Provalets OSGi-based prova agents for rule-based data access

Abstract

Rule-based Data Access (RBDA) has become an active R&D topic in the recent years. In this paper we propose an easy to use agentbased rule programming model and a general component architecture for RBDA. The programming model supports rapid prototyping and reuse of existing Prova rule agents/components which are published and managed in OntoMaven repositories. We name these components Provalets. We propose a declarative component description language that is powerful enough to represent different types of Provalets, including the representation of their functional interfaces and their semantics as well as their non-functional collaboration aspects and quality of service attributes.
