Remote Batch Invocation for Web Services Document-Oriented Web Services With Object-Oriented Interfaces

Free registration required

Executive Summary

The Web Service Description Language defines a service as a procedure whose inputs and outputs are structured XML data values, sometimes called documents. In this paper the authors argue that document-oriented interfaces can be viewed as batches of calls to finer-grained procedural interfaces. Turning this correspondence around, the authors shows that flexible documents can be specified by converting a block of fine-grained invocations into a batch document. Batch blocks can also include conditionals and loops.
