Content Under CC BY

Papers, data, and the technical library are released under Creative Commons Attribution, so anyone may reuse them provided they credit the source.

What CC BY grants

Kronos releases its written and data content under the Creative Commons Attribution license (CC BY). Under it, anyone may copy, redistribute, adapt, and build upon the material — including for commercial purposes — provided they give appropriate credit and indicate any changes. It is one of the most permissive standard content licenses, and it is deliberate: content that cannot be freely reused cannot be freely checked.

Why the most permissive content license

• Reproduction requires copying: a reviewer must be able to duplicate figures and data to test them.
• Reuse compounds credibility: when others cite and extend the work, the record spreads with attribution intact.
• Attribution keeps provenance clean: reuse is fine, but the origin of a claim stays traceable.

What it applies to

CC BY covers the papers, the open datasets, and the public technical library. Code is handled separately, under an open-source software license better suited to source; see code under Apache and the license-choice rationale.

The obligation that comes with reuse

The single condition — attribution — is the mechanism that keeps the open record honest as it travels. If a downstream author reuses a Kronos figure, the credit line points a reader back to the deposit and its stated scope, including the honest gates. Guidance on how to attribute cleanly is under metadata and citation.

Open content is only useful if it can be moved. CC BY lets it move while keeping its source attached.
