We propose to design an object-oriented scripting language that enables the discovery and rapid assembly of publish-subscribe fuselets through ontology-aware query on both data and program metadata, to implement it in an extensible manner by mapping onto existing interpreters and runtime infrastructures using source-to-source-transformation and library extensions, and to design and implement monitoring support which can serve as the foundation for an interactive development environment for discovery-based fuselet assembly. The provision of semantically conservative extensions which realize advanced query and discovery capabilities is vital to the effective integration of evolving COTS scripting and XML technologies into the next generation of battlefield information systems, and will have broad applicability in the larger arenas of document retrieval and networked computation.
Benefits: A scripting language for the rapid assembly of data fusion processes whose query and discovery facilities are XML based will prove of great utility to the defense sector which is rapidly adopting XML as a military information standard in many large-scale projects. The program transformation and development environment technologies would have dual use in the commercial sector
