4. Device Management Resources
Resource Instance
Attribute
The resource representation of a MO instance
Identify the management functionality it provides
<mgmtObj> 1
moID= “urn:oma:mo:oma-fumo:1.0” 1
originalMO
Referring to the local path of the original MO instance on the remote entity *
<moAttributes> *
Leaf node of the original MO
<parameters>
0-1
Intermediate node of the original MO
originalMO *
<moAttributes> *
< parameters>
The structure can be nested
