Yesterday in the 25.07.2024 the Digital Product Pass Release v4.0.1 was finally published. It is a hotfix from the v4.0.0 major release, which contained some bugs and issues.

This release contains several improvements in the stability of the application and in the security.

If you have followed the previous version of the application you would have seen that several bugs were present:

• [DPP] [BUG] EDC Contract exchange metadata is shown partially #373
• [DPP] [BUG] Frontend request parsing affects data integrity on verifiable aspects #372
• Policy Check #325

• Other bugs not in issues:

• Authentication with Keycloak was adding "iss" to the url all the time.

They all were fixed now!

Added Compatibility Matrix

I have added the compatibility matrix for the Digital Product Pass, in this way the different dependencies can be visualized properly.

Added compatibility to IRS 7.4.0

Now the backend is compatible with the latest IRS 7.4.0 helm version. Enabling even faster relationships retrievals.

Issues Fixed

Fixed Integration Between EDC 0.7.3 and the backend

There was a policy definition problem in the backend helm charts that do not allowed the backend to accept the EDC policies. Because of data sovereignty.

Fixed DSP Endpoint Resolution Bug

There was a bug related to the dsp endpoint resolution, when we received it from the Digital Twin, we were not able to build correctly the dsp endpoint with the provider endpoint.

Fixed Digital Product Pass Verification Typos

There were some typos in the digital product pass verification add-on. They were fixed in this released.

Digital Product Pass Verification Add-on Backend Implementation

Digital Product Pass Verification Add-on Implementation is finally available at the digital product pass backend.
The backend was refactored to be constructure in a modular way. All the core components of the backend were moved into the 'core' module.
The 'verification' module includes all the functionality required to verify credentials using the simple wallet component.

Digital Product Pass Simple Wallet from DPP Verification Add-on Available

A functional wallet developed in Python is now available. It is a minimal viable wallet component that can be used to:

• Generate Valid JSON-LD @context schemas from existing SAMM Models standarized in Catena-X.
  • So that the data from the aspect models can be placed inside of the verifiable credentials.
• Issue a verifiable credential with data model v2 with a DID Web resolvable proof and JsonWebSignature2020
• Verify a verifiable credential with a DID Web resolvable proof from typy JsonWebKey2020
• Provide a standard did.json endpoint for a specific Bussiness Partner Number
• Manage the authorization by bpn and api keys
• Store an log of your signed verifiable credentials

Digital Product Pass Verification Add-on Schemas and Semantics Available

Now the semantic models for the Certified Data Credential and some examples are available under dpp-verification semantics.
Also its available the json-ld schemas for the digital product pass aspect model and the certified data credential under schemas.

Digital Product Pass Verification Add-on Frontend Implementation

Visualize if the credential you are retriving is verifiable or not. Be able to refresh the verification of the credential signature on the fly and be able to visualize the issuer, owner and wallet that handled the verification.

Updated

Repository Refactored

The repository was refactored and prepared for the release R24.08 of Catena-X. Cleaning all the Consortia releated information in the documentation.

Issues Fixed in the Frontend

Several minor bugs that were affecting the stability of the application were fixed and the frontend code was refactored.

Digital Product Pass Verification Documentation Updated

The Digital Product Pass Verification Documentation was updated in order to match the latest updates done and specified during the implementation.
Now the documentation contains SAMM models, schemas, example payloads, details of the Implementation in the application, new structure, new diagrams, examples on how to link digital twins in type level, detailed explanations on why verification is necessary and the added value.
