Agent-Oriented Architecture (AOA) is a robust framework that equips developers with tools to build and maintain intelligent multi-agent systems. Agents encapsulate state, behaviors, and interaction patterns, communicating via an asynchronous message bus. AOA includes modules for agent registration, discovery, and matchmaking, enabling dynamic service composition. Behavior modeling supports finite-state machines, goal-driven planning, and event-driven triggers. The framework handles agent lifecycle events like creation, suspension, migration, and termination. Built-in monitoring and logging facilitate performance tuning and debugging. AOA’s pluggable transport layer supports TCP, HTTP, and custom protocols, making it adaptable for on-premise, cloud, or edge deployments. Integration with popular libraries ensures seamless data processing and AI model integration.

Dial4JaCa is a Java library plugin for the JaCaMo multi-agent platform that intercepts inter-agent messages, encodes agent intentions, and routes them through LLM backends (OpenAI, local models). It manages dialogue context, updates belief bases, and integrates response generation directly into AgentSpeak(L) reasoning cycles. Developers can customize prompts, define dialogue artifacts, and handle asynchronous calls, enabling agents to interpret user utterances, coordinate tasks, and retrieve external information in natural language. Its modular design supports error handling, logging, and multi-LLM selection, ideal for research, education, and rapid prototyping of conversational MAS.

JASA provides a comprehensive set of Java libraries for building and running multi-agent system simulations. It supports agent lifecycle management, event scheduling, asynchronous message passing, and environment modeling. Developers can extend core classes to implement custom behaviors, integrate external data sources, and visualize simulation outcomes. The framework’s modular design and clear API documentation facilitate rapid prototyping and scalability, making it suitable for academic research, teaching, and proof-of-concept development in agent-based modeling.
