§26 EU Register Submission¶

Version: v3.0

Defines the rcan-eu-register-v1 schema — a submission package for the EU AI Act Art. 49 obligation to register high-risk AI systems in the EU AI database before placing them on the market.

Overview¶

EU AI Act Art. 49 requires providers of high-risk AI systems to register their systems in the EU database administered by the European AI Office before placing the system on the market or putting it into service. RCAN §26 defines a submission package that wraps a signed FRIA document with the registration metadata required by the database.

Art. 49 registration is scoped per AI system (per model), not per individual deployed robot — a provider with a fleet of the same model registers the model once. The top-level rmn field identifies which model this submission is for; system.rrn records which specific robot produced the submission (for audit/provenance only).

Prerequisite: A valid signed rcan-fria-v1 document is required as input. The submission package references it by filename and the two files must be submitted together to the EU AI database.
