Oracle released its BPA Suite, which is based on ARIS.
Now there is the first book on the market, talking about the round trip from BPMN to BPEL and back:
Its cover states:
This book is for CIOs, executives, SOA project managers, business
process analysts, BPM and SOA architects, who are responsible for
improving the efficiency of business processes through IT, or for
designing SOA. It provides a high-level coverage of business process
modeling, but it also gives practical development examples on how to
move from model to execution. We expect the readers to be familiar with
the basics of SOA.
The examples provided are not detailed enough for really start developing but this book was not written for developers..
