This paper introduces an implementation of the Context-Driven Meta-Modeling Paradigm (CDMM-P). This implementation is the proof of concept for the CDMM-P as it shows that the idea of the CDMM-P is feasible. The software system presented here takes the form of the Context-Driven Meta-Modeling Framework (CDMM-F). This framework plays the key role in the Context-Driven Meta-Modeling Technology (CDMM-T) dedicated to generating software system artifacts in a model-driven manner. In contrast to all contemporary approaches to meta-modeling, the meta-model is dynamically loaded from the application context file. In result, the framework has a self-organizing structure and the modeling language does not have a fixed hardcoded predefined structure. This structure, as well as the set of meta-model elements, plays the role of the parameter for the general modeling tool, a part of which is presented in this paper.

The novel and crucial point of this paper is the illustration of the application of close ontology based meta-modeling to defining the open ontology based construction of modeling languages (meta-models). This approach is a generalization of Object Management Group (OMG) standards related to Model Driven Architecture (MDA). The existing modeling tools supporting the traditional approach can be reused when open ontology based meta-modeling tools are implemented. This paper describes Context-Driven Meta-Modeling Meta-Modeler (CDMM-Meta-Modeler) ‒ the Eclipse Plugin that constitutes such an open ontology based meta-modeling tool. The tool constitutes an implementation of the diagramming aspect for the Context-Driven Meta-Modeling Framework (CDMM-F), which is one of several possible implementations of the Context-Driven Meta-Modeling Paradigm (CDMM-P).

The paper introduces a novel Context-Driven Meta-Modeling Paradigm (CDMM-P) and discusses its properties. The CDMM-P changes the traditional division of responsibilities within the data layer in software systems. It facilitates the interchangeable usage of both objects representing data and objects representing relationships. The decomposition of specific responsibilities results in the weakening of internal data model dependencies. This in turn allows for run-time construction of the whole data model. The proposed paradigm facilitates exceptional flexibility in the implementation of the data layer in software systems. It may be applied to domain modeling in enterprise applications as well as to the modeling of any ontology, including the construction of modeling and meta-modeling languages. As such, CDMM-P underpins a broad domain of Context-Driven Meta-Modeling Technology (CDMM-T).

The paper is focused on the bug fixing handling business process rather then just on fixing a bug. The tool presented here is dedicated to supporting the business process of bug fixing and not to bug fixing itself. It is addressed especially to small teams having a common testing team.

A new approach to project effort estimation is presented in this paper. It is related to Delphi method of estimation by experts. It also makes use of the business processes and business rules related to the newest OMG standards. A software tool implemented to verify the concept correctness is described.
