    documentation/     prose documentation
    mei-customization/ the ODD files
    use-cases/         the worked examples (prose; any bundled third-party
                       corpus keeps its own licence — see below)

Third-party material
--------------------

Corpora and datasets that HAMON reads are NOT covered by the licences above.
They belong to their authors and keep their own terms — see the `license` field
of each entry in `datasets/manifest.json`, and any `LICENSE-*` file bundled
alongside an extract in `use-cases/`. `datasets/` ships a manifest only, never
the payloads.

No warranty

The Work is provided "as is", without warranty of any kind. See the warranty and
liability sections of the two licence texts.
