Performance and Usability Enhancements to the Scripted BML Server

The approach to defining a coalition Battle Management Language (BML) now being pursued by SISO requires mapping of BML into a JC3IEDM database, which is accessed via a Web service. In previous SIW papers we have reported on a new approach to implementing such a Web service, based on the notion of an interpreter module. This scripting engine takes as its input the schema of the Web service and a script, coded in XML, that defines the mappings concisely. The Scripted BML Server (SBML), which is available as open source software, has the virtues that it is quicker and easier to change than a hard-coded service and also requires a lower level of expertise for development, once the interpreter has been completed. Previous SIW papers have described the development of the SBML concept and its various enhanced capabilities. This paper describes recent enhancements including BML namespaces, BML message push/pull logging/replay, threaded and parallel operation for improved performance, a Condensed Scripting Language (CSL), and a NATO OPORD schema.
