Data Quality Notification in Cooperative Information Systems
نویسندگان
چکیده
Current approaches to the development of cooperative information systems are based on services to be offered by cooperating organizations, and on the opportunity of building coordinators and brokers on top of such services. The quality of data exchanged and provided by different services hampers such approaches, as data of low quality can spread all over the cooperative system. At the same time, improvement can be based on comparing data, correcting them and disseminating high quality data. In this paper, we consider the problem of disseminating quality information. In particular, we describe the Quality Notification Service, whose objective is to provide cooperating entities with information concerning the quality variations of exchanged data. By exploiting the information supplied by the Quality Notification Service, other applications and services can be built or modified to benefit of notifications of quality variations.
