Common Object Request Broker Architecture (CORBA) is based in an architecture model distribution for heterogeneous environments.
It was proposed by the Object Management Group (OMG).
It is based on the communication protocol GIOP (General InterORB Protocol).
Its language for interface specification is IDL (Interface Description Language).
It is a type of middleware.
GNOME uses CORBA.
MOF
Meta-Object Facility (MOF) is a standard for model-driven engineering. Its purpose is to provide a type system for entities in the CORBA architecture and a set of interfaces through which those types can be created and manipulated.
It was issued by the Open Management Group (OMG).
MOF is designed as a four-layered architecture.
MOF models can be converted to a file by applying the XMI (ISO/IEC 19503) specification. XMI is an XML-based exchange format for models.
As of 2024, its latest version is MOF 2.4.2, issued in 2014.
