Open Data Element Framework (O-DEF)

The Open Data Element Framework (O-DEF), a standard of The Open Group, enables basic units of data to be classified, so that equivalences and similarities between them can be determined easily. This simplifies the development of interface software and contributes to improved management and organization of data. While it may have other applications, the O-DEF is primarily intended for deployment within extended enterprises, and by groups of collaborating enterprises.

The O-DEF consists of an index and a method for using it to classify data elements. Following this method, a practitioner can tag a data element by assigning a name and numeric identifier to it according to its meaning.

The index is federated. It consists of a core index and a collection of plugins. A plugin can be developed by a standards organization, by a body of specialists in a particular area, by a user enterprise, or by a group of user enterprises.

The core index, and each plugin, is potentially infinitely extensible. The initial version of the index consists of the initial core and three plugins.
