Traceability Report Framework
TRF (Traceability Report Framework) packages the evidence that complex products meet safety, security, and regulatory requirements. Each TWPack bundles artifacts, relationships, and provenance so teams, suppliers, and auditors can verify compliance from a single file.
Why Traceability Fails Today
- AI/ML systems rely on data lineage and model evidence that do not map cleanly to traditional requirements.
- Tool sprawl scatters tests, approvals, and releases across disconnected silos.
- Multi-tier supply chains exchange PDFs and spreadsheets, making verification slow and manual.

What TRF Delivers
| Capability | Description |
|---|---|
| TWPack | Deterministic ZIP archive containing manifest.json, artifacts.jsonl, links.jsonl, and provenance.json. |
| Modular schema | 4 core artifact types plus 64 domain-specific extensions across 10 domains, configurable through profiles. |
| Integrity | Optional signatures and JSON Schema validation for consistency and tamper evidence. |
| Analysis | CLI tooling for queries, coverage checks, and automated reporting. |
With vs. Without TRF
| Scenario | Traditional handover | TRF handover |
|---|---|---|
| Evidence package | Hundreds of PDFs, spreadsheets, and screenshots | Single .twpack file with linked artifacts |
| Verification time | Weeks of manual compilation | Minutes to validate and trace |
| Supply-chain transparency | Email attestations and unmanaged file shares | Cryptographically verifiable provenance |
Who Uses TRF
Automotive (ISO 26262, ISO 21434, UN-R155/156, ASPICE), AI/ML governance, aerospace (DO-178C), medical devices (IEC 62304), and any supply chain that needs audit-ready traceability.
Workflow at a Glance
- Extract artifacts and metadata from source tools.
- Transform the data into TRF schemas and relationship links.
- Package and optionally sign the TWPack bundle.
- Validate completeness and distribute to stakeholders.
Next Steps
- Understand the TWPack format.
- Learn core concepts: Artifacts, Links and relations, Manifest and provenance.
- Build your first pack with the Quickstart and Creating Your First Pack guides.
Current Version
v2.1.0 — Three-track architecture with complete OSS toolkit. Simplified JSON-based format optimized for 10K-100K artifacts. See the TRF repository and changelog.
Three-Track Strategy
TRF delivers value through three complementary tracks:
- Track 1: Format Specification — Open standard twpack format (ZIP + JSON), MIT licensed, vendor-neutral
- Track 2: OSS Toolkit — FREE production-ready tools for 10K-100K artifacts (this release)
- Track 3: TraceWeave Enterprise — Commercial platform for 100K-400M artifacts with AI features
