Abstract
Abstract: Our era has been marked by the emergence of the service oriented computing (SOC) paradigm. This new trend has reshaped the way distributed applications are built and has influenced current computing paradigms, such as p2p and grid computing. SOC’s main objective is to leverage interoperability among applications and systems; however, the emergence of various types of services such as web, grid and p2p services has raised several interoperability concerns among these services as well as within each of these service models. In order to surpass these incompatibilities, appropriate middleware and mechanisms need to be developed so as to provide the necessary layers of abstraction and a unified framework that will obscure a service user from the underlying details of each service platform. Yet, for the development of such middleware and mechanisms to be effective, appropriate conceptual models need to be constructed. Within this paper, we briefly present a generic service model which was constructed to facilitate the unified utilization of heterogeneous services, with emphasis on its properties for the modeling of p2p services. Moreover, we illustrate how this model was instantiated for the representation of JXTA services and present the service description and discovery mechanisms that were built upon it. We regard this generic service model as a first step in achieving interoperability between incompatible types of services. 1
