Three-Track Strategy
TRF (Traceability Report Framework) delivers value through three complementary tracks, each serving different needs and markets.
Overview
Track 1: Format Specification
The twpack file format - An open standard for traceability data exchange.
What It Is
- File format specification (like PDF, SQLite, or MP4)
- ZIP archive containing JSON files
- JSON Schemas for validation
- Vendor-neutral and domain-agnostic
Who Uses It
Everyone - Track 1 is the foundation that both Track 2 and Track 3 build upon.
Key Features
