DMTF Keynote at Policy 2003
Andrea Westerinen, DMTF vice president of technology, has been invited to deliver the keynote address at the Policy 2003 conference in Lake Como, Italy, June 4-6, 2003. Titled "What is Policy? And, What Can It be?", Andrea's presentation will cover her thoughts on what policy actually is, and discuss the confusion surrounding "policy," providing criteria for evaluating a product's claims to policy-based management. DMTF members attending the conference are invited to attend this enlightening discussion, which is part of DMTF's ongoing commitment to international outreach and industry education.

New Sub-Team for Web Services
DMTF has formed a new sub-team in the Interoperability Working Group to advance the organization's Web Services development efforts. Dubbed CIM-SOAP (Common Information Model-Simple Object Access Protocol), the group will define how CIM is used in the Web Services environment. This will help to achieve interoperability between various Web-based enterprise management solutions in the distributed, heterogeneous enterprise. At the June 2003 Global Management Conference, the group's work plan, design architecture, and design concepts will be presented.
"Management and Internet standard technologies are converging. This is the next step in WBEM, building on new Web technologies to unify the management of computing and networking environments," says Tyky Aichelen of IBM, team lead of DMTF's CIM-SOAP group. "SOAP is a central and important protocol in the world of Web Services. It is now at its 1.2 level and is mature for implementation in the production environment. So, the right technical direction is to include it in our work since the goals for CIM and WBEM are to address the multi-protocol environment."
With the new sub-team, DMTF is taking the lead to define how CIM will operate in the Web Services environment. This group will also coordinate with other standards organizations (such as OASIS and the Global Grid Forum) that are working in this space. CIM-SOAP's development builds on several WBEM specifications that have been released in final status - CIM Operations over HTTP v1.1, Representation of CIM in XML v2.1, and CIM DTD v2.1.1. These are acknowledged as taking the first steps in the Web Services arena.
The DMTF sub-team will develop standard and common ways for CIM to interface and co-exist with Web Services using a two-phased approach. The first phase takes a meta-schema-based approach, using the existing WBEM XML tags within a SOAP envelope. The second phase takes a schema-based approach, mapping the CIM classes, properties and methods into an XML Schema and using WSDL (Web Services Definition Language) to access the data. This work will be aligned with the Common Management Model, being proposed at the Global Grid Forum (GGF), and the standards from the Web Services Distributed Management (WSDM) Technical Committee from the Organization for the Advancement of Structured Information Standards (OASIS).
CIM-SOAP meta-schema mappings will be the first deliverables, due to the immediate needs of development organizations. As noted above, the group is also currently working on WSDL representations, and plans to include all relevant standards - such as XML Schemas Definitions (XSD), Universal Description, Discovery, and Integration (UDDI), Transport Layer Security (TLS)/Secure Socket Layer (SSL) Protocol, etc. - in its work.
