The mission of the DMTF (Distributed Management Task Force) is to lead the development of management standards for distributed desktop, network, enterprise and internet environments. One of the goals of the DMTF is to "Promote interoperability among management solution providers". This tutorial explains one of the ways in which the DMTF is achieving the goal of interoperability, called WBEM. WBEM is the acronym for Web Based Enterprise Management, a set of management and internet standard technologies developed to unify the management of enterprise computing environments. WBEM provides the ability for the industry to deliver a well-integrated set of standard-based management tools leveraging the emerging Web technologies. WBEM has three main components, the Common Information Model (CIM), which provides a common format, language and methodology for collecting and decribing management data.The xmlCIM Encoding Specification defines XML elements, written in Document Type Definition (DTD), which can be used to represent CIM classes and instances. The CIM Operations over HTTP specification defines a mapping of CIM operations onto HTTP that allows implementations of CIM to interoperate in an open, standardized manner and completes the technologies that support WBEM.
