In one implementation, we describe the semantics of skeleton joints of the avatar to be animated as a mapping to a highly-detailed skeleton model containing most or all of the joints and bones of human anatomy (the "reference skeleton"). Such a reference skeleton (e.g., the "LOA-4" version of the Web3D humanoid skeleton model) features detailed models of the hand and foot phalanges and joints for every vertebra of the spine. Owing to the level of detail of the reference skeleton, each joint of a user-defined animation skeleton can be mapped to one of the joints of the reference skeleton.

Such semantics can be used in implementing some features of a virtual world platform, for example, in automated action or gesture recognition.
