“…In [19] a work very similar to the one reported here is described: the meta-model is expressed in UML, with added constraints in OCL, and the resulting meta-model is -quite comprehensibly-similar. However, there are also relevant differences.…”

“…Our meta-model was specifically structured to be used in an EMF/GMF framework: this is reflected in the meta-model itself, e.g., composition relations and decorators are often used instead of inheritance relations. There are also some semantic differences between the two meta-models: the meta-model in [19] does not account for sub-problems and descriptions involving multiple frames. Finally, we have implemented the PF editor: a full working prototype of a PF modeling tool, able to generate UML compatible models.…”

Problem frames are an approach to requirements modeling that is gaining increasing attention and popularity. The approach provides useful concepts and methodological guidelines. However, problem frames are not equipped with an expressive and complete notation and they lack tools support. These limitations can be addressed by introducing a suitable meta-model to formally define the notation. In this way it is also possible to identify the aspects that are not covered by the problem frames notation and to provide hooks for user-defined extensions. The meta-model is also expected to support the underlying analysis methodology. Furthermore, it can provide the basis for building a tool supporting both the editing of problem frames and the other activities associated with the approach (frame concern, composition, etc.). This paper presents a meta-model that addresses the former issues and was used for building a tool with the EMF/GMF technology.

“…In order to express constraints, we use OCL [9], as already done in previous work (see for instance [10] and [11]). In particular, the constraint mentioned above is specified by the following OCL statement: In order to show that the meta-model is actually suitable for representing aggregated domains, we apply it to model the Gate&Motor domain in the Sluice gate control problem (see Fig.…”

“…In particular, PFs allow analysts to analyze complex problems by decomposing them into simpler ones; these basic problems are modeled according to basic patterns (i.e., the frames, which represent common, well understood problems); then it is necessary to (informally) show that the user requirements are satisfied by the outcome of the previously defined modeling activity; finally, the various problem frames are composed into a complete description. Meta-models for Problem Frames have been proposed by a few researchers [2], [3], [5], [6], [7], [10], including the authors of this paper [11]. However, all these meta-models (except, in a partial way [12]) do not address the (de)composition of problems, which is a fundamental aspect of the PF technique.…”

Problem frames are an approach to requirements modeling that is gaining increasing attention and popularity. A few meta-models have already been proposed to precisely define the notation and -in some cases-to support the construction of tools. However, the meta-models proposed till now concentrate on modeling the single problem frame, without addressing the whole problem. This is particularly limiting, since one of the strengths of the problem frames approach is in tackling the complexity of problems by guiding their decomposition into sub-problems, and in identifying recurring patterns of elementary problems. In order to support this fundamental activity, a meta-model has to support the notion of sub-problems and sub-domains; moreover it must provide suitable means to represent problems in intermediate situations during the (de)composition phases. This paper presents a meta-model that solves the aforementioned problems and provides a suitable base for the construction of a tool based on the EMF/GEF technology.
