Guidelines for Definition of Managed Objects (GDMO) is a set of rules for the description of Managed Objects (MO) and their management. The GDMO guidelines originate from the International Standards Organization (ISO) and are specified in ISO/IEC 10165 and ITU-T X.722.
The GDMO guidelines are a uniform, structured description language used to specify computers and network components and to classifyobjects, describe their behavior, attributes, actions, and lineages. There are certain analogies between Managed Objects and SNMP 's Structures of Management Information (SMI). However, the GMDO format is not derived from Abstract Syntax Notation One (ASN.1), but it uses ASN.1 to define the syntax and encode the attributes.
With consistent application of the GDMO guidelines, programmers can develop applications for the appropriate devices.
