— The paper proposes a more formalized definition of UML 2.0 Activity Diagram semantics. A subset of activity diagram constructs relevant for business process modeling is considered. The semantics definition is based on the original token flow methodology, but a more constructive approach is used. The Activity Diagram Virtual machine is defined by means of(More)
In this paper we introduce a novel wide-profile graphical tool-building platform GrTP which is based on the principle of separating semantic domain model processing and user interface components. This principle is enabled in GrTP by a meta-model for visual information presentation (" interface meta-model "). A novel feature of GrTP is that it consistently(More)
Currently many different modeling languages are used for workflow definitions in BPM systems. Authors of this paper analyze the two most popular graphical languages, with highest possibility of wide practical usage-UML Activity diagrams (AD) and Business Process Modeling Notation (BPMN). The necessary in practice workflow aspects are briefly discussed, and(More)
In this paper a sequence of model transformation languages L0, L1, L2 is defined. The first language L0 is very simple, and for this language it is easy to build an efficient compiler to C++. The next language L1 is an extension of L0, and it contains powerful pattern definition facilities. The last language L2 is of sufficiently high level and can be used(More)
