if logic is translation equivalent, at the level of sentences, with a number of other logical systems based on team semantics, such as dependence logic, dependence-friendly logic, exclusion logic and independence logic; with the exception of the latter, if logic is known to be equiexpressive to these logics also at the level of open formulas. however, if logic differs from all the above-mentioned systems in that it lacks "locality" (the meaning of an open formula cannot be described just in terms of the free variables of the formula; it is instead dependent on the context in which the formula occurs).
