ABSTRACT
We present the proactive behavioural features of PROMENADE, a process modelling language for formalizing the construction of software process models. PROMENADE aims at improving expressiveness, standardization, flexibility and reuse in software process modelling. In this article we focus on expressiveness, which is achieved by means of a declarative (instead of imperative) proactive control-flow based on precedence relationships. Different families of such precedences have been defined within the language (namely, basic, derived and dynamic). Also, PROMENADE provides (1) a comprehensive parameter task-binding mechanism to keep track of document-flow between tasks; (2) a high level notation to define new precedence relationships, which may be used to tailor the language to the specific needs of each user and process; (3) the definition of flexible models by leaving some parts undefined until enactment time. The specific concepts necessary to model a software process are defined and integrated into the UML metamodel. The extended metamodel is converted into a UML profile using stereotypes, constraints and tag definitions.

Recommendations
A Meta-Model Based Approach to UML Modelling
UKSIM '08: Proceedings of the Tenth International Conference on Computer Modeling and SimulationThis paper is devoted to a meta-model based approach to UML systems modelling. The approach allows creating a system model by operating with artefacts from the problem domain, followed by generation of a UML model. The discussed approach is illustrated ...
Domain-specific language modelling with UML profiles by decoupling abstract and concrete syntaxes
UML profiling presents some acknowledged deficiencies, among which the lack of expressiveness of the profiled notations, together with the high coupling between abstract and concrete syntaxes outstand. These deficiencies may cause distress among UML-...
Transformation techniques in the model-driven development process of UWE
ICWE '06: Workshop proceedings of the sixth international conference on Web engineeringDevelopment of Web software is still an inefficient and error-prone process. We need integrated techniques and tool support for automated generation of Web systems. The goal of model-driven development (MDD) is to tackle these problems introducing a ...
