Civic Transparency PTag Specification
Normative specification for privacy-preserving provenance tags (PTags) Includes JSON Schemas and OpenAPI definitions for transparency APIs.
Schemas
| Schema | Purpose | Status |
|---|---|---|
ptag.schema.json |
Per-post behavioral metadata | Draft |
ptag_series.schema.json |
Aggregated time PTagSeries API responses | Draft |
ptag_api.openapi.yaml |
REST API specification | Draft |
Implementation Flow
- Generate provenance tags when posts are created (per
ptag.schema.json). - Aggregate tags into time buckets (with k-anonymity ≥ 100).
- Expose aggregated data via REST API (per
ptag_api.openapi.yaml).
See API documentation for complete specification.
Designed for Privacy
- All responses maintain k-anonymity (k≥100).
- No individual posts or users are exposed.
- Rare categories (<5%) are grouped as "other".
- Geographic data limited to country-level or 1M+ (ISO codes).
