SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides guidance on implementing advanced credential semantics within W3C Verifiable Data Model (VCDM), specifically focusing on the crucial aspects of credential refreshing, defining terms of use, and incorporating supporting evidence.

Core Features & Use Cases

  • Credential Refreshing: Understand how to enable manual or automatic refresh of expired Verifiable Credentials (VCs) using the refreshService property.
  • Terms of Use: Learn to communicate the conditions under which a VC or Verifiable Presentation (VP) was issued or should be used via the termsOfUse property.
  • Evidence: Discover how to include supporting information with a VC to help verifiers establish confidence in the claims made, using the evidence property.
  • Use Case: When issuing a professional certification, use the evidence property to link to a video of the candidate demonstrating their skills, and use termsOfUse to specify that the certification is only valid for use within a specific industry.

Quick Start

Explain how to use the refreshService property to allow a holder to refresh a Verifiable Credential.

How do I implement credential refreshing in the W3C Verifiable Credentials Data Model?▼

Implement credential refreshing in the W3C Verifiable Credentials Data Model by configuring the `refreshService` property, which enables manual or automatic updates of expired Verifiable Credentials for holders.

What is the purpose of the termsOfUse property in Verifiable Credentials?▼

The `termsOfUse` property in Verifiable Credentials communicates the specific conditions under which a credential or Verifiable Presentation was issued or should be utilized by verifiers.

How do I add supporting evidence to a W3C Verifiable Credential?▼

Add supporting evidence to a W3C Verifiable Credential using the `evidence` property to include supplemental information, such as verification videos, that helps verifiers establish confidence in claims.

Can I specify usage restrictions for professional certifications using VCDM termsOfUse?▼

Yes, you can specify usage restrictions for professional certifications using the VCDM `termsOfUse` property to define conditions, such as restricting a credential's validity to a specific industry.

Does the VC Data Model 2.0 support automatic credential refresh for holders?▼

Yes, the VC Data Model 2.0 supports automatic credential refresh for holders through the implementation of the `refreshService` property to update expired credentials.
