In BPEL4WS a business process defines how to coordinate the interactions between a process instance and its partners. All the partners that interact as part of the process are modeled as WSDL services. A BPEL4WS process also is modeled using the WSDL model of separation between the abstract message contents used by the business process and deployment information (messages and PortType versus binding and address information). Typically a BPEL4WS process uses some .wsdl and .bpel files. BizTalk Server 2004 provides support for BPEL4WS 1.1 fundamentally using the BPEL Import-Export wizards. Using these tools we can export some types of orchestrations to BPEL4WS (.bpel and .wsdl file are generated) and also import .bpel and .wsdl files to create a BizTalk orchestration.

BPEL4WS import wizard is one of the tools to consider when we want to think in contract-first in BizTalk Server 2004. This tool makes possible to design the description of our process facilitating the interoperability with heterogeneous systems.
This is an interesting take on contract-first from a BizTalk mindset, and notice it goes even further, to the level of business process design.
