Plugin System Architecture Components¶

The NCA plugin system provides a framework for extending the functionality of the NeuroCognitive Architecture through plugins. It consists of the following key components:

Core Plugin Components¶

Plugin Registry:
Plugin Registration: Handles plugin registration
Plugin Discovery: Discovers available plugins
Plugin Catalog: Maintains a catalog of available plugins
Plugin Versioning: Manages plugin versions
Plugin Metadata: Stores plugin metadata
Dependency Management: Manages plugin dependencies
Plugin Loader:
Plugin Initialization: Initializes plugins
Hot Loading: Supports loading plugins without restart
Plugin Validation: Validates plugin integrity and compatibility
Isolation Mechanism: Isolates plugins from each other
Dependency Resolution: Resolves plugin dependencies
Config Loader: Loads plugin configurations
Plugin Lifecycle:
Plugin Activation: Activates plugins
Plugin Deactivation: Deactivates plugins
Plugin Updates: Handles plugin updates
Plugin Rollbacks: Supports rolling back plugin updates
Health Monitoring: Monitors plugin health
Controlled Restart: Provides controlled restart capabilities

Plugin APIs¶

Extension Points:
Core Extensions: Extension points for core functionality
Memory Extensions: Extension points for memory system
LLM Extensions: Extension points for LLM integration
UI Extensions: Extension points for user interfaces
Health Extensions: Extension points for health system
Custom Extensions: Framework for custom extension points
System Hooks:
Event Hooks: Hooks into system events
Lifecycle Hooks: Hooks into system lifecycle events
API Hooks: Hooks into API operations
Data Hooks: Hooks into data operations
Processing Hooks: Hooks into processing pipelines
Custom Hooks: Framework for custom hooks
Plugin Communication:
Event Bus: System-wide event bus
Pub/Sub System: Publish/subscribe messaging system
Shared Memory: Shared memory for inter-plugin communication
Message Passing: Direct message passing between plugins
Service Discovery: Discovers services provided by plugins
RPC Mechanism: Remote procedure call mechanism

Plugin Management¶

Admin Interface:
Admin Dashboard: Dashboard for plugin management
Plugin Controls: Controls for plugin operations
Plugin Monitoring: Monitors plugin status and health
Plugin Logs: Displays plugin logs
Plugin Marketplace:
Plugin Store: Central repository for plugins
Plugin Publishing: Mechanisms for publishing plugins
Plugin Distribution: Distributes plugins to systems
Plugin Reviews: User reviews and ratings for plugins
Plugin Security:
Plugin Sandbox: Sandboxes plugins for security
Permission System: Manages plugin permissions
Code Signing: Ensures plugin authenticity
Security Verification: Verifies plugin security

External Connections¶

The plugin system connects with: - External Plugins: Third-party plugins - Community Plugins: Plugins from the community - Enterprise Plugins: Plugins from enterprise partners

Internal Connections¶

The plugin system connects to: - NCA Core System: Core NeuroCognitive Architecture system

The plugin system is designed to provide a robust, secure, and extensible framework for adding functionality to the NCA, with support for various types of plugins from different sources.
