Does anything prevent a view from being de … Does anything prevent a view from being defined as infinitely recursive, leading to a dataset that has no fixpoint? The paper briefly mentions in section 7 (Complexity) that they limit discussion to only construct patterns without blank nodes (required to create an infinite dataset), section 5 (Semantics) seems to imply that such models are allowed, yet the discussion seems to gloss over how the implementation deals with this (ignoring the problem by assuming a fixpoint will be reached eventually). ng a fixpoint will be reached eventually).
