Prof. 2. Prof. 3. Prof. 4. Prof. Date of Defense Availability Abstract This document describes about extending the functionality of a Web services based logger system using SOAP Message Transmission Optimization (MTOM) recommendation from W3C. MTOM uses XML binary optimized packaging (XOP) recommendation from W3C to provide an optimized XML serialization for binary data in XML. This work adds binary transport and locale specific translation (localization) feature for the binary log messages stored in the log repository.
