Monday, August 26, 2002EAI Journal: The Web Services Scandal; How Data Semantics Have Been Overlooked in Integration Solutions.
"At best, the lessons we’ve learned from industry’s work with EDI have shown us that:

Friday, August 09, 2002IBM was quick to release implementation of BPEL4WS called BPWS4J the very same day specification was published (which is today, August 9). More info from one of the co-authors, Sanjiva Weerawarana: "BPWS4J consists of two parts: an engine and an editor. The BPWS4J Engine is an all-Java implementation of BPEL4WS that runs in a
servlet container. The BPWS4J Editor is an Eclipse plugin that can be used with Eclipse v2.0+ (http://www.eclipse.org/)." Posted to services, xml @ 4:15:25 PM ( comments)
As it turns out, Business Process Execution Language for Web Services (BPEL4WS or WS-BPEL) represents the merging of WSFL and XLANG specs. Wow! Two other specs. WS-Coordination: Describes an extensible framework for providing protocols that coordinate the actions of distributed applications. WS-Transaction: Describes coordination types that are used with the extensible coordination framework described in WS-Coordination. Posted to services, xml @ 4:12:08 PM ( comments)
CNET: Tech giants back new Web services. "Microsoft, IBM and BEA Systems plan to announce new specifications Monday that the companies hope will help drive adoption of Web services. The first specification--called Business Process Execution Language for Web Services--is a programming language for defining how to combine Web services to accomplish a particular task. Web services are emerging methods of writing software that allows businesses to interact via the Internet. The second, WS-Coordination, describes how individual Web services within that task interact. A software programmer, for example, can stitch together Web services into a sequence of operations to accomplish a particular task. The third specification, called WS-Transaction, is used to ensure that transactions all complete successfully or fail as a group." I'm wondering what are the relationships between newly created BPEL4WS, and XLANG (Microsoft), WSFL/WSXL (IBM) and WSCL (HP) specs? Posted to services, xml @ 2:19:24 PM ( comments)
Sunday, July 21, 2002Sam Ruby: REST + SOAP. "In reality, there aren't two sides. There are at least four: Everything is a resource. Everything is a get. Everything is a message. Everything is a procedure." I think Sam again got it right. It's not about on what side you are, it's about how you can productively use both approaches.

Steve Pepper: The TAO of Topic Maps. "The generality and expressive power of the topic map model bring with it other advantages that go far beyond those traditionally associated with indexes. The close similarity to semantic nets gives an idea of how topic maps, even without any occurrences connecting them to an information pool, can become valuable resources in their own right. This in turn opens up new business opportunities for creating and selling “portable topic maps” that can be overlaid on multiple information pools. For traditional commercial publishers, producing well-crafted topic maps could be a new way of leveraging their existing knowledge and experience and combating the threat to their existence posed by the vast amounts of information now available for free."

Word 11, XML, and the universal canvas. "The endgame is what Microsoft has called the universal canvas. In the long run, that means migrating software to a common storage model. That won't happen any time soon, but there's a big near-term opportunity to leverage XML as an exchange format much more aggressively. I'd like to see that happen across the suite of Microsoft's clients by the time Office 11 ships. I'm not holding my breath, though." [Jon's Radio] Me neither. Although I'd like it to happen across many different apps and clients. Posted to xml @ 4:27:32 PM ( comments)
Monday, July 08, 2002Eric van der Vlist: Cataloging XML Vocabularies. "I've been involved recently in many discussions and projects oriented around a simple and common question: "how do I create an XML vocabulary?" The formulation was often different -- "how do I create a namespace?" or "how do I publish an XML schema?" -- but the central issue was always about what infrastructure to create and which methods should be used to advertise the newly created vocabulary."

Friday, July 05, 2002ActiveState just released the beta of Visual XSLT 1.5. It's got a couple of neat new features like support for .NET extension objects and an XPath expression evaluator. Sign up for the beta here. [Peter Drayton's Radio Weblog] Posted to xml @ 2:03:49 PM ( comments)
