This paper assesses the impact of the Choreographic Language Agent and the Digital Dance Archives on dance ontology. Enhanced visualisation - afforded by digital technology - impacts on the essential ontological features of dance, such as ephememerality and the human body. Referring to the work of Nelson Goodman (1968) and Martin Heidegger (1977), I discuss the significance of creative programming for dance, asking what such tools reveal about the ontology of the form and existing concepts of movement, notation and embodiment.
