MOF, the
Meta-Object Facility, is an
OMG standard for representing
metamodels[?], and manipulating them (through
CORBA). The model (but not the representation) of MOF has some similarities to
UML, but it was designed primarily for use with CORBA, and hence excludes some facilities which are difficult to use in CORBA and includes other CORBA-specific functions. However, UML can be expressed in terms of MOF, which is done to generate
XMI.
