    On Systematic Design of Service-Oriented Architectures
    (2008) Kanagwa, Benjamin; Mugisa, Ezra K.; van der Weide, Th.P.
    We present a systematic means of designing serviceoriented systems. Because services are developed independently, with no prior knowledge about each other, there is only a limited possibility that such services use similar message templates, initiate calls to any other service, or generate messages to support desired architecture configurations. As a result, construction of service-oriented systems rely on intermediary services to preprocess, transform and route messages to appropriate locations. The paper suggests a systematic design for the intermediary services and construction of services-oriented systems using a reuse drive approach. The approach is founded on category theory- a formal foundation for capturing and preserving structures. The approach supports parallel and incremental inter-connection of services in a planned and reusable manner

    Web Content Filtration according to context of use: Case Study of Accessibility Guidelines
    (Fountain Publishers, 2009) Baguma, Rehema; Lubega, Jude T.; Stone, Roger G.; van der Weide, Th.P.
    In this paper, we propose an approach for filtering Web based content according to context of use based on user roles and other use case scenarios. The purpose of the filtration approach is to make such Web content easier to use for the target audience. Context of use is important for the usability of Web based content particularly that used by different groups of people with different roles, interests and skill base. We use the Web content accessibility guidelines (WCAG) to demonstrate how the approach can be used to improve usability of Web based content. Other than accessibility guidelines, the approach is relevant to ANY Web based content for any subject if intended for multiple classes of users.
