Abstract

Continuous process improvement (CPI) may require a BPEL process to be split amongst different participants. In this paper, we enable splitting standard BPEL - without any extensions or new middleware. We present a solution that uses a BPEL process, partition information, and results of data analysis to produce a BPEL process for each participant. The collective behavior of these participant processes recreates the control and data flow of the non-split process. Previous work presented process splitting using a variant of BPEL where data flow is modeled explicitly using ‘data links’. We reuse the control flow aspect from that work, focusing in this paper on maintaining the data dependencies in standard BPEL.
