# Licence for the Gap Tracer data

The files in this folder (`skills.json`, `meta.json` and `activities/`) are a selection and adaptation of the Marble Skill Taxonomy, made for the Gap Tracer page on choosewise.education. They are offered under the same licences as the original:

> Marble Skill Taxonomy (v1) · © Generative Spark, Inc. (Marble) · https://withmarble.com · licensed under ODbL 1.0 (database) and CC BY-SA 4.0 (content).

- Database (the collection, structure, IDs and relationships): [Open Database License 1.0](https://opendatacommons.org/licenses/odbl/1-0/)
- Text written by Marble (skill names, descriptions, evidence, check questions and activities): [Creative Commons Attribution-ShareAlike 4.0](https://creativecommons.org/licenses/by-sa/4.0/)

What we changed: we removed activities that need Marble's app, activities whose shown text contained a curriculum omission marker and activities that refer to NGSS, kept only the fields the page shows, and replaced curriculum codes with readable labels for the Common Core State Standards, the Australian Curriculum v9 and the National Curriculum in England.
