This paper presents Liaison (Liaison, 2025) a new open- source tool designed to address challenges related to portability, security, and intellectual property when sharing Functional Muckup Units. Built on the Functional Muckup Interface 3.0 standard, Liaison has a server-client architecture that leverages Zenoh for communication (Corsaro et al., 2023. Zenoh is a novel pub/sub/query protocol that supports a variety of network topologies such as peer-to-peer, routed, mesh and brokered communication with minimal configuration, setting Liaison apart from similar tools. An example of a case that led the authors to develop this tool (Software-in-the-Loop testing of sail control systems for wind assisted propulsion of ships (Laursen et al. 2023)) is presented.
