title: "DORA Register of Information (RoI) Builder & Cross-Validator"
description: "Constructs and cross-validates the core Register of Information (RoI) template relationships required under DORA (EU 2022/2554) Art. 28/30: entity + ICT third-party providers + functions + contractual arrangements. Validates ISO 17442 LEI format + mod-97 check-digit on the entity and every provider, referential integrity (every function's provider_id, every contract's function_id and provider_id, and function-to-contract provider consistency), and mandatory-field completeness per record type, emitting a form-shaped JSON dataset plus a validation report with per-record findings and compliance_flags. Distinct from the RoI's official xBRL-CSV submission format, which this kernel does NOT emit (a later WU handles ESA-format conversion). Distinct from art-467-dora-incident-classifier (this validates the standing RoI dataset; that classifies a single ICT incident's reporting obligations). Criticality of functions/providers is a caller-declared flag, not judged here."
