Understanding DORA Compliance: Key Technical Challenges and Solutions

Listen to this Post

The Digital Operational Resilience Act (DORA) regulation has extended its deadline for submitting the Registre d’Information (ROI) to May 23, 2025, as announced by the AMF (Autorité des marchés financiers). This extension comes due to widespread technical errors in submissions.

Major Technical Errors Identified

Structural Errors

  • Code 103: Invalid ZIP file structure (incorrect hierarchy)
  • Code 306: Non-UTF-8 encoding issues

Data Errors

  • Code 801: Non-compliant column names
  • Code 805: Empty key fields
  • Code 807: Foreign key issues
  • Code 808: Errors in `FilingIndicators.csv`

You Should Know: Key Steps for Compliance

1. Validate File Structure

Ensure ZIP files follow the correct hierarchy:

unzip -t submission.zip  Test ZIP integrity 
file -i .csv  Check encoding (must be UTF-8) 

2. Check CSV Formatting

Use Linux commands to verify CSV structure:

head -n 1 .csv  Check column headers 
awk -F ',' '{print NF; exit}' .csv  Verify column count 
grep -v '^[^,],[^,],[^,]$' .csv  Find malformed rows 

3. Automate Data Validation

Use Python to validate key fields:

import pandas as pd 
df = pd.read_csv("FilingIndicators.csv") 
if df.isnull().any().any(): 
print("ERROR: Empty key fields detected!") 

4. Submit Early & Iterate

The AMF recommends early submissions via ROSA to identify errors before the final deadline.

What Undercode Say

DORA compliance requires technical precision in file structure, encoding, and data integrity. Financial institutions must:
– Automate validation using scripts.
– Test submissions early to avoid last-minute failures.
– Use UTF-8 encoding (iconv -f ISO-8859-1 -t UTF-8 input.csv > output.csv).
– Verify foreign key relationships in databases.

Key Linux Commands for Compliance

iconv -f WINDOWS-1252 -t UTF-8 data.csv > fixed_data.csv  Fix encoding 
zip -r dora_submission.zip .csv  Create compliant ZIP 
cksum .csv  Verify file integrity 

Windows PowerShell Checks

Get-Content data.csv | Select -First 1  Check headers 
Import-Csv data.csv | ForEach { if ($_.KeyField -eq "") { Write-Warning "Empty key field!" } } 

Expected Output:

A technically compliant DORA submission with:

✔ Valid ZIP structure

✔ UTF-8 encoded CSVs

✔ No empty key fields

✔ Proper foreign key relationships
