 | Level: Advanced Contributors: IBM 01 Apr 2005 This document describes a proposal for how to represent Common Information Model (CIM)-modeled resources as Web Services Distributed Management (WSDM) Manageable Resource Web services. It describes how to represent and access the content of the CIM model using Web services, WS-Resource Framework, WS-Notification specifications, and WSDM. This draft proposal has been submitted for consideration by the Distributed Management Task Force (DFTM).
This specification is a proposal for a CIM mapping to WSDM developed by the following members of WS-CIM: Computer Associates, Cisco, HP and IBM. This proposal has been submitted for consideration by the DMTF Web-Based Enterprise Management (WBEM) Infrastructure and Protocols Working Group's WS-CIM Subgroup (WS-CIM group). This document describes a mapping from the CIM resource model and related operations to Web services using Web Services Distributed Management: Management Using Web Services (WSDM-MUWS) and its underlying specifications. The mappings are described in general terms as well as through the use of an example that is applied throughout the document to illustrate the effect of the mapping on a simple set of CIM classes. In its current wording, this document does not intend to be a normative specification of the mapping. It is a collection of technical decisions that provide the content for a normative prescription of the mapping. Furthermore, not all aspects of the mapping are currently covered in the document. Section 18 Future steps lists known areas into which the mapping needs to be extended. The definition of the normative prescription is considered to be the task of the WS-CIM group.
