Two licences apply in this directory, one per atlas
===================================================

This directory holds two anatomical atlases from two unrelated sources. They
are kept in separate files on purpose, and they are NOT under the same licence.
Check which file you are redistributing before you redistribute it.


1. The male atlas — CC BY-SA 4.0 (share-alike)
----------------------------------------------

    manifest.json
    *_male.glb

Creative Commons Attribution-ShareAlike 4.0 International.

    Summary:   https://creativecommons.org/licenses/by-sa/4.0/

Derived from Z-Anatomy and BodyParts3D. Redistribution must preserve the
attribution in NOTICE and must keep these files under CC BY-SA 4.0.


2. The female atlas — CC BY 4.0 (attribution only)
--------------------------------------------------

    manifest_female.json
    *_female.glb

Creative Commons Attribution 4.0 International.

    Full text: https://creativecommons.org/licenses/by/4.0/legalcode
    Summary:   https://creativecommons.org/licenses/by/4.0/

From the NIH Human Reference Atlas. Redistribution must preserve the
attribution in NOTICE. There is no share-alike obligation on these files.


Why they are not combined
-------------------------

CC BY 4.0 material may lawfully be incorporated into a CC BY-SA 4.0 work, but
the combined work then has to be released under share-alike — which would
impose a condition on the HRA's meshes that their authors deliberately did not
choose. Keeping the two atlases in separate files makes this directory a mere
aggregation, and each work keeps the terms its authors set.

So: do not merge a `_male` mesh and a `_female` mesh into one file, and do not
merge the two manifests. Nothing in the application does, and the test suite
asserts it.

Neither licence applies to the Anatria3D application source code, which is
Apache-2.0 and merely aggregates these assets rather than adapting them.
