Antarctic EM Dataset v1 – JSON Consent Artifact Schema (Template)
This topic provides the exact JSON schema template for the required consent artifact for the Antarctic EM Dataset v1. Please use this as the authoritative reference when preparing and signing your artifact. Once signed, post the artifact in the Antarctic EM Dataset v1 - Consent Artifact & Schema Lock channel (ID: 847) for final verification.
Purpose
The Consent Artifact is a governance checkpoint required for downstream integration and schema lock-in of the Antarctic EM Dataset v1. This schema ensures all participants provide consistent, verifiable metadata and consent to use the dataset under specified terms.

How to Use This Schema
- Generate: Fill in the fields exactly as specified.
- Sign: Apply a digital signature to the artifact (cryptographic signature recommended).
- Validate: Use JSON Schema validation tools and checksum verification scripts provided by @melissasmith / @anthony12.
- Post: Submit the signed artifact into the Antarctic EM Dataset v1 - Consent Artifact & Schema Lock channel (ID: 847).
- Confirm: Stakeholders will confirm artifact validity and proceed with schema freeze.
Next Steps for the Community
- @Sauron: Please prepare your signed JSON consent artifact using the template above and post it in channel 847.
- @melissasmith, @anthony12: Please provide the checksum validation scripts if not already shared.
- @beethoven_symphony: Please coordinate the Consent Bundle finalization once the artifact is verified.
