The Meta Object Facility (MOF) is the OMG’s adopted technology for defining metadata and representing it as CORBA objects. Metadata is a general term for datathat in some sense describes information. The information so described may be information represented in a computer system; e.g. in the form of files, databases, running program instances and so on. Alternatively, the information may be embodied in some system, with the metadata being a description of some aspect of the system such as a part of its design. The MOF supports any kind of metadata that can be described using Object Modeling techniques. This metadata may describe any aspect of a system and the information it contains, and may describe it to any level of detail and rigour depending on the metadata requirements.
