Usability evaluation of the domain specific language for spatial simulation scenarios

This article presents the results of a usability evaluation initiative conducted on the Domain Specific Language for Spatial Simulation Scenarios (short name DSL3S) and its supporting tools. This language applies a Model-Driven Development approach to spatial simulation, providing model development through the composition of graphical elements and the subsequent transformation to source code. Potential users trained in disciplines related to Geographic Information Systems were exposed for a first time to the language with an introductory exercise. After installing the supporting tools and developing a simple spatial simulation model, participants then evaluated the language and its tools by answering a questionnaire. The results of this evaluation point to a good degree of usability, with particularly positive appreciations of the DSL3S supporting tools. Notwithstanding, participants also show some reluctance in adopting such a development framework, hinting at some reminiscent scepticism towards domain specific modelling languages and Model-Driven Development.
