In this paper, we describe design and implementation of a Java interface for distributed reasoning on networked ontologies with alignments. This API is built over the standard OWLlink interface which is a communication protocol between OWL2 components. It is compatible with usual reasoners based on OWL such as Pellet and FaCT++ in centralized contexts. In this API, we have implemented an optimized distributed reasoning algorithm which, on the one hand requires specific primitives to manipulate OWL ...
