In this paper we analyse the use of patterns across a number of fields including architecture, software development and educational technology design. Focusing on the reusability of a pattern outside its area of development, we have identified several issues related to the context and the value system of a pattern. The paper draws together lessons learned from different fields where patterns ar...

Design pattern instance recognition is often done by static analysis, thus approaches are limited to the recognition of static parts of design patterns. The dynamic behavior of patterns is disregarded and leads to lots of false positives during recognition. This paper presents an approach to combine the advantages of static and dynamic analyses to overcome this problem and improve the design pa...

The need for a representation language for ontology design patterns has long been recognized. However, the body of literature on the topic is still rather small and does not sufficiently reflect the diverse requirements on such a language. Herein, we propose a simple but useful and extendable approach which is fully compatible with the Web Ontology Language and should be easy to adopt by the co...

In this paper, we aim to study design patterns in the context of a software package called MDV (MetaData Visualisation). The development of this software was relatively fast-paced and performed by a team split into two physical locations for large part of the most active development period. The original design documents did not contain any overt use of design pattern methodology and all of the ...

Design patterns capture expert design experience in generic design structure and behavior. To reuse design experience, a design pattern needs to be instantiated from its generic template to the application design in a particular context. It can be integrated with other patterns to solve multiple design problems. The instantiation and integration of design patterns are two important processes wh...

Naming is an important, but frequently overlooked, aspect of software systems. Usually, naming appears combined with other issues, e.g. distributed communication technology. This paper treats naming in isolation. It presents a naming design pattern which abstracts several naming policies and an object-oriented framework that can be customized to support naming policies. Applications designer ca...

The pattern “Define Hybrid Class Resolving Disjointness due to Subsumption” is proposed as a Logical Ontology Design Pattern (Logical OP) solving a problem of disjointness inconsistency caused by a subsumption relation. Further away from solving design problems where the primitives of the representation language do not directly support certain logical constructs, this pattern helps resolving a ...

The Hazardous Situation ontology design pattern models the consequences of exposure of an object to a hazard. In its current form, the ODP is well suited for representing the consequences of exposure after the fact, which is very useful for applications such as damage assessment and recovery planning. In this work, we present a modification to this pattern that enables it to additionally suppor...

Human centered systems must focus attention in roles, users and tasks, aiming to making the full potential of computing ubiquitous. The paper proposes a generic design pattern for such systems, incorporating digital assistants and human representatives. These agents collaborate with people and deliberate socially for helping them to (a) participate in numerous physical and social contexts consi...

This paper demonstrates how to use Simkit to create Discrete Event Simulation models using a component framework. The component framework is based on a listener design pattern especially useful for simulation models. The objects created are called Listener Event Graph Objects, so the component framework is called LEGO. Simkit is an Open Source package written in Java.
