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)
One of crucial problems for model transformation implementations is an efficient implementation of pattern matching. The paper addresses this problem for MOLA tool implementing the model transformation language MOLA. Another goal has been to keep the implementation as simple as possible. The paper presents one possible solution to the combined problem where(More)
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 a(More)
The paper describes the MOLA Tool, which supports the model transformation language MOLA. MOLA Tool consists of two parts: MOLA definition environment and MOLA execution environment. MOLA definition environment is based on the GMF (Generic Modeling Framework) and contains graphical editors for metamodels and MOLA diagrams, as well as the MOLA compiler. The(More)
