An Extensible Framework for Rapid Fuselet Composition

We propose to develop scripting language enhancements to enable the rapid synthesis of publish-subscribe fuselets through a unified framework for subscription and resource discovery based on XPath and XQL extensions, to design and prototype itsimplementation in an extensible manner by mapping onto existing interpreter and runtime infrastructures using a combination of dynamic source-to-source transformation and underlying library extensions, and to design an interactive development environmentfor semi-automatic fuselet generation and monitored execution. The provision of semantically conservative extensions which realize advanced query and discovery capabilities is, we posit, vital to the effective integration of evolving COTS scripting and XMLtechnologies into the next generation of battlefield information systems, and will have broad applicability in the larger arenas of document retrieval and networked computation.A scripting language for the rapid assembly of data fusion processes whosequery 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 environmenttechnologies would have dual use in the commercial sector.
