Euterpe, a Task Analysis tool
Euterpe is a Task Analysis tool developed at the Vrije Universiteit Amsterdam. It is based on an ontology for describing the task world in a structured way. The theory behind it is based of GTA. Euterpe helps to build task trees, object hierarchies and other important concepts such as event and roles. Templates allow detailed information to be specified and multimedia can be attached to concepts to clarify their nature. Documentation can be generated on paper and as HTML pages.
