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.
