1. The process for recording reference data in RIAD is described in the data exchange specifications, to which NCAs have access. Each NCA shall record information either via the standard ESCB facility, via online updates, or, depending on national arrangements, via the transmission channel already in use by the NCB in its participating Member State. In each case, the NCAs shall record the reference data required for resident entities under this Guideline via the dedicated ‘SUP’ source in RIAD.
2. Prior to recording reference data in RIAD, NCAs shall carry out validation checks to ensure that the relevant reference data complies with the data exchange specifications. NCAs shall maintain an adequate set of controls to minimise operational errors and ensure the accuracy and consistency of the reference data recorded in RIAD.
3. Where NCAs are unable to access RIAD due to a technical failure, they shall use the contingency facility envisaged for that eventuality or transmit the reference data by encrypted email to the following address: RIAD-Support@ecb.europa.eu.
4. When recording reference data, NCAs may use their national character set, provided they use the Roman alphabet. They shall use Unicode (UTF-8) to correctly display all special character sets when receiving information from the ECB via RIAD.
5. An NCA may make technical arrangements with the NCB in its participating Member State for the recording of the reference data in RIAD pursuant to this Guideline. However, even in such case, the NCA shall remain responsible for the accuracy and quality of the reference data.
