A robust client-driven distributed service localisation architecture
MetadataShow full item record
The fundamental purpose of service-oriented computing is the ability to quickly provide software resources to global users. The main aim of service localisation is to provide a method for facilitating the internationalisation and localisation of software services by allowing them to be adapted to different locales. We address lingual localisation by providing a service interface translation using the latest web services technology to adapt services to different languages and currency conversion as an example of regulatory localisation by using real-time data provided by the European Central Bank. Units and Regulatory Localisations are performed by a conversion mapping, which we have generated for a subset of locales. The aim is to investigate a standardised view on the localisation of services by using runtime and middleware services to deploy a localisation implementation. We apply traditional software localisation ideas to service interfaces. Our contribution is a localisation platform consisting of a conceptual model classifying localisation concerns and the definition of a number of specific platform services. The architecture in which this localisation technique is client-centric in a way that it allows the localisation to be controlled and managed by the client, ultimately providing more personalisation and trust. It also addresses robustness concerns by enabling a fault-tolerant architecture for third-party service localisation in a distributed setting.
