Abstract

Data Integration/Exchange (DI/DE) has seen great developments both in the Databases (DB) and the Semantic Web (SW) areas. ForBackBench has been the first framework that facilitates the comparison of systems from both areas by introducing datasets, converters and algorithms that allow for integration and interaction of different query rewriting (OBDA) and forward-chaining (Chase) systems. In this paper, we discuss the most recent developments of the framework, which aim to completely bridge the gap between the DB and SW areas in DI/DE field by integrating RML (and R2RML) ontology materialisation systems. To facilitate translations between mapping languages (R2RML, RML, OBDA) and tuple-generating dependencies (TGDs), we introduce a special language of source-to-source TGDs with built-in functions. We integrate state-of-the-art ontology materialisation systems from SW as well as datasets and scenarios from that area. Our initial experimental results already shed light on the interaction of these areas and the properties of different algorithms and systems, exhibiting the merits of our framework.
