Page "IDEF0" Paragraph 11

In 1983, the U. S. Air Force Integrated Information Support System program enhanced the IDEF1 information modeling technique to form IDEF1X ( IDEF1 Extended ), a semantic data modeling technique.

By the 1990s, IDEF0 and IDEF1X techniques are widely used in the government, industrial and commercial sectors, supporting modeling efforts for a wide range of enterprises and application domains.

In 1991 the National Institute of Standards and Technology ( NIST ) received support from the U. S. Department of Defense, Office of Corporate Information Management ( DoD / CIM ), to develop one or more Federal Information Processing Standard ( FIPS ) for modeling techniques.

The techniques selected were IDEF0 for function modeling and IDEF1X for information modeling.

These FIPS documents are based on the IDEF manuals published by the U. S. Air Force in the early 1980s.
