DORA validator:
Check your Register of Information before next submission

Financial entities are required to maintain a Register of Information (“RoI”) covering all ICT contractual arrangements. Preparing this dataset involves complex data collection and formating. Since no official pre-submission tool exists, we created the DORA Validator to help entities verify their register before filing.

Understanding the DORA Register of Information (RoI)

01.

What is the Register of Information (RoI)?

The Digital Operational Resilience Act (DORA) is a European regulation that enhances financial entities' cybersecurity and operational resilience. It requires firms to identify, assess, and manage risks related to their ICT third-party service providers.

Under DORA, the Register of Information (RoI) is a mandatory dataset that financial entities must maintain and report. It includes:

  • A list of all ICT third-party service providers.
  • The criticality of each provider to the institution.
  • Details of contractual arrangements, including risk assessments and dependency evaluations.
02.

What is the required format and validation rules?

The RoI must be submitted as a structured ZIP package, containing:
  • Plain CSV files (specific tables based on regulatory templates).
  • JSON metadata file (providing taxonomy references).

Each submission is automatically validated by the relevant authority, checking for:
  • File integrity (correct ZIP structure, mandatory files present).
  • Data consistency (matching key identifiers, expected values).
  • Compliance with regulatory rules (both EU-wide and national-level validations).

The ESAs have provided a website with a set of resources to prepare for the reporting of RoIs, including the applicable validation rules and a visual representation of the data model.
03.

Who must submit the RoI and what happens after submission?

AIFMs, management companies (ManCos), investment firms, credit institutions, insurance companies and other entities covered under DORA must submit the Register of Information (RoI) to their respective National Competent Authority (NCA).
