TAO can be used in all contexts where annotated tree structures are the common denominator. In particular it can serve as or be used to build:
TAO grows out of a broader vision to find a Universal Tree Annotation Syntax (UTAS). It is an attempt to bring a common language to all domains with the hope that unification and simplification at a very basic level will reduce complexity, duplication, and coupling, and will propagate and add up to tremendous improvements across different aspects of both the digital and the real world.
