Towards an Event Modeling Language

Object-oriented programming owes part of its popularity to Booch's notation 2], Rumbaugh's OMT 7], and UML 8]. These notations allow object oriented designs to be expressed graphically and furthermore have enabled the development of case tools for object oriented languages. The lack of a suitable high level graphical notation has been identiied as one of the factors discouraging the uptake of functional programming and in particular the language Erlang 1]. This paper represents a rst step in designing a graphical modeling language for functional programming that encourages sound programming practices. The initial target language is Erlang but it is hoped that the notation can be extended to other functional languages.
