+====== Specification & Architecture ======
+Generated by Gemini 2:
+You're looking to build a multi-tenant web application for museums to manage their media guides. Here's a potential architecture breakdown, focusing on key components and considerations:
+I. Core Requirements:
+ * User Management:
+   * Account creation and authentication for all users (museum administrators, room managers, general users - though the prompt doesn't explicitly mention general users accessing the guides directly, it's worth considering for future expansion).
+   * Role-based access control (RBAC) to manage permissions (e.g., museum admin, room manager).
+ * Museum Management:
+   * Creation and management of museum profiles (name, description, etc.).
+   * Association of users with specific museums (primarily administrators).
+ * Media Guide Management:
+   * Creation and management of media guides within a museum context.
+   * Potentially versioning of media guides.
+ * Room Management:
+   * Creation and management of rooms within a museum.
+   * Association of media components (text, audio, video, images) with rooms.
+   * Assignment of room managers (users with specific permissions for a room).
+ * Object Management:
+   * Creation and management of objects within a room.
+   * Association of media components with objects.
+ * User Nomination and Permissions:
+   * Mechanism for museum administrators (and possibly room managers, depending on the desired level of control) to nominate other registered users to manage specific rooms and their objects.
+   * Clear definition and enforcement of permissions for different roles at the museum, room, and object levels.
+ * Media Storage:
+   * Secure and scalable storage for various media types.
+II. Architectural Components:
+Here's a layered approach to consider:
+ * Presentation Layer (Frontend):
+   * Technology: React, Angular, Vue.js, or traditional server-rendered HTML/CSS/JavaScript.
+   * Responsibility:
+     * User interface for account creation, login, and navigation.
+     * Forms and workflows for managing museums, media guides, rooms, and objects.
+     * Displaying media content to end-users (if applicable).
+     * Handling user interactions and making API calls to the backend.
+     * Implementing role-based views and functionalities.
+ * Application Layer (Backend - API):
+   * Technology: Python (Django/Flask), Node.js (Express), Ruby on Rails, Java (Spring), Go.
+   * Responsibility:
+     * Handling API requests from the frontend.
+     * Authentication and authorization.
+     * Business logic for managing entities (museums, guides, rooms, objects, users, permissions).
+     * Data validation and processing.
+     * Interacting with the Data Access Layer and Media Storage.
+     * Implementing the user nomination and permission management logic.
+ * Data Access Layer:
+   * Technology: Object-Relational Mapper (ORM) like Django ORM, SQLAlchemy, Sequelize, Hibernate, or a direct database interaction layer.
+   * Responsibility:
+     * Abstracting database interactions from the Application Layer.
+     * Defining data models (schemas) for all entities.
+     * Performing CRUD (Create, Read, Update, Delete) operations on the database.
+     * Ensuring data integrity.
+ * Data Storage:
+   * Technology: Relational Database (PostgreSQL, MySQL), NoSQL Database (MongoDB), or a combination.
+   * Considerations:
+     * Relational Databases: Good for structured data and relationships between museums, rooms, objects, and users. Enforce data integrity through schemas and foreign keys.
+     * NoSQL Databases: Can be more flexible for evolving data structures, especially for media metadata. Might require more application-level management of relationships.
+     * Recommendation: A relational database like PostgreSQL or MySQL is likely a good starting point due to the structured nature of the data and the relationships between entities.
+ * Media Storage:
+   * Technology: Cloud-based object storage (AWS S3, Google Cloud Storage, Azure Blob Storage).
+   * Responsibility:
+     * Storing media files (images, audio, video).
+     * Providing secure access to media files.
+     * Scalability and cost-effectiveness.
+   * Considerations:
+     * Generating and storing thumbnails and different resolutions for images and videos.
+     * Content Delivery Network (CDN) for faster delivery of media to end-users (if applicable).
+ * Authentication and Authorization Service:
+   * Technology: Could be integrated into the Application Layer or a dedicated service (e.g., OAuth 2.0 provider).
+   * Responsibility:
+     * Handling user registration, login, and session management.
+     * Verifying user identity.
+     * Enforcing access control based on user roles and permissions.
+III. Key Design Considerations:
+ * Multi-Tenancy:
+   * Database Schema Approach: Each museum's data can be isolated in its own schema within a single database or in separate databases. This provides strong data isolation.
+   * Shared Database with Tenant ID: All museum data resides in the same tables, but each record is associated with a museum_id. This is simpler to manage but requires careful querying and can have implications for data isolation and scalability.
+   * Recommendation: Starting with a shared database with a museum_id is often easier to implement initially. If you anticipate a large number of museums or strict isolation requirements, consider the database schema approach later.
+ * Role-Based Access Control (RBAC):
+   * Define clear roles (e.g., museum_admin, room_manager).
+   * Associate permissions with each role (e.g., museum_admin can create rooms, room_manager can edit objects in their assigned rooms).
+   * Implement logic in the Application Layer to enforce these permissions based on the logged-in user's role and the context of the action.
+ * User Nomination and Permission Granting:
+   * Implement a mechanism for authorized users (e.g., museum admins) to nominate other users for specific roles within their museum (e.g., room manager for a specific room).
+   * Store these role assignments and the scope (e.g., user X is a room_manager for room Y in museum Z).
+   * Ensure that the authorization logic checks these specific assignments in addition to general roles.
+ * Data Relationships:
+   * Clearly define the relationships between entities in your data model (e.g., a museum has many rooms, a room has many objects, an object can have multiple media components). Use foreign keys in a relational database to enforce these relationships.
+ * API Design:
+   * Use a consistent and well-documented API (e.g., RESTful API using JSON).
+   * Implement proper authentication and authorization for all API endpoints.
+   * Consider versioning your API to handle future changes.
+ * Scalability:
+   * Design your application to handle increasing numbers of museums, users, and media content.
+   * Consider using a load balancer for the Application Layer.
+   * Choose scalable database and media storage solutions.
+   * Implement caching mechanisms to improve performance.
+ * Security:
+   * Implement secure authentication and authorization mechanisms.
+   * Protect against common web vulnerabilities (e.g., SQL injection, XSS).
+   * Securely store user credentials (e.g., using hashing and salting).
+   * Regularly audit your application for security vulnerabilities.
+ * Testing:
+   * Implement comprehensive unit, integration, and end-to-end tests to ensure the reliability of your application.
+ * Deployment:
+   * Choose a suitable deployment environment (e.g., AWS, Google Cloud, Azure).
+   * Implement a CI/CD (Continuous Integration/Continuous Deployment) pipeline for automated building, testing, and deployment.
+IV. Workflow Example (User Nominating a Room Manager):
+ * A museum administrator logs into the frontend.
+ * They navigate to the "Manage Rooms" section for their museum.
+ * They select a specific room.
+ * They initiate the "Nominate Manager" action for that room.
+ * A form appears where they can search for existing users by email or username.
+ * They select a user and confirm the nomination.
+ * The frontend sends an API request to the backend (e.g., /api/museums/{museum_id}/rooms/{room_id}/nominate-manager).
+ * The backend API endpoint:
+   * Authenticates and authorizes the requesting user (must be a museum admin for this museum).
+   * Validates the nominated user exists.
+   * Creates a record in a permissions table or similar structure, associating the nominated user with the room_manager role for the specific room in the specific museum.
+   * Potentially sends a notification to the nominated user.
+ * The frontend receives a success response and updates the UI.
+V. Technology Stack Considerations (Example):
+ * Frontend: React with TypeScript, Redux/Context API for state management, Material UI/Chakra UI for components.
+ * Backend: Python with Django REST Framework for the API, PostgreSQL for the database.
+ * Media Storage: AWS S3 with CloudFront CDN.
+ * Authentication: Django's built-in authentication or a library like Django Allauth.
+ * Task Queue (Optional): Celery for background tasks (e.g., processing large media files).
+ * Containerization: Docker for packaging the application.
+ * Orchestration: Kubernetes or Docker Compose for managing containers.
+VI. Future Considerations:
+ * Analytics: Track usage of media guides.
+ * Accessibility: Ensure the platform is accessible to users with disabilities.
+ * Internationalization (i18n) and Localization (l10n): Support multiple languages.
+ * Offline Access: Allow users to download media guides for offline use.
+ * Integration with other museum systems: Collection management systems, ticketing systems, etc.
+By carefully considering these architectural components and design principles, you can build a robust and scalable web application to meet the needs of museums for managing their media guides. Remember to iterate and adapt your design as your understanding of the requirements evolves.
