	Business Process with BPEL4WS: Understanding BPEL4WS, Part 1
		BPEL4WS combines the best of both WSFL (support for graph oriented processes) and XLANG (structural constructs for processes) into one cohesive package that supports the implementation of any kind of business process in a very natural manner.
		BPEL4WS only uses and supports input-only and input-output (request-response) operations of WSDL; output-only (notification) and output-input (solicit-response) operations are not required nor supported.
		BPEL4WS allows you to recursively combine the structured activities to express arbitrarily complex algorithms that represent the implementation of the service.

		BPEL4WS and WSDL may be used to describe service types, protocols that are supported and other deployment details.
		BPEL4WS is intended to provide for more automated Web services, which is considered crucial to spread the use of Web services for back-end integration for applications such as e-commerce.

	Service-Oriented Composition in BPEL4WS
		In the BPEL4WS composition model recursive composition is enabled by two ``input'' activities: a receive activity, representing a step in the execution where the flow waits to receive an incoming message, and an optional matching reply activity, representing the return message of a synchronous request-response operation.
		Note that BPEL4WS allows the definition of multiple ``receive'' activities corresponding to the same operation and partner, effectively allowing the same operation to be invoked by the same party at different points in the composition's execution.
		BPEL4WS exploits this common pattern to map messages to choreography instances without requiring the exchange of an instance ID of any sort - while that approach would solve the problem, it adds an extra component to data exchanges that would not otherwise be needed.

	Web services standards: the battle continues - TechUpdate - ZDNet (Site not responding. Last check: 2007-10-23)
		There is no question that BPEL4WS is a standard; the question is whether it will emerge as the dominant, de facto standard to describe and share processes within and among enterprises, said Borges.
		He believes BPEL4WS is very likely to succeed as the de facto standard and will have a significant impact on the redesign and deployment of processes within the enterprise, because of the disparate, but quite substantial, efforts around XLANG and WSFL.
		For example, BPEL4WS is in direct competition with WSCI, pitting IBM and Microsoft against Sun and the rest of the pack.

	Cover Pages: Web Services Specifications for Business Transactions and Process Automation.
		BPEL4WS allows companies to describe business processes that include multiple Web services and standardize message exchange internally and between partners.
		Once the business process and the connections with customers, partners and internal entities are defined using BPEL4WS, the next step is to coordinate the various activities that occur within a business process, in order and at the right time for completion.
		We anticipate a number of extensions to the feature set of BPEL4WS that are discussed briefly at the end of the document.

	Enterprise Software / BPEL4WS vs. WSCI - Tech Update - ZDNet (Site not responding. Last check: 2007-10-23)
		Although it is completely proprietary and hasn't even been submitted to a standards-setting body, all three companies already have plans to support the specification in their solutions as though it were a standard.
		Unlike BPEL4WS, WSCI has taken the first step towards standardization through a submission to the World Wide Web Consortium (W3C) by BPMI.org (which also developed an alternative to BPEL4WS called BPML), Commerce One, Fujitsu Limited, Intalio, IONA, Oracle Corporation, SAP AG, SeeBeyond Technology Corporation, Sun Microsystems, and strange as it may seem, BPEL4WS co-author BEA.
		Let's suppose that BPEL4WS becomes the de facto standard, by virtue of BEA's, Microsoft's, and IBM's support for BPEL4WS in their application servers (which happen to be the application server market's three leading products).

		The victory of BPEL4WS was pretty much ordained in a world where bigger is better and market share has a higher rating than quality technology.
		Either we complain and say our stuff is better or we say 'Guess what, we'll ride on their coattails and leverage their marketing ability and momentum because, at the end of the day, their work is similar to what we've done.
		However, issues with the lack of distributed processing capability in BPEL4WS may soon be moot: According to Intalio's Ghalimi, BPMI.org and ''its key contributors for BPML are working with IBM and Microsoft to add distributed transactions to BPEL 1.2.

	ECO to BPEL4WS
		BPEL4WS stands for Business Process Execution Language for Web Services and it provides the specification of business processes and business interaction protocols.
		Using Web Services in BPEL4WS to pass commands to the devices will be effective and convenient for those users who are familiar with web services protocols and BPEL4WS standards.
		Recognizing the need to translate Eco into BPEL4WS document accurately, this research aims to develop the translator part, which takes the Eco command as its input and translates the Eco command into high-level workflow model in the form of BPEL4WS document.

		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).
		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.

	WfMC Heralds BPEL4WS Standards
		The recently announced Business Process Execution Language for Web Services (BPEL4WS) is a platform for executing business processes so that they can be more easily reused and integrated with other processes.
		The first review of BPEL4WS suggests that the proposal is compatible with IBM and Microsoft products and therefore the proposed standard may receive de-facto support through adoption of these vendors' products.
		It is also apparent that almost all the features of BPEL4WS are already represented in the WfMC XPDL specification.

	BPEL4WS submitted to OASIS Standards Body
		BPEL4WS (and other flow abstractions) are driven by the need to coordinate asynchronous message exchanges across services distributed over the net.
		The main problem is that BPEL4WS proponents are trying to standardize the language using their financial power, killing possible alternatives right away, without giving anybody a chance to evaluate various ideas in real life applications.
		Right now, WSBPEL (it is no longer called BPEL4WS) is a proposed specification; it is an agglomeration of reasonably good ideas that is going in front of a committee of technology and industry experts for validation, modification, and extension.

		It is explicitly not a goal of the TC to specify bindings to specific hardware/software platforms and other mechanisms required for a complete runtime environment for process implementation.
