IBM and Microsoft also
hammering on interoperability"> Last year, in a very public display of Web services interoperability, Bill GatesMicrosofts chairman and chief software architectand Steve Mills, senior vice president of IBMs Software Group, demonstrated interoperability between their systems. IBM is a co-author of the WS-Security specification. IBM and Microsoft had been working independently on solving some of the problems related to Web services security but decided to join forces to "augment" their work, Shewchuk said.Then in a meeting in March of 2002 at the San Francisco airport, IBM and Microsoft engineers met to hash out the core WS-Security specification and to set a roadmap whereby that foundational specification would lead to subsequent ones like WS-Trust and WS-SecureConversation, he said. The date is fresh in Shewchuks mind because not only was the WS-Security specification bornso too was his daughter. "Its really exciting to see the industry as a whole coalesce around this," Shewchuk said. According to a joint white paper from IBM and Microsoft describing the WS-Security specification and security roadmap, "While WS-Security is the cornerstone of this effort, it is only the beginning, and we will cooperate with the industry to produce additional specifications that will deal with policy, trust and privacy issues." "WS-Security is really the linchpin spec to take Web services beyond the basic interchange of information," Shewchuk said. "Ratification of WS-Security is a significant step in addressing one of the most challenging barriers to successful Web services adoption: security," said Schmelzer. "By getting some sense of unity behind these specs, we can expect companies to look more seriously at Web services as a technology they can reliably implement in and between their organizations. Now that WS-Security has passed this milestone, we hope that end-user and vendor companies and the WS-I [Web Services Interoperability Organization] back the spec as a sure thing rather than pitch equivalent alternatives that might slow the adoption of Web services going forward." Said Shewchuk: "If you really need to go beyond this thing being a toy to something that enables business, this is the spec that does that." Meanwhile, in other OASIS news, OASIS announced plans to host a Symposium on Reliable Infrastructures for XML, April 26-27 in New Orleans. In a statement, Chet Ensign, director of architecture at Lexis Publishing Inc. and chair of the Program Committee of the OASIS Technical Advisory Board, said, "Today, many different (and partially interchangeable) technologies are available that propose to increase the reliability of XML-based messaging and networking infrastructure. We define reliable to mean that implementing one or more of these technologies in an infrastructure removes some of the burden of ensuring application integrity from software programmers and architects."
