Why DataPass?

A standard designed for real-world data submission and low-resource language stewardship

Rights Clarity

Clear licensing, commercial use status, and personal data characterization in a machine-readable format.

Provenance Tracking

Document source types, geography, collection windows, and data origins with structured fields.

Access Information

Standardized availability status with request instructions and artifact pointers.

Language Stewardship

BCP-47 tags, autonyms, scripts, writing direction, and code-switching metadata for low-resource languages.

Schema Validation

Strict JSON Schema with additionalProperties: false ensures consistent, predictable data cards.

Community Driven

PR-based contribution workflow for data cards, schemas, and translations.

Strict Schema for Reliable Data Cards

The LLM Data Card v1.0 schema uses additionalProperties: false throughout, ensuring every field is intentional and validated.

  • Required sections: core, data, rights, provenance, access
  • Optional sections: artifacts, processing, quality, synthetic, use, governance, safety, community, sources, stats, extensions
  • Conditional rules: Smart validation that requires fields based on context

Conditional Validation Examples

  • data.kind = "synthetic" requires synthetic.generation_method
  • rights.contains_personal_data != "none" requires rights.consent_mechanism
  • access.availability = "restricted" requires request_instructions or url
  • data.structures = "translation-pairs" requires languages.length >= 2
