For WS-Management connections, the client must also specify a resource URI when accessing CIM objects. The URI represents an XML namespace associated with the schema definition.

The choice of URI depends on the class name of the CIM object. The prefix of the class name determines which URI the client must use. Table 2-3 shows which URI to use for each supported class name prefix.

Class Name Prefix Resource URI (Namespace only - link will not work in a browser)
VMware_ http://schemas.vmware.com/wbem/wscim/1/cim-schema/2/
OMC_ http://schema.omc-project.org/wbem/wscim/1/cim-schema/2/
CIM_ http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/

Note that the URIs given above do not resolve to a web page location. Although they look like a web address, they just represent a section of the CIM XML schema that you need to specify.

Example:

xmlns="http://schemas.vmware.com/wbem/wscim/1/cim-schema/2/"

See http://www.w3schools.com/schema/schema_example.asp for more information about XML namespaces.
