ATO (Modeler Project File) by E2S n.v.
ATO (Analysis and Transformation of Objects) is a Model Driven Architecture environment consisting of an UML modeler driven by a profile. The definition of a profile is the responsibility of the domain specialist, who defines the (development) process and the quality of the development. The application developer then starts the UML modeler with a selected domain profile, which now drives the behavior of the UML modeler. The ATO Profile Editor uses the extension .APF. This file format is classified as Database.
