Introduction
Please note that this content is under development and is not ready for implementation. This status message will be updated as content development progresses.
The UN Transparency Protocol (UNTP) Test Suite is a comprehensive set of tools for implementing, testing, and demonstrating the UNTP specification. It provides everything needed to issue UNTP-compliant verifiable credentials, validate them against the specification, and verify conformance across technical and semantic dimensions.
The repository comprises four primary components:
Reference Implementation
The Reference Implementation is a multi-tenant application for issuing, storing, and verifying UNTP-compliant verifiable credentials — including Digital Product Passports (DPPs), Digital Conformity Credentials (DCCs), Digital Facility Records (DFRs), and more.
It acts as an on-ramp for organisations and implementers to experiment with UNTP before committing to changes in their production systems, and is used to facilitate pilots and demonstrations that showcase the value of UNTP at low cost.
The Reference Implementation delegates to several dependent services for credential signing, storage, and identifier resolution, and supports a pluggable adapter architecture for integrating with different service providers.
UNTP Playground
The UNTP Playground is a web application for validating UNTP credentials against the specification. Upload a credential and receive immediate feedback on whether it conforms — useful both as a development aid during implementation and as a demonstration tool.
Test Suites
The UNTP test suite is being refactored. It will be distributed as a Node.js library and a command-line interface, with significant improvements to the testing infrastructure planned across subsequent releases.
Extensibility
The Test Suites and Reference Implementation can be extended to meet the specific needs of industries or value chain actors while still conforming to the core UNTP specification. This flexibility allows for customisation without compromising the protocol's fundamental principles.
