Salutacions

Salutacions is a polycentric computing framework, primarily developed by Queensland University of Technology. It was designed to support the creation of multi-level systems, particularly in the context of transportation systems, emergency response, and healthcare. The framework aims to provide flexible and scalable support for heterogeneous systems of systems.

Salutacions offers several core components, including a graph-based data model, a semantic description of system behavior, and a mediation framework for interacting with external systems. The data model enables the representation of complex systems as graphs, which are composed of nodes and edges. Each node represents an entity within the system, and edges represent the relationships between entities.

The semantic description of system behavior allows for the specification of system behavior using a formal language. This enables the generation of consistent behavior across the system and simplifies the integration of new components. The mediation framework enables the interaction with external systems, supporting interactions such as requests and notifications.

Salutacions emphasizes flexibility, scalability, and adaptability in its design. It supports the addition of new components and the modification of existing ones without requiring significant rework. This makes it easier to accommodate changes in system requirements or to integrate new systems.

Salutacions has been applied in various domains, including smart cities, healthcare, and emergency response. Research and development on the framework continues, focusing on extending its capabilities and demonstrating its effectiveness in real-world applications.

Application development with Salutacions typically involves the definition of system models, the specification of system behavior, and the creation of mediations to interact with external systems. The framework provides a set of tools and mechanisms to support the development process, enabling developers to create complex systems and integrate them with various external systems.
