SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When you must issue or verify a credential type that no existing iGrant.io template skill covers, you need a reliable way to find or build the correct claim path pointer schema or DCQL query without guessing attribute names, namespaces, or formats. ## Core Features & Use Cases - Registry-first lookup: Searches the iGrant.io verifiable data registry for claim path pointer credential schemas and DCQL query templates, taking the latest version directory per credential. - Rulebook fallback: Falls back to the WE BUILD attestation rulebooks catalog and builds a claim path pointer document from rulebook attribute definitions, including mso_mdoc namespaces and dc+sd-jwt vct values. - Guided setup interview: Collects environment (demo or staging), OWS API key, credential type, role, format, and trust-list registration status before any code is written. - Use Case: You need to verify a European Business Wallet attestation that has no prebuilt skill. The agent checks the registry, finds the matching WE BUILD rulebook, derives the claim path pointer document, and hands off to the issuer or verifier API skills. ## Quick Start Ask the agent to find a credential schema or DCQL query for your credential type using the iGrant.io schema discovery skill, specifying whether you need to issue or verify it.

FAQPage Schema
How do I find a credential schema for the iGrant.io Organisation Wallet Suite?▼

Check the iGrant.io verifiable data registry first, which holds claim path pointer credential schemas and DCQL query templates with one directory per version. Take the latest version directory containing one schema and one metadata file per credential format.

What do I do if no credential schema exists in the iGrant.io registry?▼

Check the WE BUILD attestation rulebooks catalog for a rulebook defining your credential type. Build the claim path pointer document from its attribute definitions, with one claims entry per attribute and the correct namespace for mso_mdoc or vct value for dc+sd-jwt.

Which credential formats does iGrant.io schema discovery support?▼

It supports dc+sd-jwt, jwt_vc_json, and mso_mdoc formats. The recommended default is dc+sd-jwt unless the applicable rulebook requires mdoc, in which case the path array uses the rulebook namespace and attribute name.

Do I need an API key to use iGrant.io credential schemas?▼

Yes, you need an iGrant.io Organisation Wallet Suite API key from support@igrant.io, valid for either the demo or staging environment. Keep it server-side in an environment variable or secret manager, never in the browser.

When should I not use schema discovery for credentials?▼

Skip discovery when an existing igrantio-credential-schema or igrantio-dcql-query template skill already covers your credential type. Discovery is the fallback path for credential types with no prebuilt template.
