  • [October 30, 2002] XML Wrapper Generator for DB2. IBM alphaWorks has released a graphical XML Wrapper Generator tool "that enables rapid and automatic integration of XML data sources into a DB2 database using the XML Wrapper. This tool loads XML schema files, 'shreds' them to a relational schema, and generates appropriate NICKNAME and VIEW statements. Note: Shredding refers to taking apart an XML document or schema and placing the pieces in a set of tables.) The XML Wrapper Generator is a stand-alone Java application with a graphical interface. Upon loading an XML schema, the tree-structure of this schema can be seen. At the push of a button, the schema is transformed to a set of tables, seen as a second tree-like structure. Arrows pointing from elements of the XML schema to elements of the relational schema show which parts of the XML schema were transformed to which parts of the relational schema. At this point, there is opportunity to modify this relational schema by adding and removing attributes and tables, by changing data types, etc. Once a satisfactory result is obtained, the XML Wrapper Generator automatically generates data definiton statements for DB2. These CREATE NICKNAME... and CREATE VIEW... statements can be excuted in DB2 and thereafter allow users to pose standard SQL queries against any kind of XML document that conforms to the original XML schema... Loading of DTDs is currently not implemented [but the team is] working on it. To convert DTDs into XML schemas (XSDs) in the meantime, try one of the conversion tools.

  • [October 18, 2002] IBM alphaWorks Releases Web Services Outsourcing Manager (WSOM). The Web Services Outsourcing Manager (WSOM) from IBM alphaWorks "is a framework that enables dynamic composition of Web service flow based on customer requirements. The customer requirements are analyzed and optimized to generate an annotation document for business process outsourcing. This service-oriented architecture allows effective searching for appropriate Web services and integration of them into one composite Web service for performing a specific task. Meanwhile, it provides a seamless, integrated framework for composition of template-based business processes and event-driven business processes. The purpose of WSOM is to fully automate the end-to-end composition of business processes by using existing Web services. WSOM bridges the gap between the informal, subjective customer requirements and the objective, machine-readable flow language, such as BPEL4WS, WSFL, and XLANG. WSOM automates the generation of scripts for searching for Web services; and it automates the process of selecting Web services by using a "pluggable" optimization framework. WSOM also monitors and tunes the composed business process so that it adapts to the new requirements at run time... WSOM provides a suite of tools for capturing customer requirements, which could be partially represented in BPEL4WS at abstraction level. Then WSOM binds a set of real Web services to the conceptual Web services that were defined in the business process template to match customer requirements. As a result, the business process constructed by WSOM could be adapted to different Web service flow languages, such as WSFL, BPEL4WS, and so forth. The adaptor in WSOM generates only WSFL in this technology preview; it will support BPEL4WS in the future releases."

  • [October 10, 2002] XML 2002 To Bring Industry and Standards Together. An announcement from IDEAlliance reports that the XML Conference and Exposition 2002 "is expected to attract more than 1,000 IT professionals, including applications engineers, chief information officers, directors of e-business, project managers and team leaders from Fortune 500 corporations as well as small businesses, government agencies and nonprofit organizations." XML 2002 is co-hosted by DISA, OASIS, and W3C. "This year's event is being held December 8-13, 2002 in Baltimore, Maryland at the Baltimore Convention Center... Participants in XML 2002 can take advantage of a variety of learning formats, including technical sessions, keynote addresses, plenary sessions, informal business receptions, discussion groups and social events. This year's event offers attendees its most comprehensive and focused program to date, with more than 100 sessions given by professionals from around the globe. The Exposition will feature more than 50 providers of XML-based products and services offering hands-on demonstrations and displays December 10 through 12. Attendees will have the opportunity to see in-depth demonstrations of the newest products and technologies. Several new product announcements are expected to be made at the show. In addition, a new technology arena will showcase pre-released software innovations." See the announcement: "XML 2002 to Bring Industry and Standards Together. Leading IT Organizations and Consortia to Participate and Collaborate on XML Conference and Exposition 2002 Program."

  • [October 07, 2002] SAP Reports Successful Use of UDDI Version 2.0 in UBR. A posting from Claus von Riegen (XML Standards Architect SAP AG) announces SAP's "successful implementation and usage of UDDI Version 2.0 in its node of the UDDI Business Registry." This implementation is said to support the UDDI Specification TC's goal of proposing UDDI Version 2.0 as an OASIS Standard. From the main page: "The SAP Universal Description, Discovery and Integration Business Registry is a database that facilitates the creation of open yet fully integrated collaborative business scenarios. It is part of the UDDI industry initiative to create a platform-independent, open framework for describing services, discovering businesses, and integrating business services using the Internet. The Registry contains descriptions of Businesses, Web Services and other Entities and can be used by anyone who wants to make information available about one or more Businesses and their Service Offerings." See: "Universal Description, Discovery, and Integration (UDDI)."

  • [October 04, 2002] Major New Release of XML Schema Validator (XSV). A posting from Henry S. Thompson announces a "Major New Release of XSV" which reorganizes the code to make it PPC (Python Polically Correct) and adds new functionality. XSV (XML Schema Validator) is an open source GPLed work-in-progress attempt at a conformant schema-aware processor, as defined by XML Schema Part 1: Structures, May 2, 2001 (REC) version. Henry says: "New functionality includes command-line settable optional invocation control of top-level element name and/or type, partial support for the 'pattern' facet. The status page provides more details, including information on the Win32 installer and running the sources -- made easier now, because there are RPMs for the underlying PyLTXML stuff... Since this is a major re-org, there's obviously a bigger chance than usual of bugs lurking, despite moderately careful regression testing -- please let me know ASAP of anything that stops working..."
