This book provides the most complete formal specification of the semantics of the Business Process Model and Notation 2.0 standard (BPMN) available to date, in a style that is easily understandable for a wide range of readers – not only for experts in formal methods, but e.g. also for developers of modeling tools, software architects, or graduate students specializing in business process management.BPMN – issued by the Object Management Group – is a widely used standard for business process modeling. However, major drawbacks of BPMN include its limited support for organizational modeling, its only implicit expression of modalities, and its lack of integrated user interaction and data modeling. Further, in many cases the syntactical and, in particular, semantic definitions of BPMN are inaccurate, incomplete or inconsistent. The book addresses concrete issues concerning the execution semantics of business processes and provides a formal definition of BPMN process diagrams, which can serve as a sound basis for further extensions, i.e., in the form of horizontal refinements of the core language.To this end, the Abstract State Machine (ASMs) method is used to formalize the semantics of BPMN. ASMs have demonstrated their value in various domains, e.g. specifying the semantics of programming or modeling languages, verifying the specification of the Java Virtual Machine, or formalizing the ITIL change management process.This kind of improvement promotes more consistency in the interpretation of comprehensive models, as well as real exchangeability of models between different tools. In the outlook at the end of the book, the authors conclude with proposing extensions that address actor modeling (including an intuitive way to denote permissions and obligations), integration of user-centric views, a refined communication concept, and data integration.

This book presents a proposal for designing business process management (BPM) systems that comprise much more than just process modelling.Based on a purified Business Process Model and Notation (BPMN) variant, the authors present proposals for several important issues in BPM that have not been adequately considered in the BPMN 2.0 standard. It focusses on modality as well as actor and user interaction modelling and offers an enhanced communication concept. In order to render models executable, the semantics of the modelling language needs to be described rigorously enough to prevent deviating interpretations by different tools. For this reason, the semantics of the necessary concepts introduced in this book are defined using the Abstract State Machine (ASM) method. Finally, the authors show how the different parts of the model fit together using a simple example process, and introduce the enhanced Process Platform (eP2) architecture, which binds all the different components together. The resulting method is named Hagenberg Business Process Modelling (H-BPM) after the Austrian village where it was designed. The motivation for the development of the H-BPM method stems from several industrial projects in which business analysts and software developers struggled with redundancies and inconsistencies in system documentation due to missing integration.The book is aimed at researchers in business process management and industry 4.0 as well as advanced professionals in these areas.

FoIKSis intendedto beabiannualeventfocussingontheoreticalfoundations ofinformationandknowledgesystems.Itaims to takeupthe oldtraditionofthe conferenceseries \MathematicalFundamentals ofDatabaseSystems" (MFDBS) which encouraged East-West collaboration in the e ld of database theory. F- mer MFDBS conferences were held in Dresden in 1987 (Springer LNCS 305, edited by Joachim Biskup, J anos Demetrovics, Jan Paredaens, and Bernhard Thalheim), in Visegr ad in 1989 (Springer LNCS 364, edited by J anos Demet- vics and Bernhard Thalheim), and in Rostock in 1991 (Springer LNCS 495, edited by Bernhard Thalheim, Jan os Demetrovics, and Hans-Detlef Gerhard). Another goal of the MFDBS conference series has always been to attract researchers working in mathematical e lds such as discrete mathematics, c- binatorics, logics, and nite model theory who are interested in applying their theories to researchon databaseand knowledgebase theory.To that end, FoIKS takes up the tradition of providing a forum for mathematical foundations in a speci c branch of computer science. A r st attempt to reestablish the MFDBS tradition was made in 1995 with a follow-up workshop \Semantics in Datab- es" to ICDT (Springer LNCS 1358, edited by Bernhard Thalheim and Leonid Libkin).

Conceptual modeling is fundamental to the development of complex systems, because it provides the key communication means between systems developers, end-usersandcustomers.Conceptualmodelingprovideslanguages,methods and tools to understandandrepresentthe applicationdomain;to elicitate,concep- alizeandformalizesystemrequirementsanduserneeds;tocommunicatesystems designs to all stakeholders; to formally verify and validate system designs on high levels of abstractions; and to minimize ambiguities in system development. Initially, conceptual modeling mainly addressed data-intensive information s- tems and contributed to data modeling and database application engineering. The area of conceptual modeling has now matured to encompass all kinds of application areas such as e-applications (including e-business and e-learning), web-based systems (including the semantic web and ubiquitous systems), life science and geographic applications. The annual International Conference on Conceptual Modeling serves as the premiere forum for presenting and discussing researchand applications in all - eas associatedwith conceptual modeling. This year,the Call for Papers solicited contributions dealing with logical and philosophical foundations of conceptual modeling, information modeling concepts including ontologies, correctness in modeling, web-based and mobile information systems, semi-structured data and XML, information and database integration, information retrieval, organization andevaluation,designmethodologiesandtools,reuse,re-engineeringandreverse engineering, quality assurance in conceptual modeling, conceptual change and evolution, data warehousing and data mining, spatial and temporal modeling, business process and work?ow modeling, knowledge management, requirementselicitation, and advanced applications.

The LNCS journal Transactions on Large-Scale Data- and Knowledge-Centered Systems focuses on data management, knowledge discovery, and knowledge processing, which are core and hot topics in computer science. Since the 1990s, the Internet has become the main driving force behind application development in all domains. An increase in the demand for resource sharing across different sites connected through networks has led to an evolution of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications providing high scalability. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between grids, P2P systems, and agent technologies is the key to data- and knowledge-centered systems in large-scale environments. This, the sixth issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, contains eight extended and revised versions of papers selected from those presented at DEXA 2011. Topics covered include skyline queries, probabilistic logics and reasoning, theory of conceptual modeling, prediction in networks of moving objects, validation of XML integrity constraints, management of loosely structured multi-dimensional data, data discovery in the presence of annotations, and quality ranking for Web articles.
