Added a top-level LICENSE (Apache License 2.0) for the repository.
Added LICENSE-OVERVIEW.md summarizing the licensing structure, with emphasis on the diversity of dataset licenses and the importance of reviewing individual terms.
Added DATASET-LICENSES.md — a comprehensive, grouped list of all data packages and their licenses, highlighting any ambiguous or unclarified licensing.
These changes improve transparency, support responsible use, and aid compliance for all users.
