Contributor Licence Agreement

Standard: SIGNET · Steward: Concert Foundation · Version: 1.0

Status — ratified. This document formalises the contribution terms already stated in CONTRIBUTING.md. The authoritative, legally reviewed version is published by Concert Foundation at https://concert.foundation/governance/cla; if the two differ, the published version governs.

Thank you for contributing to SIGNET. To keep the standard open for everyone — and to give every implementer the patent assurance a standard requires — Concert Foundation asks each contributor to accept this Agreement before their contribution is merged.

By signing (see How to sign below), You agree to the following with respect to each Contribution You submit to this project.

1. Definitions

• "You" means the individual who submits a Contribution, or the legal entity on whose behalf the Contribution is submitted under a Corporate CLA.
• "Contribution" means any original work of authorship — code, schema, codelist values, documentation, examples, or other material — that You intentionally submit to this repository (e.g. via pull request), including any modification of an existing work.
• "Concert" means Concert Foundation, the steward of the SIGNET standard.

2. You keep ownership

This Agreement does not transfer ownership of Your Contribution. You retain all right, title, and interest in it. You grant Concert the licences in §3 and §4 so the standard can remain open; You remain free to use Your Contribution for any other purpose.

3. Copyright licence

You grant Concert and recipients of material distributed by Concert a perpetual, worldwide, non-exclusive, royalty-free, irrevocable copyright licence to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contribution and such derivative works — including the right to publish Your Contribution under the open licences in the Concert IP & Licensing Policy (CC0 1.0 for the normative artifacts; Apache-2.0 for the conformance suite).

4. Patent licence (W3C model)

You grant Concert and recipients of the standard a perpetual, worldwide, non-exclusive, royalty-free, irrevocable (except as stated below) patent licence to make, have made, use, offer to sell, sell, import, and otherwise transfer the work, where such licence applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution alone or by combination of Your Contribution with the project to which it was submitted.

If any entity institutes patent litigation against You or any other contributor alleging that Your Contribution, or the work to which You contributed, constitutes direct or contributory patent infringement, then any patent licences granted under this Agreement for that Contribution terminate as of the date such litigation is filed.

5. Your representations

You represent that:

1. each Contribution is Your original creation, or You have the right to submit it under the terms of this Agreement;
2. You are legally entitled to grant the above licences, and — if Your employer has rights to intellectual property You create — that You have received permission to make the Contribution on behalf of that employer, or that the employer has waived such rights, or that the employer has executed a Corporate CLA;
3. each Contribution is provided "as is", without warranties of any kind; and
4. You will notify Concert if any statement above becomes inaccurate.

6. Neutrality

Acceptance of Your Contribution under this Agreement gives no contributor — and no commercial operator, including Score Networks — any preferential position in the standard. The same terms apply to everyone (see the Concert IP & Licensing Policy).

7. Corporate contributors

If You are contributing on behalf of an organisation, an authorised signatory should execute the Corporate CLA (one signature covers all of the organisation's staff) rather than signing individually. Contact hello@concert.foundation.

How to sign

This project uses an automated CLA assistant. When You open Your first pull request, a bot will check whether You have signed. If You have not, it will comment with a link to this document and ask You to add a single comment on the pull request:

I have read the CLA Document and I hereby sign the CLA

Your GitHub username and the pull-request reference are then recorded as Your signature in the signatures/ store on the cla-signatures branch. Signing once covers all of Your future contributions to this repository under this CLA version. A new major version of the CLA requires re-signing.
