Peer Data Exchange
Summary: Defines peer data exchange, a generalization of data exchange that models authority relations between peers via source-to-target and target-to-source constraints, with the target augmentable but not allowed to modify source data. Studies the fundamental solution-existence problem: proves it is in NP and can be NP-complete (even for “acyclic” settings), shows certain-answer data complexity is coNP/coNP-complete, and identifies tight syntactic fragments (e.g., arbitrary TGDs s→t with LAV t→s) that yield polynomial-time solvability.
