Graphical diagrams are the main modelling constructs offered by the popular modelling language UML. Because textual representations of models also have their benefits, we investigated the integration of textual and graphical modelling languages, by comparing two approaches. One approach uses grammarware and the other uses modelware. As a case study, we implemented two versions of a textual alternative for Activity Diagrams, which is an example of a surface language. This paper describes our surface language, the two approaches, and the two implementations that follow these approaches. Keywords: Grammarware; modelware; surface language.

We present an overview of rewriting-based systems that were presented at the workshop.

In this paper we propose a technique to automate the process of building translators between operations languages, a family of DSLs used to program satellite operations procedures. We exploit the similarities between those languages to semi-automatically build a transformation schema between them, through the use of annotated grammars. To improve the overall translation process even more, reducing its complexity, we also propose an intermediate representation common to all operations languages. We validate our approach by semi-automatically deriving translators between some operations languages, using a prototype tool which we implemented for that purpose.
