We are concerned with a core aspect of the processes of obtaining conceptual models. We view such processes as information gathering dialogues, in which strategies may be followed (possibly, imposed) in order to achieve certain modelling goals. Many goals and strategies for modelling can be distinguished, but the current discussion concerns meta-model driven strategies, aiming to fulfil modelling goals or obligations that are the direct result of meta-model choices (i.e. the chosen modelling language). We provide a rule-based conceptual framework for capturing strategies for modelling, and give examples based on a simplified version of the Object Role Modelling (ORM) meta-model. We discuss strategy rules directly related to the meta-model, and additional procedural rules. We indicate how the strategies may be used to dynamically set a modelling agenda. Finally, we describe a generic conceptual structure for a strategy catalog.
