Transitioning Applications to Semantic Web Services: An Automated Formal Approach

Semantic Web Services have been recognized as a promising technology that exhibits huge commercial potential, and attract significant attention from both industry and the research community. Despite expectations being high, the industrial take-up of Semantic Web Service technologies has been slower than expected. One of the main reasons is that many systems have been developed without considering the potential of the web in integrating services and sharing resources. Without a systematic methodology and proper tool support, the migration from legacy systems to Semantic Web Service-based systems can be a very tedious and expensive process, which carries a definite risk of failure. There is an urgent need to provide strategies which allow the migration of legacy systems to Semantic Web Services platforms, and also tools to support such a strategy. In this paper we propose a methodology for transitioning these applications to Semantic Web Services by taking the advantage of rigorous mathematical methods. Our methodology allows users to migrate their applications to Semantic Web Services platform automatically or semi-automatically

Unity in Diversity Through Art? Joseph Beuys’ Models of Cultural Dialogue

This essay proposes the artist Joseph Beuys and his work as paradigmatic for art that through its own diversity of approach can show possibilities for addressing diverse audiences, diverging receptions and modes of participation. It arises from a symposium on the occasion of the 20th anniversary of the artist’s death held at the Goethe Institut Dublin, 23 January 2006. The argument focuses on Beuys practice from his Ulysses-Extension to the Migration Workshop at documenta 6, 1977, the FIU, as well as his work (and legacy) in Ireland. Relevant theories include Ecos openness and Adorno’s negative and positive representation, since Beuys works relationship to the Holocaust and trauma turns out to be central. Beuys is offered as predecessor of current discourse such as Bourriaud’s Relational Aesthetics and Documenta11. The article concludes with a new theoretization of participation in culture, Irit Rogoff’s Looking Away. It is supported by Beuys multi-layered, diversity-sustaining practice.Cultural Dialogue, Joseph Beuys, Diversity, Reception, Participation, Migration, documenta, FIU, Ireland, Openness, Holocaust, Trauma, Relational Aesthetics

Scarcity in IP addresses: IPv4 Address Transfer Markets and the Regional Internet Address Registries

We are running out of Internet addresses. This paper evaluates address transfer policies that Internet governance agencies are considering as a response to the depletion of the IPv4 address space. The paper focuses on proposals to allow organizations holding IPv4 addresses to sell address blocks to other organizations willing to buy them. This paper analyzes the economics of the proposed transfer policies, and conducts a systematic comparison of the policies proposed in the three main world Internet regions

Child Exploitation and the FIFA World Cup: A review of risks and protective interventions

This review was commissioned by the Child Abuse Programme (CAP) of Oak Foundation, a large international philanthropic organisation. It forms part of CAP’s effort to win societal rejection of practices such as the sexual exploitation of children and adolescents around major sporting events (MSEs), and to embed prevention and protection from exploitation as a permanent concern for global sports-related bodies. This review is intended to inform action in countries that host MSEs and to provide some suggestions on how hosting countries can avoid past pitfalls and mistakes in relation to child exploitation, especially economic and sexual exploitation. Importantly, it also acts as a call to action by those responsible for commissioning and staging MSEs, such as FIFA and the IOC, to anticipate, prepare for and adopt risk mitigation strategies and interventions. Positive leadership from these culturally powerful bodies could prove decisive in shifting hearts, minds and actions in the direction of improved safety for children

A Systematic Aspect-Oriented Refactoring and Testing Strategy, and its Application to JHotDraw

Aspect oriented programming aims at achieving better modularization for a system's crosscutting concerns in order to improve its key quality attributes, such as evolvability and reusability. Consequently, the adoption of aspect-oriented techniques in existing (legacy) software systems is of interest to remediate software aging. The refactoring of existing systems to employ aspect-orientation will be considerably eased by a systematic approach that will ensure a safe and consistent migration. In this paper, we propose a refactoring and testing strategy that supports such an approach and consider issues of behavior conservation and (incremental) integration of the aspect-oriented solution with the original system. The strategy is applied to the JHotDraw open source project and illustrated on a group of selected concerns. Finally, we abstract from the case study and present a number of generic refactorings which contribute to an incremental aspect-oriented refactoring process and associate particular types of crosscutting concerns to the model and features of the employed aspect language. The contributions of this paper are both in the area of supporting migration towards aspect-oriented solutions and supporting the development of aspect languages that are better suited for such migrations.Comment: 25 page

Abmash: Mashing Up Legacy Web Applications by Automated Imitation of Human Actions

Many business web-based applications do not offer applications programming interfaces (APIs) to enable other applications to access their data and functions in a programmatic manner. This makes their composition difficult (for instance to synchronize data between two applications). To address this challenge, this paper presents Abmash, an approach to facilitate the integration of such legacy web applications by automatically imitating human interactions with them. By automatically interacting with the graphical user interface (GUI) of web applications, the system supports all forms of integrations including bi-directional interactions and is able to interact with AJAX-based applications. Furthermore, the integration programs are easy to write since they deal with end-user, visual user-interface elements. The integration code is simple enough to be called a "mashup".Comment: Software: Practice and Experience (2013)

Migrating Legacy Systems in the Global Merger & Acquisition Environment Teaching Case

MetaFrame system migration project at Worldpharm, driven by the fiesta of merger and acquisition, had engendered both technical challenges and convoluted organizational issues in the climate of uncertainties. This project was aligned with IT strategy that aimed to streamlining IT resources and enhancing system efficiency of the post-merger organization. In spite of recognizing that it was treading in the treacherous water, Worldpharm still insisted on instigating this post-merger MetaFrame system migration project, which served to (1) consolidate all legacy MetaFrame systems from the three pre-merger pharmaceutical organizations into one globally managed system and (2) develop a global support team for the globally managed MetaFrame system
