<p>The eDelivery specifications do not require restricting access to metadata hosted on SMPs. By default, all metadata is accessible without restrictions.</p><p>Starting from DomiSMP version 5.0, users can manage access by setting the visibility flag for each resource:</p><ul><li>Private: Only authenticated and authorised users can access the resource.</li><li>Public: The resource is accessible to all users.</li></ul><p>Additionally, access to DomiSMP metadata can be secured using HTTPS/Basic Authentication with access tokens and mutual TLS authentication. Note: Authentication must also be supported on the Access Point side. </p><p>For more information, refer to <a href="https://docs.edelivery.tech.ec.europa.eu/domismp/prod/5.1/#_domain_group_and_resources">Domain, Group and Resources</a>.</p>
