DRAKON

DRAKON is an algorithmic visual programming language developed within the Buran space project following ergonomic design principles. The language provides a uniform way to represent flowcharts of any complexity that are easy to read and understand.

The DRAKON Editor, which was released in September 2011, is an implementation of the language available in the public domain. It can be used for creating documentation, or for creating visual programs that can be converted to source code in other languages.

The development of DRAKON started in 1986 and was directed by Vladimir Parondzhanov with the participation of Russian Federal Space Agency (Academician Pilyugin Center, Moscow) and Russian Academy of Sciences (Keldysh Institute of Applied Mathematics). The language was constructed by formalization, ergonomization and nonclassical structurization of flowcharts described in the ISO 5807-85 standard and Russian standard «Гост 19.701-90» and for the development of real time programs.

The goal was to replace specialised languages PROL2 (ПРОЛ2) (assigned for developing onboard complex software for embedded computer system Biser-4 (Бисер-4) on board of Buran), DIPOL (ДИПОЛЬ) (assigned for developing software for ground maintenance computer system of Buran) and LAKS (ЛАКС) (assigned for modelling) used in the Buran project with one universal programming language.

The work was finished in 1996 (3 years after the Buran project was officially closed), when an automated CASE programming system called "Grafit-Floks" was developed.
