Sources

Our checks and packages rest on official material only: EU law, the EBA's published reporting package, and the AFM's own guidance. This page lists each source and what we use it for. The guides cite these sources inline.

EBA and EU law

The EBA publishes the templates, the data model, the validation rules and the sample packages for the DORA Register of Information. Our validator and template are built from these files.

Source	What we use it for
EBA: Preparations for reporting of DORA registers of information (opens in a new tab)	The data model, filing rules, CSV guidance, FAQ, common issues, value lists, technical checks and sample packages that our checks and package layout follow.
EBA: Reporting framework 4.0 (opens in a new tab)	The taxonomy and validation-rule workbook for the DORA module we validate against. The converter shows the ruleset it uses.
Regulation (EU) 2022/2554 (DORA) (opens in a new tab)	The legal duty to keep the register (Article 28(3)) and the definitions in our glossary.
Implementing Regulation (EU) 2024/2956 (ITS) (opens in a new tab)	The official templates and instructions, and the template titles on our template pages.

Dutch supervisors

The AFM sets how Dutch filers submit: the portal, the file name, the deadlines and the format. DNB collects registers from the institutions it supervises.

Source	What we use it for
AFM: Register of Information (opens in a new tab)	The file naming convention for our packages, the xBRL-CSV-only rule, the deadlines and the feedback process.
AFM: Q&A after the Q&A session, March 2026 (opens in a new tab)	The common rejection codes, the AFM's advice on choosing a converter, and field clarifications such as the open-ended end date in B_02.02.
DNB: Reporting DORA registers of information (opens in a new tab)	Context only: DNB's 2025 notice for the institutions it supervises. We build packages for AFM filers.

Registries for live checks

When online checks are on, we look up identifiers in two public registries. These lookups add evidence to your findings; they do not replace the checks the EBA runs after you file.

Source	What we use it for
GLEIF API (opens in a new tab)	Checking that each LEI exists and has a valid registration status, and that the entity countries in B_01.02 match GLEIF. The legal name is shown as evidence.
VIES technical information (opens in a new tab)	Checking that VAT numbers used as identifiers exist in the EU's VAT information exchange system.

How we keep this current

When the EBA or the AFM publishes new material, we review our checks and template against it. Each guide shows the date it was last reviewed.
