Method for transforming from BPEL to WSCI and the Transformer

摘要

The present invention relates to a BPEL-to-WSCI conversion method and a converter for generating a WSCI interface corresponding to each BPEL business process for mutual conversion between WSCI and BPEL, which are two standard specifications of a web service composition technology.;The BPEL-to-WSCI converter of the present invention comprises: a simple activity processor that performs a transformation on basic unit elements of a web service behavior; A structured activity processor that performs transformations on elements that structure a plurality of simple activities; A source / target processor that performs a transformation on the ordered source / target elements in the parallel structure between each activity; An execution environment handler that converts link and scope elements within the structured activity; And a process generator for generating a process of the WSCI corresponding to the scope describing the execution environment of the BPEL.
