The workshop gave rise to rich discussions and an open issue emerged: how to define fragments of existential ASP covering lightweight ontological languages while keeping decidability and efficiency?
V * D on pseudovarieties preserves decidability of the separation problem, while it has been shown by Auinger (2010) that it does not preserve decidability of the membership problem (on the other hand, the status with respect to separation is unknown for other operators that do not preserve the decidability of membership, such as the power, as shown by Auinger and Steinberg (2003)).

This broad conception is linked to a series of sub-peculiar theories considered as typical of legal positivism such as the imperativistic theory, the coactionistic theory, the legal sources theory, the theory of declarative interpretation of law, the theory of legal system considered as a structured whole whose semantic features are completness, consistency and decidability.
