HP WBEM Services Standards
HP WBEM Services implements DMTF WBEM standards. The three
core standards used by HP WBEM Services are:
• A data model, CIM, the Common Information Model standard
The CIM specification is the language and methodology for
describing management data. CIM is a conceptual information model
for describing resources. It is not bound to a particular
implementation, so HP WBEM Services can accept requests from
other platforms.
HP WBEM Services keeps information about its managed resources
in the HP WBEM Services repository, following the Common
Information Model.
For an overview of data representation, see Appendix A. For more
information, see Common Information Model (CIM) Specification,
Version 2.2 (from http://www.dmtf.org/standards/cim).
• An encoding specification, CIM-XML
xmlCIM is the specification for representing CIM in XML.
Requests come from clients to HP WBEM Services as CIM operations
encoded in XML. HP WBEM Services sends the responses to the
clients in XML.
For an overview of XML, see http://www.w3.org/XML for the W3C
Architecture domain’s Extensible Markup Language (XML)
For more information about XML, see DMTF’s Representation of CIM
in XML (from http://www.dmtf.org/standards/published_documents).
Chapter 4 has an example of an xml-encoded request and response.
• A transport mechanism, CIM Operations over HTTP
CIM Operations over HTTP Specification (from
http://www.dmtf.org/standards/ WBEM) specifies the way HTTP
(HyperText Transfer Protocol) is used to transport the CIM
information. This document defines a mapping of CIM operations
onto HTTP that allows implementations of CIM to interoperate in an
open, standardized manner.
