Domain Specific Languages (DSLs) play a cornerstone role in Model-Driven Software Development for representing models and metamodels. DSLs are usually defined in terms of their abstract and concrete syntax only. this allows the rapid and inexpensive development of DSLs and their associated tools (e.g., editors), but does not allow the representation of their behavioral semantics, something especially important for model operations like simulation and verification. In this paper we explore the use of Maude as a formal notation for describing models and metamodels, including the specification of their dynamic behavior.

In order to make business service more flexible and reusable, it is desirable to provide users or applications the same service but with different service quality, different interaction paths, or with different outcomes. We call this design principle as Service Differentiation. this paper describes a fully functional mechanism where variability is externalized as usage context and context aware policies so that the core business process(es) need not to be altered for any anticipated changes. Service differentiation is realized by configured business processes and interfaces, and the dynamic 'binding' between user/application with a specific interface is determined by usage context during service invocation time.

this paper describes the requirements and high-level design of a service-oriented architecture for demand- driven e-government. Central to this architecture is the integration of services from different government agencies and private parties to create truly demand- driven e-services to citizens. Starting from a description of the requirements, we give a functional architecture and identify technologies that may be used to realize this functionality. this architecture is the first to combine service orientation, identity management, business process management, and semantic Web technologies to implement this vision of integrated, demand-driven services.

Mobile devices are today capable to run and maintain long running interaction and communication between people and external systems over cell and local proximity networks. In this paper, we will describe a mobile workflow system which provides a platform for deploying and managing process oriented applications and services in mobile devices. We will discuss the architecture and the implementation aspects of our prototype. We will discuss the value of this system to the users in managing and partly automating their regular activities in both personal and professional life. In addition, we will argue the use of standards and the advantages of integrating two open standards on web forms and web services in order to execute the mobile workflows.

the discipline of enterprise architecture advocates the use of models to support decision-making on enterprise-wide information system issues. In order to provide such support, enterprise architecture models should be amenable to analyses of various properties, as e.g. the availability, performance, interoperability, modifiability, and information security of the modeled enterprise information systems. this paper presents a software tool for such analyses. the tool guides the user in the generation of enterprise architecture models and subjects these models to analyses resulting in quantitative measures of the chosen quality attribute. the paper describes and exemplifies boththe architecture and the usage of the tool.

Using complex event rules for capturing dependencies between business processes is an emerging trend in enterprise information systems. In previous work we have identified a set of requirements for event extensions for business process modeling languages. this paper introduces a graphical language for modeling composite events in business processes, namely BEMN, that fulfills all these requirements. these include event conjunction, disjunction and inhibition as well as cardinality of events whose graphical expression can be factored into flow-oriented process modeling and event rule modeling. Formal semantics for the language are provided.

In this paper we model and analyze a business case from a dual view of process and service perspectives. We discover that a common understanding on transactional reliability is missing between the parties collaborating in this case. therefore, we propose to enclose a transactional quality of service (TxQoS) specification in a service level agreement (SLA) to infuse transactional semantics into e- contracts for contract-driven service-oriented processes. A contract structure and a TxQoS framework are developed toward the unambiguous interpretation and understanding of transactional qualities between the business and technical communities as well as between the contracting parties. thus, reliability is guaranteed both technically, via transaction management, and legally via contracts.

Software cities alias application landscapes of large enterprises comprise tens or even hundreds of IT applications. Structuring software cities into domains is an important task of enterprise architects. the quality of the resulting domain model is crucial for the success of enterprise architecture management and an important tool for the governance of the development of an enterprise's application landscape. this paper presents a novel method for constructing domain models based on business services, business objects, and business dimensions. the method has been validated in numerous industrial projects.

Compliance management (CM) is the management process that an organization implements to ensure organizational compliance with relevant requirements and expectations. It is a continual, manual and labor intensive process that is proved to be of great challenge for many organizations. CM affects almost every aspect of an organization and is in nature a complex problem due to voluminous knowledge and data involved. In our attempts to automate and simplify compliance, we propose and examine a semantic rule-based approach for modeling compliance knowledge withthe use of semantic Web rules (SWRL) and Web ontology language (OWL). We study the use of exception handling approach to create a more robust rule base to deal with data incompleteness in the semantic Web.

Enterprise application integration (EAI) is a major challenge for enterprises to ensure optimal utilization of their landscape of diverse applications . Enterprise application integration patterns help to ease this problem by describing recurring EAI problems and proposing possible solutions. As of today , message-oriented middleware (MOM) is state- of-the-art for EAI integration middleware infrastructures. However , space-based computing (SBC) has been found to offer essentially the same qualities as MOM in terms of asynchronous, reliable and loosely coupled communication and might therefore provide a suitable alternative to MOM in the field of EAI. the objective of this paper is to provide a comparison of MOM and SBC from an application's point of view through an in-depth analysis of EAI patterns, assuming SBC instead of MOM as their underlying middleware .
