Guidelines for the Definition of Managed Objects
The Guidelines for the Definition of Managed Objects (GDMO) is a specification for defining managed objects of interest to the Telecommunications Management Network for use in CMIP.
GDMO is similar to the Structure of Management Information for defining a management information base for SNMP. For example, both represent a hierarchy of managed objects and use ASN.1 for syntax.
GDMO is defined in ISO/IEC 10165 and ITU-T X.722.
