Capturing concerns that crosscut the boundaries of multiple components in software architecture descriptions is problematic. Standard description languages, such as UML, do not provide adequate means to understand and modularize such concerns, but aspect-oriented programming techniques do. This paper explores and analyzes the suitability of UML for aspect-oriented architectural modeling. It tak...

Aspect-orientation provides support for “ Separation of Concerns” by means of techniques that first isolate and then weave concerns. Most work in aspect-orientation has achieved such goals at the programming level, even also at the modeling level. Though, in some cases the application of these techniques is independent of the problem itself. In other words, the techniques for weaving either cod...

We propose a change management framework for Service-Oriented Enterprise (SOEs). We present a taxonomy of changes that occur in SOEs, whereby we focus on bottom-up changes. We use a combination of Ordinary Petri nets and Reconfigurable Petri nets to model the triggering changes and reactive changes, respectively. We propose an automatic change management framework that is based on the above Pet...

The application of ontologies (semantic) to enhance any existing or proposed Service-Oriented Architecture (SOA) based software architecture has various levels of use in terms of intra and inter enterprise integration. The use of ontologies in an architectural design and development methodology of any service-oriented enterprise software holds the key to offer a dynamic, flexible and scalable s...

The SHAMAN project targets a framework integrating advances in the data grid, digital library, and persistent archives communities in order to archive a longterm preservation environment. Within the project we identified several challenges for digital preservation in the area of memory institutions, where already existing systems start to struggle with e.g. complex or many small objects. In ord...

It is increasingly important that Service Level Agreements (SLAs) are taken into account when business processes are exposed as services in a Service Oriented Architecture. SLAs define expected service behavior and nonfunctional properties of the service. The fact that the service provider has to offer certain guarantees concerning SLA properties has an impact on the business process lifecycle....

Spatial Data Infrastructures (SDIs) have been developing in some countries for over 10 years but still suffer from having a relatively small installed base. Most SDIs will soon converge around a service-oriented-architecture (SOA) using IT standards promulgated primarily by the Open Geospatial Consortium (OGC) and ISO Technical Committee 211. There are very few examples of these types of archit...

Previous research has shown that when two color-defined target objects appear in rapid succession at different locations, attention is deployed independently and in parallel to both targets. This study investigated whether this rapid simultaneous attentional target selection mechanism can also be employed in tasks where targets are defined by a different visual feature (shape) or when alphanume...

An integrated management of business processes demands a strictly process-oriented development of the supporting IT. Process-orientation is especially promoted by Service-Oriented Architectures (SOA), where loosely coupled business services are being composed to executable processes. In this paper we present a model-driven methodology for a top-down development of a process-oriented IT support ...

Agent-oriented modeling is a top-down approach for modeling and simulating the behaviors of complex systems. This research addresses the application of agent-oriented modeling to eliciting and representing knowledge for social simulations. We provide an overview of agent-oriented modeling and describe a case study on conflict resolution that has an impact on winning “hearts and minds” of the oc...
