What should a Data Act request log prove for Audit Evidence And Request Logs implementation evidence?
The Data Act context is the starting point for this answer. A request log should prove the route from intake to outcome. For connected-product and related-service data, record whether the requester is the user, a party acting on the user's behalf, or a third party chosen by the user. The log should identify the product or related service, requested data and metadata, format, timing, delivery route, and any refusal, suspension, limitation, compensation, or dispute route.
Keep the log narrow. The Data Act allows data holders to verify user or third-party status, but it also says they should not require more information than necessary and should not keep access information beyond what is necessary for execution, security, and maintenance of the data infrastructure.
- Minimum fields: request ID, requester identity and role, product or related service, data category, metadata needed to interpret the data, request channel, decision, delivery or refusal date, responsible owner, and cited Data Act article.
- For user access, record whether data were directly accessible or had to be made available by the data holder in a structured, commonly used, machine-readable format.
- For third-party sharing, record the user's instruction, third-party identity check, delivery format, and any Article 8, Article 9, trade secret, security, or GDPR condition that changed the response.
Articles 3, 4, and 5 ground user and third-party access logs, including the limit on keeping more access information than necessary.
