Résumé
Kiabora is a software tool dedicated to the analysis of a base of existential rules (also called Datalog± rules). It is able to check if a set of rules belongs to a known class for which entailment is decidable, either directly, by checking some syntactic properties, or by means of its Graph of Rule Dependencies, which allows to combine decidable cases. Kiabora is available online via a simple web form. It is written in Java and is easily extensible to take new decidability results into account. It comes with a textual format, called DLGP (for Datalog Plus), which can be seen as an extension to usual plain Datalog format. In this paper, we briefly introduce the existential rule framework as well as decidability results and presents the analysis performed by Kiabora. More details are available on Kiabora website.
