It is common for information exchange between heterogeneous systems to be syntactically correct but fail to achieve its intended purpose due to semantic mismatches. NATO research group IST-094 is developing a framework to facilitate semantic interoperability. We will show a live demonstration of one possible approach to implementing a message translation broker, following the Semantic Interoperability Framework phase structure (i.e., preparatory, configuration, and operational phases). The broker uses a combination of OWL, SWRL, Prolog, Java, XSLT, and Javascript. What follows is an extended abstract of the translation broker demonstration and the introductory presentation that will describe its technical foundations.
