Towards Definition of a Unified Domain Meta-model

The domain model is one the most important artifacts produced at early stages of software development which can be reused efficiently during software design and implementation. Unfortunately, there is no clear explanation what should be included in the domain model to minimize modeling effort and maximize the potential later benefits. Authors of the paper try to address this gap by proposing a definition of a unified domain meta-model, which is the result of literature overview and authors' own experiences. The purpose of the literature analysis was to assess the existing definitions of domain models and to identify their common parts. On that basis, a unified meta-model was proposed. Its application in real projects confirmed the meta-model usefulness.
