In Peer Data Management Systems, several autonomous data peers are combined to a larger system by defining semantic relations between their data. Because cycles in these relations often render many important reasoning tasks undecidable, defining the semantics of such systems turned out to be challenging. De Giacomo et al. (2007) proposed a theoretical framework that allows for an arbitrary topology of the data network, applying a weaker semantics (compared to the often used first-order logic) to the mappings. We report on a prototype implementation of this framework, present first evaluation
results and state our findings during implementation.
