Intended Use

Model-driven architecture frameworks provide an approach for specifying systems independently of a particular platform and for transforming such system models for a particular platform, but development processes based on MDA are not widely used today because they are in general heavy-weight processes: in most situations they cannot deliver (incrementally) partial implementations to be executed immediately. Executable UML means an execution semantics for a subset of actions sufficient for computational completeness. This chapter uses Alf as the fUML-based action language to describe the operations for iComponent: the proposed solution for a platform-independent component model for dynamic execution environments. Moreover, a UML profile for modeling components is defined and applied, following agile principles, to the development of service-oriented components for dynamic execution environments. The intended use of the proposed approach is enterprise systems.

Process Participant

Collaboration management involves capturing the collaboration process, coordinating the activities of the participating applications and humans, and/or providing awareness, i.e. information that is highly relevant to a specific role and situation of a process participant. In this paper, we propose an awareness provisioning solution that allows focusing, customizing, and temporally constraining the awareness delivered to each process participant. Unlike existing collaboration management technologies (such as workflow and groupware) that provide only a few built-in awareness choices, the proposed awareness solution allows the specification of what information is to be given to what users and at what time. To support this advanced level of awareness, we require the definition of awareness roles and the specification of corresponding awareness descriptions. Awareness roles can be dynamically created and associated with any process scope. Awareness descriptions define what information is to be given to users in an awareness role. Since awareness roles are created or become visible when they are needed, the existence of an awareness role also determines the appropriate time interval during which the information specified in the awareness description can be delivered. This awareness provisioning approach minimizes information overloading and allows the combination of process-relevant information with external information as needed by the process participants. The proposed awareness provisioning solution is employed by the Collaboration Management Infrastructure (CMI), a federated system for collaboration process management. In this paper, we introduce an Awareness Model (AM) for creating awareness specifications and defining related execution semantics. Awareness specifications in AM are specialized composite event specifications that define patterns of process-related events and external events, as well as how information should be digested from them. We also describe the implementation of CMI's awareness provisioning engine and related tools.
