Service-oriented architecture (SOA) has emerged as a promising paradigm for the inter-organizational sharing of domain-specific capabilities. Perhaps an equally important emergence is the use of SOA to manage the sharing of disparate information within a distributed environment. SOA provides a platform for organizations to enable the user-driven advertisement, discovery, and retrieval of data. A major...
It is accepted that domain based development is playing an important role on IT projects today. Following such idea, this paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. Our discussion presents a way of sharing business domain models, developed in different project sites,...
Some of the characteristics that make service-oriented architectures appealing for enterprise applications also make them vulnerable to security breaches. The vulnerabilities are primarily due to the openness of the service-execution environment, to the dynamic run-time selection and composition of services, and to the autonomy of the individual services. In this paper, we describe these vulnerabilities...
This paper addresses a methodology for developing the various user interfaces (UI) of a workflow information system (WIS), which are advocated to automate business processes, following a model-centric approach based on the requirements and processes of the organization. The methodology applies to: 1) integrate human and machines based activities, in particular those involving interaction with IT applications...
In this experience report we present Business Process Illustration, a technique supporting experience-grounded validation of new business processes by subject matter experts.
One of the challenges in SOA is to provide an efficient and effective way to select compatible Web service(s) and compose them into a functional service process that satisfies a user's needs. Moreover, the Web services(s) selected may be integrated with structures such as branches and merges to fulfill a task. This paper describes our system architecture and strategies on Web services composition...
The distribution of services spanning across organizational boundaries raises problems related to intellectual value that are less explored in current service oriented research. Being a way to manage the intellectual rights between service consumers and service providers, licenses are critical to be considered in services. A service license describes the terms and conditions for the use and access...
Service-Oriented Architecture (SOA) is an effective paradigm for publishing common features as services and reusing the published services in building applications. Therefore, reusability of services is a key criterion for evaluating the quality of services. The evaluation target for reusability in our model is the service, applied to both atomic and composite service. Reusability models for conventional...
Semantic Web service composition is about finding services from a repository that are able to accomplish a specified task. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine. The composer...
The paper describes ways to support outsourcing arrangements using collaborative technologies. It identifies outsourcing falling into the general class of socio-technical systems. It then suggests any supporting systems must emphasize both the social arrangements as well as any functionality needed to carry out the outsourcing goal. At the same time they should provide the dynamic capability to change...
Identifying proper business processes, formalizing and documenting them has always been a challenge. Maintaining them in synchronization with changing business needs makes the problem harder. It becomes even harder when business processes are fully or partially implemented in IT systems where changes to the business cause changes in IT configurations. This paper presents an approach how IT configurations...
Today, most approaches for inter-organizational business processes start bottom-up from the interfaces and the workflows of each partner described on the IT layer. Alternatively, one may start from the commitments and agreements between business partners to reach their complementary business goals. The latter approach is target of the UN/CEFACT Modeling Methodology (UMM), which models a global choreography...
Various approaches to automate the observance of compliance requirements have recently been proposed. Since there is no all-round solution available within the foreseeable future, we propose a classification scheme for existing approaches that address different aspects of automating compliance. A layer model is used for linking laws and regulations with a company's IT system. The "policy layer"...
To keep an overview on complex e-commerce collaborations several models are used to describe them. When models overlap in describing a collaboration, the overlapping information should not contradict. Models are of different nature and maintained by different people. Therefore, keeping model-overlap contradiction-free is challenging. In this paper we propose a novel approach for maintaining models...
In this paper, we report our experience in the implementation of a module for creating user profiles of Web visitors by using Zones, Weights and Actions. The module is part of Gugubarra 2.0, a tool for better understanding and management of communities of registered Web visitors, currently being developed by the database group at the Computer Science Institute of the Goethe University in Frankfurt...
Managing business collaboration is about coordinating the flow of information among organizations and linking their business processes into a cohesive whole. A consistent outcome is expected within and among involving organization. However, inadequate coordination onthe autonomous, heterogeneous, and long-lasting cross-organizational business processes can lead to inconsistent execution in loosely-coupled...
