The AAF Low-Level Container Specification describes how each object is stored on disk.

There are two major parts to AAF: the AAF Object Specification and the AAF Software Development Kit ( SDK ) Reference Implementation

The AAF Object Specification defines a structured container for storing essence data and metadata using an object-oriented model.

The AAF Object Specification defines the logical contents of the objects and the rules for how the objects relate to each other.

* The AAF Object Specification, which defines the way AAF stores metadata and essence

* The AAF API Specification, which defines how software engineers can write applications

While MXF uses a KLV ( Key Length Value ) format for storage, AAF uses the Microsoft Structured Storage system.

All types of media file formats, from QuickTime DV MPEG AES / EBU MXF through Serial Digital Interface, OMFi, AAF, OpenEXR, to 4k DPX files are supported.

The Advanced Authoring Format ( AAF ) is a professional file interchange format designed for the video post production and authoring environment.

The metadata in an AAF file can provide the

information needed to combine and modify the sections of essence data in the AAF file to produce a complete multimedia program.

Both XML and the Advanced Authoring Format ( AAF ) are relatively advanced file formats that can contain sophisticated EDLs.

By January 1945 only 50 % of AAF WACs held traditional assignments such as file clerk, typist, and stenographer.

MXF was developed to carry a subset of the Advanced Authoring Format ( AAF ) data model, under a policy known as the Zero Divergence Directive ( ZDD ).

After a trip to South America in January 1946, in which he developed a heart arrhythmia severe enough to cancel the remainder of the trip, Arnold left active duty in the AAF on February 28, 1946, ( his official date of retirement was June 30, 1946 ).

He divided the Army of the United States into three autonomous components to conduct the operations of the War Department: the Army Ground Forces trained land troops ; the Army Air Forces ( AAF ) developed an independent air arm ; and the Services of Supply ( later Army Service Forces ) directed administrative and logistical operations.

MXF was developed to be essentially a subset of the AAF data model, under the Zero Divergence Directive ( ZDD ) policy.

The AAF had developed an excess of pilots and pilot candidates.

The AAF was very significant before and during the 1980s but by the time of the U. S. invasion of Afghanistan in 2001, the number of aircraft available was minimal.

The AAF was reduced to a very small force while the country was torn by civil war.

Las Vegas AAF was re-activated on 30 August 1947 by Air Training Command as a subinstallation of Mather Army Airfield, California under the ATC Flying Training Division.

The National Museum of the United States Air Force in Dayton, Ohio, has an extensive display dedicated to the AVG, including an A-2 jacket worn by an AVG pilot in China, a banner presented to the AAF by the Chinese government, and a P-40E.

Yuma AAF was a single-engine flight training school, operated by the Army Air Forces Flying Training Command, West Coast Training Center, with flying training beginning in January 1943.

On 5 July 1942, during World War II, the airport was commandeered by the United States Army Air Forces and used as a contract primary pilot training airfield under the AAF Gulf Coast Training Center ( later Central Flying Training Command ).

With the bombing of Pearl Harbor on December 7, 1941, the need for bombardiers was evident, soon after an announcement was made by Lieutenant Colonel Isaiah Davies, Commanding Officer of Midland Army Air Field ( MAAF ), that Midland AAF would be used exclusively to train bombardiers in the AT-11 Kansan for eventual assignment to bomber aircraft such as the B-17 Flying Fortress, B-24 Liberator, B-25 Mitchell, B-26 Marauder and B-29 Superfortress.

The AAF was created by the Advanced Media Workflow Association ( AMWA ).

In AAF these kinds of data are called essence data, because they are the essential data within a multimedia program that can be perceived directly by the audience

For example, AAF has been adopted by the DoD / IC Motion Imagery Standards Board ( MISB ) for their Aerial Surveillance and Photogrammetry Applications standard ( ASPA ).

* The AAF Example files created by working AAF implementations

AAF was originally created by the Advanced Media Workflow Association ( AMWA ), formerly the AAF Association Inc., a broadly based trade association created to promote the development and adoption of AAF, MXF and SOA technology in media workflows.

At MacDill, Eighth Air Force headquarters were manned chiefly by personnel from the 58th Bombardment Wing, Very Heavy, stationed at Fort Worth AAF, Texas.

Between Marfa AAF and its satellite fields — each constantly patrolled by sentries — they consider it unlikely that any actual phenomena would have remained unobserved and unmentioned.

The task facing the Tenth Air Force of creating an airlift was daunting at minimum, emphasizing all that the Army Air Forces lacked in April 1942: no units tasked for moving cargo, no experience in organized airlift by the AAF or its predecessor Air Corps, and no airfields for basing units.

On 11 October 1946, the 4156th AAF Base Unit was ordered to cease operations by the 30th of the month.

On May 1, 1944, the 335th was replaced by the 331st Army Air Force ( AAF ) Base Unit as the OTU, being subsequently replaced by the 2621st AAF Base Unit on December 1, 1945.

On 15 August 1947, the 1st Fighter Wing was activated as part of AAF Regulation 20-15, " Reorganization of AAF Base Units and Installations ," on 27 June 1947.

" MO " on fuselsage signififies Moody AAF aircraft.

In August 1946, the AAF inactivated Moody placing it on standby status.

With the end of World War II, Columbus AAF was first placed on " reduced activity status ", and was inactivated on August 15, 1946.

Clovis AAF was placed on temporarily inactive status 28 May 1947.

Clovis AAF was renamed " Clovis Air Force Base " on 13 January 1948.

The RAF and American AAF dropped two million tons of high explosives bombs on 60 German cities, killing more than half a million citizens ( many of them prisoners forced to work in German munitions factories ), and leaving 80, 000 airmen dead.

The base was officially activated as Las Vegas AAF on 20 December 1941.

Acting on an executive order from Roosevelt, the War Department granted the AAF full autonomy, equal to and entirely separate from the Army Ground Forces and Services of Supply.

In 1945, captured German aircraft brought from Europe on the HMS Reaper for evaluation under Operation Lusty were off-loaded at Newark AAF and then flown or shipped to Freeman Field, Indiana or Naval Air Station Patuxent River, Maryland.

Twentieth Air Force commander and AAF Commanding General Henry H. Arnold grew impatient with a lack of discernible results, and replaced General Haywood S. Hansell with General Curtis LeMay as commander of XXI Bomber Command on January 21, 1945.

Although destroyed as a unit, the group remained on the list of active AAF units until the end of the war.

: Activated at Grand Island AAF, Nebraska on 4 August 1946

: Activated at Clovis AAF, New Mexico on 4 August 1946

: Activated at MacDill AAF, Florida on 4 August 1946

: Reassigned to MacDill AAF, Florida on 17 April 1946

* Established as 23d Army Air Forces ( AAF ) Ferrying Wing on 12 June 1942

In 1909 Dobbs became president of the Associated Advertising Clubs of America, now the American Advertising Federation ( AAF ), and began to make speeches on the subject.
