TL;DR: This report outlines a methodology to model check declarative models of artifact-centric systems by translating GSM-based artifacts into a symbolic transition system used for symbolic model checking and implements the methodology in the GSMC model checker.

TL;DR: A method for verifying structural equivalence of DTDs is provided, which works in worst case deterministic exponential time, in contrast to the known algorithms for this problem which are double exponential.

TL;DR: This work proposes an approach to automatically generate an extension to the original business process model that, when executed after a constraint violation, repairs the contents of the data leaving it in a new consistent state.

TL;DR: It is shown that LDLf is able to capture, in the logic itself, not only the constraints to be monitored, but also the de-facto standard RV-LTL monitors, which makes it possible to declaratively capture monitoring metaconstraints, and check them by relying on usual logical services instead of ad-hoc algorithms.

TL;DR: This work investigates supervision of an agent that may acquire new knowledge about her environment during execution, for example, by sensing, and defines a notion of online situation-determined agent which ensures that for any sequence of actions the agent can perform online, the resulting agent configuration is unique.
