2.2 About the WBEM Initiative
SMI-S is based on the Web-Based Enterprise Management (WBEM) Initiative, which is defined
by the Distributed Management Task Force (DMTF). WBEM is a set of management and
Internet standard technologies developed to unify the management of distributed computing
environments.
The DMTF has developed the following core set of standards that make up WBEM:
Table 2-1. Core Standards for WBEM Initiative
Standard Description
The Common Information Model
(CIM) standard
The CIM standard is the data model for WBEM. CIM provides
a conceptual framework for describing management data
for systems, networks, applications and services, and allows
for vendor extensions. SMI-S uses CIM to model those objects
and relationships that comprise a SAN.
CIM-XML CIM-XML is a method of exchanging CIM management data.
CIM-XML uses an xmlCIM payload and HTTP(s) as the
transport mechanism.
This protocol is defined by the following specifications:
 Specification for the Representation of CIM in XML -
Defines a standard for the representation of Common
Information Model (CIM) elements and messages in XML,
written in Document Type Definition (DTD).
 CIM Operations over HTTP - Defines a mapping of CIM
Messages onto HTTP that allows implementations of CIM to
interoperate in an open, standardized manner. It utilizes
the CIM XML DTD that defines the XML Schema for CIM
objects and messages.
WBEM Discovery using Service
Location Protocol (SLP)
WBEM Discovery using SLP is a method for applications to
identify WBEM-based management systems. For more
information regarding WBEM and CIM, refer to the DMTF
