BPMN4CP Revised - Extending BPMN for Multi-Perspective modeling of Clinical Pathways 49

Clinical Pathways (CPs) can be seen as business processes of hospitals or clinical institutions. modeling these pathways is an emerging field of research, as it provides promising benefits for systems integration, quality management and documentation. The Business Process model and Notation (BPMN) provides a range of process-related concepts but naturally lacks in representing specific aspects from the CP domain. Therefore, the BPMN extension BPMN4CP was designed in a previous research project. In accordance with research guidelines from Design Science, the extension ran through an iteration based on its practical application within a telemedical project. Based on several new requirements, the extension was revised regarding to the integration of resources, documents, objectives and quality indicators. These concepts were assigned to particular perspectives and diagrams in order to support model complexity management and provide appropriate diagrams for respective stakeholders. In order to provide a commonly usable extension, these enhancements were implemented as BPMN meta model extension.

Conceptual modeling languages are valuable means for analyzing, designing and controlling information systems. In recent years, some languages became de facto standards in their particular field of application, which simultaneously leads to an increasing demand for domain-specific extensions in order to both benefit from dissemination and apposite concepts. However, recent studies reveal a remarkable lack of methodical support for language extensibility, which hampers systematic extension design, comprehensibility and interoperability. This research article therefore aims to outline different meta model extension mechanisms based on an analogy to extension principles from the field of Software Engineering. The techniques of hooking, aspects, plug-ins and add-ons are presented and their adaptation is elaborated by the definition of additional extension packages within the meta Object Facility (MOF) in order to provide constructs for the definition of extensible meta models.

The Business Process model and Notation (BPMN) is the prevalent conceptual modeling language for business process modeling and process analysis. BPMN benefits from its expressiveness and the well-defined meta model, which is defined by the meta Object Facility (MOF). The emergence of BPMN entails an increasing demand for language extensions in order to both benefit from the dissemination and apposite concepts. Although BPMN is one of very few languages that explicitly provides capabilities for its extension, the proposed mechanism reveals some shortcomings and inaccuracies concerning model abstractions, specificity and semantical clarity. A list of improvable aspects is hence provided based on an in-depth analysis of the extension mechanism. The analysis has a special focus on the abstract syntax (BPMN meta model). Several techniques for enhanced BPMN extension design are proclaimed by adapting alternative mechanisms for language extensibility: Profiling, under specification (hooking) and annotation (plugins and add-ons). The stated mechanisms are partly adapted from other modeling languages (profiling) or the field of Software Engineering (hooking, plug-ins, add-ons). Each approach is described by its core concepts, its application and by some examples. The approaches are finally compared regarding several criteria.

During the last years, various MOF-based modeling languages became de-facto standards in their field of application. Due to their common application and dissemination the need for extending these languages also increased in order to integrate domain-specific concepts or facilitate interoperability and tool support. However, only the minority of MOF-based modeling languages provides an extension mechanism and even those defining one, reveal some syntactical issues (e.g., BPMN). Also MOF itself does not provide an integrated and consistent extension mechanism. We therefore proclaim the application of the UML-based profile mechanism for extending the abstract syntax of MOF-based languages while keeping their original meta models unaffected. Further, the application of the Diagram Definition (DD) standard for extending the concrete syntax is outlined and both aspects are integrated. The research article proposes a generic extension method for MOF-based languages based on existing concepts and constructs from the MOF environment. In this context, the article also discusses the positions of the Profiles package and the Diagram Graphics (DG) package within the OMG meta hierarchy.

BPMN is one of the most prevalent modeling languages within the field of enterprise modeling and constitutes as de facto standard for business process modeling. BPMN provides explicit capabilities for extending the vocabulary of the language. While a range of BPMN extensions evolved during the last years, only very few of them conduct the extension mechanism. Instead, the vast majority of extensions is designed in an ad-hoc manner and lacks in conformity to the BPMN standard, what hampers interoperability, extension integration and model reuse. We suppose, that some architectural shortcomings and barriers of the extension mechanism itself provoke missing application. For instance, BPMN reveals abstraction conflicts and inaccuracies within the extension design. The extension mechanism also lacks in regard of exactly specifying those elements that are extended. Further, the exchange of both the concrete syntax and serialized extended model data remains vague. We therefore present an adaptation of the well-established profile mechanism from the UML Infrastructure in order to facilitate a straightforward definition of the abstract syntax for BPMN extensions. Additionally, the definition of the concrete syntax is supported by an instantiation of OMG's Diagram Definition (DD) specification in order to provide an integrated extension definition and exchange specification. The migration of existing, standard-conform BPMN extensions is outlined by a transformation process.

During the last years, several enterprise modeling languages became de-facto standards in their particular field of application. This dissemination increased the need for extending these languages in order to both specify concepts domain-specifically and integrate additional concepts. However, only the minority of enterprise modeling languages provides an extension mechanism and even those defining one, reveal some syntactical shortcomings. This issue can be also observed in the context of the well-known meta modeling language MOF and its correspondingly defined enterprise modeling languages like BPMN. This position paper therefore elaborates an adaptation of the profile mechanism from UML for generic extensions of meta models in the field of enterprise modeling. Therefore, the characteristics of profiling are abstracted to the meta meta model layer and comprehensively integrated within an framework for the integrated definition of meta models. The Stereotype concept is thereby applied to several parts of meta models including also aspects of the concrete syntax as well as semantics. The proposed framework serves as reference architecture for the derivation of meta modeling language specific implementations (e.g., within MOF).
