US Defense Department Pursues Systems Interoperability with XML
The Cursor on Target ) XML schema developed by and the U.S. Air Force has proven successful in recent urban warfare exercises. CoT has become a de facto standard for tactical systems data integration but Mike Gorman of Whitemarsh Systems warns of deficiencies with this approach to data management. In a recent analysis about the development of a Defense metadata registry, Gorman warned the Tag and Post method, using published schemas such as Cursor on Target, is inconsistent with the "collective wisdom" of DBMS vendors and the data management community. He advocates the more formal Data Standardization Approach used by the U.S. Army Net-centric Data Management Program.

World Wide Web Architecture Volume One is W3C Recommendation
The W3C specification for the web architecture describes "cored design components of the web". The specification describes protocols, components, resource state, and formats for data. The next volume will focus on mobile web applications, web services and the semantic web.

"Software Trends: Marrying SQL, XML, Web Services and Grid Computing" was a panel discussion recorded at Software Development 2004. This was one of several video and audio programs we recorded during the conference.
"Web Services at the San Diego Supercomputer Center" includes audio and video programs about service-oriented architectures, XML acceleration, federated identities and WS-Security.
"Technology Trends" covers servers, web services, grid computing, data models, price-performance, Linux, open source, .NET, J2EE, data mining, vector databases, ubiquitous connectivity, and bio-electrical links. This is an expanded version of the keynote at Enterprise Data Forum in Philadelphia.
"XQuery and SQL: Vive la Différence" (DB2 magazine) discusses XQuery, SQL and the XQuery API for Java (XQJ).

Ontologies, Agents, Declarative Languages and Semantic Web Services
by Ken North
In June 2000, Andrew Layman unveiled Microsoft's concept of Web services during a software conference in New York. Within a few months, IBM, Microsoft, Ariba and their partners announced the rollout of Universal Description, Discovery and Integration (UDDI). The UDDI registry is a solution for discovery of services. It involves distributed, replicated databases that are accessible using APIs for publishing and finding services.
One of the goals of UDDI was to provide a registry for e-business, but private UDDI registries found their way into organizations as an integration tool. Some people expressed reservations about whether a programmatic API-based solution, such as UDDI, was the best approach to service discovery. Researchers, developers and analysts considered alternatives such as declarative languages and automatic discovery of services.
During this period, Tim Berners-Lee drew much attention to the semantic web, which caused a surge of interest in semantics research and development of ontologies. Some persons in the web community point to ontologies and languages such as XL and Water as being key ingredients for advancing the state of the art and moving web services to critical mass.

Searching for Services on the Semantic Web Using Process Ontologies
Mark Klein (Massachusetts Institute of Technology), Abraham Bernstein (New York University)
The authors suggest current information retrieval techniques are optimized for text, not services. Frame based approaches increase precision but retrieve only perfect match. This paper describes an ontology-based approach as a better alternative for searching for services.
Semantic Web Service Architecture — Evolving Web Service Standards toward the Semantic Web
Tanja Sollazzo, Siegfried Handschuh, Steffen Staab, Martin Frank (Universität Karlsruhe)
The authors suggest an evolution from the current model for web services to a semantic web service model is attainable. This paper describes SWOBIS, an ontology-based registry for use with the Semantic Web.
Semantic Web Services
Sheila A. McIlraith, Tran Cao Son, Honglei Zeng (Stanford University)
The authors propose a semantic markup of web services that permits the construction of a distributed knowledge base. This provides a vehicle for agents to reason about web services and perform automatic discovery and execution of services.
Collaboration Over the Internet
XML-based messaging provides the plumbing for the development and deployment of web services. Specifications from the World Wide Web Consortium (W3C), OASIS, Web Services Interoperability (WS-I) provide conformance guidelines for the creation of cooperative, interoperable services.
Grid technologies allow us to partition problems and apply massive computing power to their solution.
