Extending rich semantics in an architecture for data sharing and collaboration for counter terrorism

This paper presents the most recent experimental results of ongoing efforts to architect and prototype an end-to-end system. The application of simple XML-based specifications for messages is presented in the context of creating a light-weight and flexible means to bring content into analytical systems. The use of stateful and persistent styles of building Web services using a representational state transfer (REST-ful) model is presented as a means for providing publication and subscription style services. Finally, the spectrum of well-described information to constrained operational semantics is explored within the context of requirements to support services for collaborative analysis; the preliminary results strongly suggest well-described information with flexibly defined constraints is well-suited for services to enable analytical processes for counter terrorism data sharing and collaboration.
