Maestro: Semantic Discovery and Orchestration of Web Services

The US Army plans to migrate C4ISR (Command, Control, Communications, and Computers, Intelligence, Surveillance, and Reconnaissance) systems toward network-centric objectives by (1) capturing capabilities (as services) from legacy systems, and (2) plugging them into the Distributed Common Ground System (DCGS) Integration Backbone (DIB). The DIB will provide the SOA service infrastructure and the pathway to interoperability with the Global Information Grid (GIG). While these efforts provide the infrastructure to achieve some level of interoperability, they are poised to hit the “Semantic Wall” due to lack of shared meanings among the legacy systems. Modus Operandi (MO) proposes an innovative intelligent meta-layer for service infrastructures that will capture and use shared meaning among services. Our Maestro approach harnesses semantic technologies to facilitate legacy system integration with the GIG.
