Introducing the Common Non-Functional Ontology
- 2007
-
In: Enterprise Interoperability II. - London : Springer. - 9781846288579 - 9781846288586 - 9781447171317 ; , s. 633-645

Conference paper (peer-reviewed)abstract
- Enterprise systems interoperability is impeded by the lack of a cohesive, integrated perspective on non-functional aspects (NFA). We propose to respond to the fragmentation in NFA research by supporting a shared, common understanding. For this purpose:- first, we propose a common NFA ontology, which generalizes and integrates the different non-functional aspects under a common top-level ontology. Second, we introduce a series of specialized ontologies on specific non-functional aspects, such as trust, risk, privacy, threat and misuse. By fostering a consensual and shared view of the non-functional aspects domain, we aim to move closer to enhancing semantic enterprise interoperability. This shared perspective on what non-functional aspects are and how they relate to the other 'functional' aspects of enterprise systems, is the key towards enterprise interoperability.

Requirements for a business process model repository : A stakeholders’ perspective.
- 2010

Conference paper (peer-reviewed)abstract
- Reuse of business process models is the act of designing business processes by using existing process models. Reuse of business process models has been considered as a way to reduce the cost of modeling business processes from scratch. In order to support reuse a critical mass of process models is required which justifies the effort of maintaining a process model repository. However, recent studies show that complete repositories which can support reuse are not yet available. One of the reasons is that stakeholder requirements for process model repositories have not been sufficiently investigated. Therefore, the purpose of this work is to define requirements of a process model repository from stakeholders’ (researchers and practitioners) perspective. In this study, we start by eliciting preliminary requirements (defined as propositions) through an exploratory study followed by an empirical validation of the propositions. Based on the analysis of the results we define as a set of requirements for a process model repository.

Towards Cross Language Process Model Reus : A Language Independent Representation of Process Models
- 2009

In: Practice Of Enterprise Modeling, Proceedings. - Berlin, Heidelberg : Springer Berlin/Heidelberg. - 9783642053511 - 9783642053528 ; , s. 176-190

Conference paper (peer-reviewed)abstract
- Process model reuse is becoming a key approach to addressing the challenges of modeling business processes from scratch. A repository is, therefore, essential to store and manage process models for future reuse. In this paper, we develop a logical data model that enables a Universal Process Repository to store process models in the form of process elements, independent of any process modelling language. In order to store process models in the process repository we propose an algorithm that automatically extracts data from the repository and converts them to process models on the fly. Finally, we use a case study to present data stored about a process model in the repository and to illustrate the development of process models from the data stored in the repository.

A business process metadata model for a process model repository
- 2010
-
In: Enterprise, Business-Process and Information Systems Modeling. - Berlin : Springer Berlin/Heidelberg. - 9783642130519 - 9783642130502 ; , s. 287-300
-
Conference paper (peer-reviewed)abstract
- Today reuse of business process models is becoming increasingly important. One of the proven solutions for reusing business process models is the use of repositories. Repositories should have process models and process metadata that can help users in searching, understanding, and interpreting process models. The purpose of this paper is to propose a Business Process Metadata Model (BPMM) that would facilitate a) locating process models, b) understanding and/or interpreting process models, and c) navigating a process model repository. In order to evaluate the BPMM, an empirical study is conducted to measure consistency and correctness of annotating business processes by using BPMM.

Closing the user-centric service coordination cycle by means of coordination services
- 2011
-
In: CAiSE Forum 2010 on Information Systems Evolution. - Berlin, Heidelberg : Springer Berlin Heidelberg. - 3642177212 - 9783642177217 ; , s. 267-282
-
Conference paper (peer-reviewed)abstract
- In the future vision of an Internet of Services, users take an active role in service selection and composition. In this context, web services are mostly interfaces to real services and can be classified as coordination services with respect to the latter. To enable users to perform service composition, the effect of the coordination services must be described in such a way that users are not only able to discover services but also to detect and prevent possible conflicts in their composition. To meet these requirements, a service description language for coordination services is proposed based on the REA business ontology.

Purpose driven value model design
- 2009
-
In: CEUR Workshop Proceedings.
-
Conference paper (peer-reviewed)abstract
- It is increasingly recognized that value models offer an abstraction that is useful for the exploration of new business networks and their properties. Among others, value models can be used as input for a risk analysis that is crucial in cross-organizational business process design. However, as value models can be used for many different purposes, there is a risk that they become overloaded and difficult to understand. In this paper we claim that the form and contents of a value model should be governed by its purpose. We identify a number of basic purposes of value models and outline how a value model is affected by those. The approach builds on an analysis and classification of resources and resource exchanges.

Conceptual models and levels of modeling
- 2006
-
In: 5th International Conference on Business Informatics Research, BIR 2006. - : International Conference on Business Informatics Research. ; , s. 9-16
-
Conference paper (peer-reviewed)abstract
- Conceptual modeling is a powerful tool for describing, defining and understanding some world under consideration. To properly understand conceptual modeling one can turn conceptual modeling on itself and develop meta models. In this paper we inquiry into the relation between conceptual models and meta models. We identify and discuss some issues in modeling and in meta modeling that have puzzled our minds in recent work with ontologies.

Describing coordination services with REA
- 2010
-
In: CAiSE 2010 Workshop BUSITAL’10. ; , s. 120-134
-
Conference paper (peer-reviewed)abstract
- Coordination services are services, possibly implemented as web services, that support the coordination of (real-world) services that a consumer would like to take. To support users of a future Internet of Services, the effect of the coordination services must be described in such a way that users are not only able to discover services but also to detect and prevent possible conflicts in their composition. In this paper, REA is applied as a solution approach to this requirement. The REA business ontology has proven to be a good foundation for the description of services, but we argue that its conceptualization of commitments can be improved.

A declarative foundation of process models
- 2005
-
In: ADVANCED INFORMATION SYSTEMS ENGINEERING, PROCEEDINGS. - Cham : Springer International Publishing. - 3540260951 ; , s. 233-247
-
Conference paper (peer-reviewed)abstract
- In this paper, a declarative foundation for process models is proposed. Three issues in process management and modeling are identified: business orientation, traceability, and flexibility. It is shown how these issues can be addressed by basing process models on business models, where a business model focuses on the transfer of value between agents. As a bridge between business models and process models, the notion of activity dependency model is introduced, which identifies, classifies, and relates activities needed for executing and coordinating value transfers.
