How do I construct a DCQL query for a verifiable presentation?▼

Build a DCQL query by specifying required credential sets, individual claims, trusted authorities, and claims path pointers for JSON or mdoc formats. This ensures Verifiers request exactly what they need from Wallets.

How does DCQL handle claims path pointers for mdoc and JSON credentials?▼

Claims path pointers in DCQL allow Verifiers to target specific data elements inside JSON and mdoc verifiable credentials. This ensures precise extraction of required claims during presentation.

Can DCQL specify trusted authorities when requesting verifiable credentials?▼

Yes, DCQL query construction supports specifying trusted authorities. This allows Verifiers to filter verifiable credentials based on the approved issuer within the EUDI ecosystem.

How do I parse an existing Digital Credentials Query Language query?▼

Parsing a DCQL query involves analyzing its credential queries, claims queries, and credential set logic. This reveals exactly what claims and trusted authorities the Verifier requested.
