Implementation issues of a Grid Service Markup Language

To facilitate end users programming in a grid environment, the Vega grid team at Institute of Computing Technology, Chinese Academy of Sciences developed a new high-level language called GSML (Grid Service Markup Language). We discuss the essential issues involved in implementing GSML and associated software tools, and present a prototype implementation with the Java language. The GSML software suite and the implemented prototype are evaluated with real-world applications use cases from the railways industry. The results demonstrate that the GSML software suite can be implemented with high efficiency and relatively small footprint. Furthermore, the GSML tool suite enables users not only to read contents, bust also to write and to operate grid resources, all in a WYSIWYG way.
