| NOTAS: | "The latest CERRE issue paper on the DMA discusses some key issues and trade-offs that may arise in implementing the horizontal and vertical interoperability provisions of the regulation. The authors first discuss the implementation of the horizontal interoperability provision in the DMA (Article 7). They argue, on the one hand, that horizontal interoperability will require proper management of user consent and careful interface design and, on the other, that achieving horizontal interoperability poses significant technical challenges to:
• resolve identities across providers;
• establish secure connections; and
• deal with malicious users. Solving these technical challenges will raise trade-offs for which there are no easy choices.
Second, they briefly discuss general principles for the implementation of vertical interoperability provisions, i.e., specifically Articles 6(4) and 6(7). Here, they argue for five principles:
• screening of access requests,
• screening of access seekers,
• gatekeeper-led definition of interfaces,
• equivalence of input, and
• a neutral choice architecture.
The authors also emphasise that there can be interactions between the four principles so that they must be evaluated in concert, and not in isolation." |
