SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides guidance on implementing W3C Verifiable Credentials within the OpenID4VP framework, ensuring interoperability and correct data handling.

Core Features & Use Cases

W3C VC Format Parameters: Understand and utilize parameters like type_values for credential matching.
Claims Matching: Learn how claims_path works for selecting specific data within VCs.
Presentation Formats: Covers both JWT-signed VCs and JSON-LD (LDP) VCs, including their respective metadata, request, and response structures.
Use Case: When a verifier needs to request a specific type of W3C Verifiable Credential (e.g., a driver's license) using OpenID4VP, this skill details how to construct the Credential Query and interpret the Presentation Response.

Quick Start

Use the oid4vp-format-w3c-vc skill to understand how to request a W3C Verifiable Credential with the type 'UniversityDegreeCredential'.

FAQPage Schema

How do I implement W3C Verifiable Credentials in OpenID4VP presentation flows?▼

To implement W3C Verifiable Credentials in OpenID4VP, you use specific credential format parameters like `type_values` for credential matching and construct a `Credential Query` to request presentations. This ensures interoperability and correct data handling during the presentation exchange.

How does claims matching work for selecting specific data within W3C VCs?▼

Claims matching for W3C VCs uses a `claims_path` parameter to select specific data within the credential. This allows verifiers to pinpoint exact claims needed from a W3C Verifiable Credential, such as extracting a degree from a UniversityDegreeCredential during an OpenID4VP request.

Does OpenID4VP support both JWT-signed and JSON-LD Verifiable Presentations?▼

OpenID4VP supports both JWT-signed VCs and JSON-LD (LDP) VCs. The framework provides detailed specifications for handling the respective metadata, presentation requests, and response structures required for each distinct Verifiable Presentation format.

What is the best way to request a specific W3C Verifiable Credential type from a verifier?▼

The best way to request a specific W3C Verifiable Credential type is by constructing a `Credential Query` using `type_values` for credential matching. You then interpret the `Presentation Response` structure to securely process the returned credential data.

When do I need to use credential format parameters in a presentation exchange?▼

You need to use credential format parameters in a presentation exchange when a verifier requests a specific type of W3C Verifiable Credential. Parameters like `type_values` and `claims_path` ensure the correct credential and claims are matched and retrieved from the holder.
