Forum Session at the First International Conference on Service Oriented Computing (ICSOC03)

The First International Conference on Service Oriented Computing (ICSOC) was held in Trento, December 15-18, 2003. The focus of the conference ---Service Oriented Computing (SOC)--- is the new emerging paradigm for distributed computing and e-business processing that has evolved from object-oriented and component computing to enable building agile networks of collaborating business applications distributed within and across organizational boundaries. Of the 181 papers submitted to the ICSOC conference, 10 were selected for the forum session which took place on December the 16th, 2003. The papers were chosen based on their technical quality, originality, relevance to SOC and for their nature of being best suited for a poster presentation or a demonstration. This technical report contains the 10 papers presented during the forum session at the ICSOC conference. In particular, the last two papers in the report ere submitted as industrial papers

Ubiquitous Grid Service Interoperation Protocol through Polyarchical Middleware

Next generation software applications will be required to run on globally distributed heterogeneous assemblies of disparate resources including: emerging computing grids. Such application calls for seamless integration and interoperation between varieties of service standards and architectures developed and deployed using existing service middleware standards and architectures such as; DCOM, COBRA, Jini, Web service UPnP. Whilst such middleware adequately provide different APIs, programming models for distributed components and services integration and interoperation at both design and runtime. There is still need for additional middleware service to support runtime services invocation regardless of the components/service standards and type of middleware used. Based on an ongoing research focusing on self-adaptive software for adaptive middleware, this paper will describe a proposed on-demand (runtime) service invocation mechanism, and the associated service interoperation protocol. This will be followed by a brief introduction of a proposed polyarchical middleware, which is capable of discovery/lookup service components, dynamic service invocation adaption, and service interoperation management of given end-user applications

Polyarchical Moddleware for On-Demand and Multi-Standard Services' Composition for Ubiquitous Computing

Whilst the vision of on-demand computing is very seductive it engenders its own technical challenges including: design, development and deployment of ubiquitous utility services, and low-cost, low-skills and low-latency services re-assembly for lifetime management runtime due to complex and unpredicted service discovery, interoperation and adaptation. In this paper we argue for the need of a new model for on-demand ubiquitous services' activation through a polyarchical middleware, which enables on-demand composition of software applications regardless of service standards and middleware used. This paper will present early results of a research study into the development of a framework for ubiquitous service invocation/activation, which provides an abstract model for on-demand ubiquitous service composition and execution. This proposed polyarchical middleware could be used for on-demand wireless application service composition, which include ad-hoc service discovery, assembly using virtual containers, invocation and adaptation. The paper will finish with a critical review of our model and concluding remarks followed by an indication of further work Services' Composition for M. Yu, A. Taleb-Bendiab, D.
