The DaMSym system (WP4) adopts a controlled access model based on roles, which determines the rights and functionalities available to each user.

Authentication is performed through the D4Science platform, which provides a secure and centralized infrastructure for identity management, using Keycloak as the SSO (Single Sign-On) provider.

This integration allows ITSERR and RESILIENCE users to access all related tools (such as Ubiquity, DaMSym, Sanctuaria, etc.) using the same credentials, while maintaining consistent control over profiles and permissions.

The system defines four main user profiles, each with a specific set of functionalities and permissions.

Each role determines the actions allowed within the interface, both for semantic search and for resource management and review.

Access to the DaMSym portal is provided via a dedicated URL: 🔗 https://damsym-itserr.d4science.org

The homepage displays the “Login” button located in the upper-right area of the interface.

By clicking it, the user is redirected to the authentication page managed by D4Science / Keycloak, where one of the following access methods can be selected:

• D4Science account – login using personal credentials already registered on the platform;
• Federated institutional account – login through an academic or university provider recognized by RESILIENCE;
• Other enabled Identity Providers – external login through compatible federated systems (e.g., partner institutions or accredited research centers).

The access flow consists of four main steps:

• the user selects “Login” from the top navigation bar of the portal;
• the system automatically redirects to the Keycloak / D4Science Login page;
• after authentication, Keycloak validates the credentials and returns a session token to the DaMSym platform;
• the user is redirected back to the homepage, now enriched with functionalities specific to their role.

The system keeps the session active for the duration of navigation or until manual logout via the user menu.

After authentication, the user profile icon appears in the upper-right corner of the screen, opening a dropdown menu containing the following entries:

• Dashboard → access to the personal section for managing resources and feedback;
• Logout → system logout and termination of the current session.

For users with the role of Researcher and Reviewer, the Dashboard presents a simplified view. Specifically, these users can access only the following sections:

• Dashboard – overview of personal resources and associated feedback;
• Corrections – section dedicated to managing modification requests related to texts and metadata.

For WP Lead users, the Dashboard includes the following sections, displayed in order:

• Dashboard – general overview of resources and feedback;
• Corrections – section dedicated to managing modification requests related to texts and metadata;
• Add Fonts – section for managing and adding fonts specific to the Church Slavonic language;
• Ratings Export – functionality dedicated to exporting feedback (ratings) provided by Reviewers.

For security reasons, the system implements a session timeout mechanism. In case of prolonged inactivity, the user is automatically logged out and redirected to the login page.

Authentication is entirely managed by D4Science / Keycloak, ensuring compliance with European data protection standards (GDPR) and with OAuth2 and OpenID Connect security protocols.

All credential exchanges occur in encrypted form (HTTPS/TLS).

Logout is performed by selecting the “Logout” entry from the user menu.

At the end of the session, the user is redirected to the public homepage in guest mode, temporarily losing access to all restricted functionalities.
