BEGIN:VCALENDAR PRODID:-//hacksw/handcal//NONSGML v1.0//EN METHOD:PUBLISH BEGIN:VEVENT DESCRIPTION:One of the major challenges inhibiting the effective use of distributed resources in government systems stems from the inability to effectively find, understand, and process information across heterogeneous mission domains. The sheer amount of available data and data providers, coupled with the manually-driven, time-intensive processes typically utilized to access these providers, prevent decision makers from receiving the information they need in a timely manner to decide on critical mission threads.nIn order to provide a cross-domain information and resource sharing platform capable of supporting unanticipated users and uses, we developed the Resource Broker Framework (RBF). The RBF leverages semantics-driven federated brokering agents and a modular software component framework for dynamically composing and tasking heterogeneous resources including sensors, processors, databases, networks, and even humans into resilient, mission-oriented workflows.nThis presentation will discuss the concept and architecture of the RBF, specifically focusing on the use of semantics technologies for resource registration, discovery, and planning to form complex workflow specifications. The RBF?s pluggable workflow composition service utilizes a SPARQL-driven, template-based planning approach powered by a generative hierarchical task network planner. Additionally, we will discuss the RBF?s semantic resource registry which provides a semantic interface to XSD-based, non-semantically described resources and facilitates intelligent discovery through resource metadata augmented with OWL markup.
