Abstract
In the service development life cycle it is worthwhile to distinguish between a conceptual phase, that leads to model abstract services, and a production phase that produces concrete services. Both abstract and concrete services produced by a provider organization can be organized, for reuse purposes, in structured repositories of services. As occurs in database design for conceptual schemas, in a single provider organization several repositories of services may coexist, potentially characterized by heterogeneities and conflicting representations. In this paper we present an experience of integration of repositories of abstract services, based on a methodology currently under development.
Highlights
In the last ten years Service Science [7] has evolved from a pioneering field to an emerging multidisciplinary research area, attaining a growing mainstream resonance and scientific recognition
The Service Oriented Computing paradigm and service oriented design and development methodologies support the realization of service-based ICT infrastructures [23], covering only one perspective among the many considered in initiatives aimed at designing and planning services in service ecosystems
In this paper we have presented a methodology for service repository integration that was conceived in the course of a project, whose aim was to design services in various application domains that provide value to users and providers
Summary
In the last ten years Service Science [7] has evolved from a pioneering field to an emerging multidisciplinary research area, attaining a growing mainstream resonance and scientific recognition. One of the paradigms that inspires the methodology, is that, as in other production processes of ICT artifacts such as e.g. database design, two representation levels for services are significant, that we call: Abstract services, established by law and having an owner (e.g. for a business, the service “obtain an authorization to open a cafeteria” whose owner are Chambers of Commerce) and Concrete services, provided by a specific provider, e.g. the previous service provided by a Chamber of Commerce or by a private provider Another relevant concept in SMART is the repository of services, that plays in the service life cycle the role of the software applications repository in software engineering. For repositories of services an integration step is needed, to create a reconciled and integrated representation of all services produced and managed in the organization: this is the problem discusses in the paper.
